Resizing Disk Space on BIG-IQ Virtual Edition

BIG-IQ Virtual Edition Disk Space Overview

BIG-IQ® Virtual Edition (VE) uses Logical Volume Management (LVM) to allow you to use utilities to resize file systems. Additional disk space is useful when you need more storage on your BIG-IQ system for things such as logging or database files.

Here is an example of an initial installation of BIG-IQ 5.2 VE with a single installation slot created on volume HD1.1


  [root@bigiq-console-test-large:Active:Standalone] ~ # tmsh show sys software 
  
  ----------------------------------------------------
  Sys::Software Status
  Volume  Product  Version     Build  Active    Status
  ----------------------------------------------------
  HD1.1    BIG-IQ    5.2.0  0.0.5741     yes  complete

The size of each file system is determined by a configuration file within the BIG-IQ installation image. (For details, refer to Default Filesystem Sizes on support.f5.com.)

You can use the command lvs to see the file structure on your BIG-IQ VE. The response shows all of the default logical volumes created, along with their size, in kilobytes.

Here is an example of an a typical BIG-IQ 5.2 VE file system.


  [root@bigiq-console-test-large:Active:Standalone] ~ # lvs --unit=k
  LV            VG        Attr      LSize        Pool Origin Data%  Move Log Cpy%Sync Convert

  dat.maint.1   vg-db-sda -wi-a----   307200.00k
  dat.share.1   vg-db-sda -wi-ao--- 10240000.00k
  dat.swapvol.1 vg-db-sda -wi-ao---  1048576.00k

  set.1._usr    vg-db-sda -wi-ao---  3452928.00k
  set.1._var    vg-db-sda -wi-ao--- 10485760.00k
  set.1.root    vg-db-sda -wi-ao---   450560.00k

When you upgrade to version 5.3 or 5.4, BIG-IQ, one of the installation steps creates a new slot using the create-volume parameter. Another installation step reveals the resulting file structure.

Here is an example from a typical BIG-IQ 5.2 to 5.3 upgrade:


  [root@bigiq-console-test-large:Active:Standalone] ~ # tmsh install sys software image BIG-IQ-5.3.0.0.0.1119.iso create-volume volume HD1.2
[root@bigiq-console-test-large:Active:Standalone] ~ # tmsh show sys software
 
-----------------------------------------------------------------
Sys::Software Status
Volume  Product  Version     Build  Active                 Status
-----------------------------------------------------------------
HD1.1    BIG-IQ    5.2.0  0.0.5741     yes               complete
HD1.2    BIG-IQ    5.3.0  0.0.1119      no  installing 10.000 pct

The following example illustrates what the logical volumes look like after you install the new BIG-IQ software.


 [root@bigiq-console-test-large:Active:Standalone] ~ # lvs --unit=k
  LV            VG        Attr      LSize        Pool Origin Data%  Move Log Cpy%Sync Convert
  dat.log.1     vg-db-sda -wi-ao---  7168000.00k
  dat.maint.1   vg-db-sda -wi-a----   307200.00k
  dat.share.1   vg-db-sda -wi-ao--- 10240000.00k
  dat.swapvol.1 vg-db-sda -wi-ao---  1048576.00k
  set.1._config vg-db-sda -wi-ao---  3321856.00k
  set.1._usr    vg-db-sda -wi-ao---  3452928.00k
  set.1._var    vg-db-sda -wi-ao--- 10485760.00k
  set.1.root    vg-db-sda -wi-ao---   450560.00k
  set.2._config vg-db-sda -wi-a----  3321856.00k
  set.2._usr    vg-db-sda -wi-a----  3452928.00k
  set.2._var    vg-db-sda -wi-a---- 10485760.00k
  set.2.root    vg-db-sda -wi-a----   450560.00k

Each installation volume has their own root, /usr, /config, and /var filesystems. The filesystems are mounted on logical volumes named using the following naming convention: vg--db--sda-set.<installation slot>.<filesystem alias>.

This table illustrates the mapping structure.

Installation Slot Logical Volume Mount Point Notes
Shared dat.log.1 /var/log Shared across all installation slots
Shared dat.share.1 /shared Shared across all installation slots
HD1.1 set.1._config /config Slot 1 only
HD1.1 set.1._usr /usr Slot 1 only
HD1.1 set.1._var /var Slot 1 only
HD1.1 set.1.root / Slot 1 only
HD1.2 set.2._config /config Slot 2 only
HD1.2 set.2._usr /usr Slot 2 only
HD1.2 set.2._var /var Slot 2 only
HD1.2 set.2.root / Slot 2 only

Default filesystem sizes

The BIG-IQ installation image contains the information used to configure logical volumes with default sizes. These default sizes are referred to as plans. If you install a new BIG-IQ version and the existing logical volumes in the target installation slot are not at least as large as the default size, then the installation process deletes and recreates the entire slot with the default logical volume sizes spelled out in the plan for the installation image. If you want to see the sizes defined in the plan for your BIG-IQ system, you can use a script named imageplan.

Here is an example of the plans defined for a BIG-IQ 5.1 installation:


  [root@bigiq-console-test-large:Active:Standalone] ~ # imageplan /shared/images/BIG-IQ-5.1.0.0.0.631.iso
product BIG-IQ version 5.1.0 build 0.0.631 (BIGIQ510) selected
Standard plan
  Mount point: /, Size: 300000k
  Mount point: /usr, Size: 2350000k
  Mount point: /config, Size: 1048576k
  Mount point: /var, Size: 10485760k
Tiny plan
  Mount point: /, Size: 300000k
  Mount point: /usr, Size: 2350000k
  Mount point: /config, Size: 1048576k
  Mount point: /var, Size: 10485760k

Here is an example of the plans defined for a BIG-IQ 5.2 installation:


  [root@bigiq-console-test-large:Active:Standalone] ~ # imageplan /shared/images/BIG-IQ-5.2.0.0.0.5741.iso
product BIG-IQ version 5.2.0 build 0.0.5741 (BIGIQ520) selected
Standard plan
  Mount point: /, Size: 450000k
  Mount point: /usr, Size: 3450000k
  Mount point: /config, Size: 3320000k
  Mount point: /var, Size: 10485760k
Tiny plan
  Mount point: /, Size: 450000k
  Mount point: /usr, Size: 3450000k
  Mount point: /config, Size: 500000k
  Mount point: /var, Size: 10485760k

As illustrated in these examples, for BIG-IQ version 5.1 and 5.2, the Standard and Tiny plans use the same sizes for the/, /usr, and /var mount points. The size for the /config mount point often changes for each plan.

When you install BIG-IQ software, the installation process reads the plan for the version you are installing and then uses either the Standard or the Tiny plan depending upon the total disk size available in the target installation slot.

Filesystem details

This table describes the contents of a folder structure on a typical BIG-IQ® VE.

File System Contains Notes
/shared Shared across all installation volumes:
  • ucs backups

    /shared/ucs_backups

  • BIG-IQ and BIG-IP installation ISO images

    /shared/images

  • ssh keys, known_hosts files, etc. /shared/ssh
  • core files

    /shared/core

Consider resizing this disk if there are many UCS backups (for example, if you have lots of BIG-IP devices to manage) or software installation images, or if the size of the BIG-IQ UCS file itself, which contains data from /var/config could be too large for a successful upgrade.
/var/log Processes logging data shared across all installation volumes:
  • restjavad logs

    /var/log/restjavad*

  • database logs /var/log/tokumx.log.*
  • configuration search index logs /var/log/searchd/eslognode*
  • data collection device logs /var/log/elasticsearch/eslognode*
Consider resizing this disk if the default log rotation policies do not handle actual logging volume.
/ (root) Linux operating system components and configuration  
/usr BIG-IQ installation binary and configuration components  
/var BIG-IQ data:
  • restjavad configuration data /var/config/rest/toku/data
  • restjavad configuration search indexes /var/config/rest/searchd/data
  • data collection device indexes /var/config/rest/elasticsearch/data
Consider resizing this disk if the database or index growth will exceed current disk capacity.

What factors should I consider before resizing my disks for an upgrade?

The commands for extending the filesystem on your BIG-IQ® VE are very straightforward, but there are a things you should consider before proceeding.

Questions to ask before you resize

  • Do you have enough disk space on the BIG-IQ VE to install the BIG-IQ software?
  • How big are the volumes needed by the software you want to install?
  • How big are the volumes on your current BIG-IQ installation?
  • Do you have an open slot to install the software on?

Check the disk space on the BIG-IQ VE

Before you create new slots and size them appropriately, you need to check that there is sufficient physical disk space on the VE. You can use the pvs command to check. For example:


[root@bigiq-console-test-large:Active:Standalone] ~ # pvs
  PV         VG        Fmt  Attr PSize   PFree
  /dev/sda3  vg-db-sda lvm2 a--  498.50g 446.82g

This device has 446 Gigs of free disk space. That would be more than sufficient for a standard 5.4 install (30G +5G + 5G + 10G = 50G)

Once you know how much room you need and if there is room on the VE you are installing on, you can start extending the disk. Remember that the volume sizes on the target slot must be at least as big as the volumes on your current slot. So if you have extended the volume sizes on your current installation, you will need larger volumes than the minimum sizes specified in the image plan for the software image you are installing. You need to use the larger of the two values from the checks you just completed. For example, if the imageplan script shows a /var size of 10G is needed for the software you want to install, but the show sys software check shows a /var size of 30G for the version you currently have installed, then you need the /var volume to be sized at 30G, not 10G.

Check the volume sizes required by the software you want to install

F5 has created a script that reads the size requirements from the software image you plan to install and then creates them for you on a new installation slot. To use this script:
  1. Copy the software image to the /shared/images folder on the BIG-IQ system you plan to upgrade:
    
     [root@bigiq-test:Active:Standalone] ~ # cp  <big-iq-software-image>.iso /shared/images/<big-iq-software-image>.iso
       
    
  2. Run the imageplan script on the software image to determine the filesystem sizes required:
    
     [root@bigiq-test:Active:Standalone] ~ # ./imageplan /shared/images/<big-iq-software-image>.iso
    product BIG-IQ version 5.3.0 build 0.0.1119 (BIGIQ530) selected
    Standard plan
      Mount point: /, Size: 450000k
      Mount point: /usr, Size: 3450000k
      Mount point: /config, Size: 3320000k
      Mount point: /var, Size: 10485760k
    Tiny plan
      Mount point: /, Size: 450000k
      Mount point: /usr, Size: 3450000k
      Mount point: /config, Size: 500000k
      Mount point: /var, Size: 10485760k
    
    

Now you know the size requirements for the image you plan to install.

Check the volume sizes on your current BIG-IQ installation

You need to know the volume sizes for your current installation, because if any of the volumes have been extended, you must likewise extend the volumes on the installation slot before you upgrade. Otherwise, the install process can result in loss of data. To check the volume sizes of the existing installation, you can use the tmsh command show sys software . For example:


    [root@bigiq-test:Active:Standalone] config # tmsh show sys software
 
----------------------------------------------------
Sys::Software Status
Volume  Product  Version     Build  Active    Status
----------------------------------------------------
HD1.1    BIG-IQ    5.2.0  0.0.5567     yes  complete
 
[root@bigiq-test:Active:Standalone] config # lvs --unit=k
  LV            VG        Attr      LSize        Pool Origin Data%  Move Log Cpy%Sync Convert
  dat.log.1     vg-db-sda -wi-ao---  7168000.00k
  dat.maint.1   vg-db-sda -wi-a----   307200.00k
  dat.share.1   vg-db-sda -wi-ao--- 10240000.00k
  dat.swapvol.1 vg-db-sda -wi-ao---  1048576.00k
  set.1._config vg-db-sda -wi-ao---   503808.00k
  set.1._usr    vg-db-sda -wi-ao---  3452928.00k
  set.1._var    vg-db-sda -wi-ao--- 31457280.00k
  set.1.root    vg-db-sda -wi-ao---   450560.00k

The system response shows you the volume sizes of your current installation. The key volumes with their sizes are listed below:
  • /config (.5G)
  • /usr (3.5G)
  • /var (30G)
  • /root (.5G)
The slot you upgrade to must have volumes that are at least as big as those on the slot your software is currently installed on. This is especially significant if you decided to extend one of the volumes on your current installation. So if your /var is extended to 30G, you must have at least that much space on the new slot before you install software.

Check to see if you have an open slot to install the software on

Before you can install new software, you need an open slot. You can use the lvs command to determine how many slots there are on your BIG-IQ VE. For example:


[root@bigiq-console01:Active:Standalone] config # lvs --unit=k
  LV            VG        Attr      LSize        Pool Origin Data%  Move Log Cpy%Sync Convert
  dat.log.1     vg-db-sda -wi-ao---  8388608.00k
  dat.maint.1   vg-db-sda -wi-a----   307200.00k
  dat.share.1   vg-db-sda -wi-ao--- 33554432.00k
  dat.swapvol.1 vg-db-sda -wi-ao---  1048576.00k
  set.1._config vg-db-sda -wi-a----   503808.00k
  set.1._usr    vg-db-sda -wi-a----  3452928.00k
  set.1._var    vg-db-sda -wi-a---- 10485760.00k
  set.1.root    vg-db-sda -wi-a----   450560.00k
  set.2._config vg-db-sda -wi-ao---  3481600.00k
  set.2._usr    vg-db-sda -wi-ao---  3584000.00k
  set.2._var    vg-db-sda -wi-ao--- 16003072.00k
  set.2.root    vg-db-sda -wi-ao---   512000.00k
  set.3._config vg-db-sda -wi-a----  3321856.00k
  set.3._usr    vg-db-sda -wi-a----  3452928.00k
  set.3._var    vg-db-sda -wi-a---- 10485760.00k
  set.3.root    vg-db-sda -wi-a----   450560.00k

Each instance of set.n represents a slot on the VE. So in this example the VE has 3 installation slots (set.1, set.2, and set.3).

Resizing disk volumes for a BIG-IQ upgrade (an example workflow)

The workflow for extending your disk volumes so that you can successfully upgrade to a new version of BIG-IQ and preserve your current data is listed below:
  • If you need more physical disk space, attend to that first.
  • If you have the disk space and an open slot, then F5 has a script that you can use to create the new volumes required for the image you plan to install. addvol reads the image plan for the software you plan to install and creates the volumes required.
  • If you have extended the disk space on your current installation, F5 has a script that increases volume size as needed. resizevol sets the volume size to the value you specify.
  • If you need an extra slot, you can add it as part of the installation command. The create_volume parameter adds a new slot to your VE and (if you've set up the volume sizes correctly using addvol and resizevol) when the software upgrades, all of your data fits without any disk resizing. Resizing disks in the middle of an upgrade can cause you to lose data.
The following example tasks step you through the workflow for extending your disk size as part of an upgrade. In this scenario, you check the disk space first, then you create the volumes for the software you plan to install, then you extend a volume to account for an extension you performed on your current installation, and finally, you install the software, adding a new installation slot as part of the process.

Downloading disk size tools

F5 has created several scripts that are useful if you need to resize your disk volumes as part of the upgrade process. To use these scripts, you must first download them.
  1. Log in to downloads.f5.com.
  2. Navigate to BIG-IQ Centralized Management, v5.4.0, and click I Accept to accept the EULA.
  3. Click F5_Networks_Disk_Size_Tools.zip.
    After a brief pause, the Download Locations screen opens.
  4. Click a download location to start the download.
  5. When the download completes, unzip the file.
    Three files will extract to the folder you designate:
    • addvol
    • imageplan
    • resizevol
Before you can run these scripts, you need to copy them to the device you are resizing.

Check the amount of free disk space on your BIG-IQ VE

  • Before you can use this workflow to check the amount of free disk space on your BIG-IQ VE, you must download the imageplan script from F5.downloads.com. For details on downloading this script, refer to Downloading disk size tools on support.f5.com.
Before you create new slots and size them appropriately, you need to check that there is sufficient physical disk space on the BIG-IQ VE.
  1. Use SSH to log in to your DCD as root.
  2. Use the pvs command to check how much disk space is available for new slots and volumes.
    
    [root@bigiq-console-test-large:Active:Standalone] ~ # pvs
      PV         VG        Fmt  Attr PSize   PFree
      /dev/sda3  vg-db-sda lvm2 a--  498.50g 446.82g
    
    
    The command response tells you how much free disk space is available.

    This device has 446 Gigs of free disk space. That would be more than sufficient for a standard 5.4 install (30G +5G + 5G + 10G = 50G)

If the amount of disk space available is less than the amount you need before you can install your software, you must increase the free space before you can proceed. Refer to the hypervisor vendor documentation for the workflow to increase the amount of available disk space on your VE.

Create correctly sized volumes on the new installation slot

  • Before you can use this workflow to size the volumes on an installation slot, you must download the addvol script from F5.downloads.com. For details on downloading this script, refer to Downloading disk size tools on support.f5.com.
If you are planning to upgrade a BIG-IQ VE, you can use the following steps to create new volumes on the installation slot. The new volumes will be sized correctly for the version you plan to install.
  1. Down load the image file that you plan to install from downloads.f5.com.
  2. Use SSH to log in to your DCD as root and copy the image file to the /shared/images folder.
  3. Use the addvol script to create the filesystems defined in the image plan for the software you plan to install.
    The script creates the correctly sized volume, but does not install any software. In this example, the image file for BIG-IQ version 5.3.0 is used.
    
    [root@bigiq-test:Active:Standalone] ~ # ./addvol HD1.2 /shared/images/BIG-IQ-5.3.0.0.0.1119.iso

      set.2.root    vg-db-sda -wi-a----   450560.00k
    
    
    The script reads the image plan and creates new volumes for /config, /usr, /var, and /root based on the requirements defined in the plan.

Check the volume sizes on your current BIG-IQ installation

When you upgrade a BIG-IQ VE, you need to know the volume sizes for your current installation, because if any of the volumes have been extended, you must extend the volumes on the installation slot before you upgrade. Otherwise, the install process can result in loss of data. To check the volume sizes of the existing installation, you can use the tmsh command show sys software.

Use the following steps to determine the size of the volumes used by your current BIG-IQ installation.
  1. Use SSH to log in to your DCD as root.
  2. Use the tmsh command show sys software to check the volume sizes of the existing installation.
    
    [root@bigiq-test:Active:Standalone] config # tmsh show sys software

      set.1.root    vg-db-sda -wi-ao---   450560.00k
    
    
    The system response shows you the volume sizes of your current installation. The key volumes with their sizes are listed below:
    • /config (.5G)
    • /usr (3.5G)
    • /var (30G)
    • /root (.5G)
The slot you upgrade to must have volumes that are at least as big as those on the slot your software is currently installed on. This is especially significant if you decided to extend one of the volumes on your current installation. So if your /var volume is extended to 30G, you must have at least that much space on the new slot before you install software.

Increase the size of a disk volume

  • You need to download the resizevol script from F5.downloads.com. For details on downloading this script, refer to Downloading disk size tools on support.f5.com.
  • You need to know the volume names that you want to extend and the size that you want to extend them to.

If you need to increase the volume size of a disk volume on your installation slot so that you can install without losing any data, you can use the resizevol script.

  1. Use SSH to log in to your DCD as root.
  2. Use the resizevol script to increase size of the volume on the new installation slot to the required size.
    The volume sizes required depend on the sizes your current installation uses. See Check the volume sizes on your current BIG-IQ installation on support.f5.com.

    The script extends the size of the volume you enter (/var in this example) to the size you enter (30GB in this example).
Now that the volumes are correctly sized, you can proceed with the installation.

Install BIG-IQ to a new slot

  • You need to download the software image from F5.downloads.com.
  • You need to have correctly sized the volumes on the slot you plan to install the new version on.
You can upgrade BIG-IQ using a tmsh command. The process performs the following steps:
  • Creates a UCS backup from the current system and saves it in the /shared folder.
  • Installs a new BIG-IQ image on a new slot.
  • When the new image is installed on the new slot, it copies that data was saved in /shared into the new database running on the new slot.
  1. Use SSH to log in to your BIG-IQ as root.
  2. Use the tmsh install command to upgrade your software.
    Note: The following example uses the create-volume parameter so the process creates a new slot and then begins installing the software on it.
    
    [root@bigiq-test:Active:Standalone] ~ # tmsh install sys software image BIG-IQ-5.3.0.0.0.1119.iso create-volume volume HD1.2
    
    
    The process upgrades your BIG-IQ and restores the data from the current version.
  3. Once the install is complete, you can use the tmsh show sys software command to check to see that the upgrade was successful and that the /var filesystem is the correct size (30M).
    
    [root@bigiq-test:Active:Standalone] ~ # tmsh show sys software

     set.2.root vg-db-sda -wi-a---- 450560.00k
    
    
Now that the volumes are correctly sized, you can proceed with the installation.
