This KB explains about how to increase the storage space /opt/vmware/support partition on SRM Appliance.
Environment
VMware Live Site Recovery 9.0.2
Resolution
Follow the below steps to increase the SRM appliance /opt/vmware/support partition space on SRM appliance.
1. Ensure there is good backup of the SRM appliance and ensure there is no snapshot in the SRM appliance.
2. Connect to SRM appliance via putty session and run df -h to check the current space utlization for /opt/vmware/support partition on SRM Appliance.
Example : admin@srm01-dr [ ~ ]$ df -hFilesystem Size Used Avail Use% Mounted ondevtmpfs 4.0M 0 4.0M 0% /devtmpfs 5.9G 40K 5.9G 1% /dev/shmtmpfs 2.4G 744K 2.4G 1% /runtmpfs 4.0M 0 4.0M 0% /sys/fs/cgroup/dev/sda5 14G 2.9G 9.9G 23% /tmpfs 5.9G 128K 5.9G 1% /tmp/dev/sda3 230M 33M 185M 16% /boot/dev/mapper/support_vg-support 17G 113M 16G 1% /opt/vmware/support/dev/sda2 10M 2.1M 8.0M 21% /boot/efi/dev/loop0 365M 49K 345M 1% /opt/vmware/support/logs/srm/SRAstmpfs 1.2G 0 1.2G 0% /run/user/666
3. Run lsblk command to list the disk parition and mount points of SRM appliance. admin@srm01-dr [ ~ ]$ lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTSloop0 7:0 0 400M 0 loop /opt/vmware/support/logs/srm/SRAssda 8:0 0 16G 0 disk├─sda1 8:1 0 4M 0 part├─sda2 8:2 0 10M 0 part /boot/efi├─sda3 8:3 0 256M 0 part /boot├─sda4 8:4 0 2G 0 part [SWAP]└─sda5 8:5 0 13.7G 0 part /sdb 8:16 0 17G 0 disk└─support_vg-support 254:0 0 17G 0 lvm /opt/vmware/supportsr0 11:0 1 2.3G 0 rom
4. Running pvs command on SRM appliance to display formatted information about Physical Volumes (PVs) within Logical Volume Manager (LVM).root [ /home/admin ]# pvs PV VG Fmt Attr PSize PFree /dev/sdb support_vg lvm2 a-- <17.00g 0
5. Connect to vSphere Web client and select your SRM appliance and increase the space of Hard disk 2 from 17 GB disk space to 20 GB.
Before increasing the disk space on SRM appliance the Hard disk 2 disk space shows 17 GB
After Increasing the Hard disk 2 space by 3 GB i.e. from 17 GB to 20 GB we can now see the updated space as 20 GB.
6. Run pvresize /dev/sdb to increase the space for /dev/sdb partition is mapped to /opt/vmware/support in SRM appliance. root [ /home/admin ]# pvresize /dev/sdb Physical volume "/dev/sdb" changed 1 physical volume(s) resized or updated / 0 physical volume(s) not resized
7. Reboot the SRM appliance.
8. Run pvs command on SRM appliance to check if you are able to see the PFree showing up newly added space i.e. in this example we added 3 GB additional space so we should see 3GB under PFree section in the below output. root [ /home/admin ]# pvs PV VG Fmt Attr PSize PFree /dev/sdb support_vg lvm2 a-- <17.00g 0root [ /home/admin ]#
9. If the PFree space is not updated in this case we need to re-run "pvresize /dev/sdb" again and then run pvs command to validate whether the PFree is showing newly added space i.e. 3 GB.root [ /home/admin ]# pvresize /dev/sdb Physical volume "/dev/sdb" changed 1 physical volume(s) resized or updated / 0 physical volume(s) not resizedroot [ /home/admin ]# pvs PV VG Fmt Attr PSize PFree /dev/sdb support_vg lvm2 a-- <20.00g 3.00groot [ /home/admin ]#
10. Then run lvdisplay to see the size of each logical volumes and LV Path will display the name of the logical volume. In this example we are increasing the space for /dev/support_vg/support logical volume.
Before exapanding the logical volume the LV Size of /dev/support_vg/support is 17.00 GiB.
For example : root [ /home/admin ]# lvdisplay --- Logical volume --- LV Path /dev/support_vg/support LV Name support VG Name support_vg LV UUID GZiuSw-9Dwc-xxxx-xxxx-xxxx-xxxx-D2Xobi LV Write Access read/write LV Creation host, time photon-machine, 2024-06-03 02:15:30 +0000 LV Status available # open 1 LV Size <17.00 GiB Current LE 4351 Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:0
11. Now expand the space /dev/support_vg/support using the lvextend -l +100%FREE to increase 100% of the available free space which is 3 GB.root [ /home/admin ]# lvextend -l +100%FREE /dev/support_vg/support Size of logical volume support_vg/support changed from <17.00 GiB (4351 extents) to <20.00 GiB (5119 extents). Logical volume support_vg/support successfully resized.
12. Now Run the lvdisplay command to see the updated logical volume space for /dev/support_vg/support.root [ /home/admin ]# lvdisplay --- Logical volume --- LV Path /dev/support_vg/support LV Name support VG Name support_vg LV UUID GZiuSw-9Dwc-xxxx-xxxx-xxxx-xxxx-D2Xobi LV Write Access read/write LV Creation host, time photon-machine, 2024-06-03 02:15:30 +0000 LV Status available # open 1 LV Size <20.00 GiB Current LE 5119 Segments 3 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:0
13. To finalize the change, we must run resize2fs /dev/mapper/support_vg-support. This command expands the file system into the newly allocated 3 GB of free space, bringing the total usable capacity for /opt/vmware/support from 17 GB to 20 GB.
Before running the resize2fs /dev/support_vg/support command we can see the /opt/vmware/support size shows are 17Groot [ /home/admin ]# df -hFilesystem Size Used Avail Use% Mounted ondevtmpfs 4.0M 0 4.0M 0% /devtmpfs 5.9G 40K 5.9G 1% /dev/shmtmpfs 2.4G 752K 2.4G 1% /runtmpfs 4.0M 0 4.0M 0% /sys/fs/cgroup/dev/sda5 14G 2.9G 9.9G 23% /tmpfs 5.9G 128K 5.9G 1% /tmp/dev/sda3 230M 33M 185M 16% /boot/dev/mapper/support_vg-support 17G 106M 16G 1% /opt/vmware/support/dev/sda2 10M 2.1M 8.0M 21% /boot/efi/dev/loop0 365M 49K 345M 1% /opt/vmware/support/logs/srm/SRAstmpfs 1.2G 0 1.2G 0% /run/user/666
The resize2fs command completed the task of growing the logical volume /dev/support_vg/support from 17G to 20G.root [ /home/admin ]# resize2fs /dev/support_vg/supportresize2fs 1.46.5 (30-Dec-2021)Filesystem at /dev/support_vg/support is mounted on /opt/vmware/support; on-line resizing requiredold_desc_blocks = 2, new_desc_blocks = 2The filesystem on /dev/support_vg/support is now 5241856 (4k) blocks long.
After running the resize2fs /dev/support_vg/support command we can see the /opt/vmware/support size shows are 20Groot [ /home/admin ]# df -hFilesystem Size Used Avail Use% Mounted ondevtmpfs 4.0M 0 4.0M 0% /devtmpfs 5.9G 40K 5.9G 1% /dev/shmtmpfs 2.4G 752K 2.4G 1% /runtmpfs 4.0M 0 4.0M 0% /sys/fs/cgroup/dev/sda5 14G 2.9G 9.9G 23% /tmpfs 5.9G 128K 5.9G 1% /tmp/dev/sda3 230M 33M 185M 16% /boot/dev/mapper/support_vg-support 20G 106M 19G 1% /opt/vmware/support/dev/sda2 10M 2.1M 8.0M 21% /boot/efi/dev/loop0 365M 49K 345M 1% /opt/vmware/support/logs/srm/SRAstmpfs 1.2G 0 1.2G 0% /run/user/666
