The article describes the steps to extend the / lvm partition on a FortiSIEM node.
Scope
FortiSIEM
Solution
Using Hypervisor (for example, ESX), add a new disk of the size needed (25G or 50G) to the FortiSIEM VM.
Login to the FortiSIEM CLI and run the 'lsblk' command and find the name of the new hard disk added.
For example:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 25G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 24G 0 part ├─rl-swap 253:0 0 2.5G 0 lvm [SWAP] └─rl-root 253:1 0 21.5G 0 lvm / sdb 8:16 0 100G 0 disk ├─sdb1 8:17 0 22.4G 0 part [SWAP] └─sdb2 8:18 0 68.9G 0 part /opt sdc 8:32 0 60G 0 disk └─sdc1 8:33 0 60G 0 part /cmdb sdd 8:48 0 60G 0 disk └─sdd1 8:49 0 60G 0 part /svn sde 8:64 0 61G 0 disk /data
Create a Physical Volume using the new disk.
pvcreate <new_disk_name>
For example:
pvcreate /dev/sdx
Run the following command and note the current volume group (VG) size.
vgdisplay
For example:
--- Volume group --- VG Name rl System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size <24.00 GiB PE Size 4.00 MiB Total PE 6143 Alloc PE / Size 6143 / <24.00 GiB Free PE / Size 0 / 0 VG UUID Oo8x27-PLgU-NMLg-1BQ8-hw5U-2boo-dMb0Kl
Add a physical volume to the existing volume group 'rl':
vgextend rl <new_disk_name>
Note the free size (Free PE / Size) in volume group 'rl':
vgdisplay
Extend the / lvm partition:
lvextend -l +100%FREE /dev/rl/root
Extend file system of / lvm partition:
xfs_growfs /dev/rl/root
Run the 'df -h' command to verify the size of / partition.
