Startup script:

^ OpenVZ

^^ Add disk space to VE

First, resize logical volume:

.pre
root@koha-hw:~# df -h /vz/
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg-vz 99G 20G 79G 21% /vz

root@koha-hw:~# vgextend -L +80G /dev/vg/vz
vgextend: invalid option -- L
Error during parsing of command line.

root@koha-hw:~# lvextend -L +80G /dev/vg/vz
Extending logical volume vz to 100.00 GB
Logical volume vz successfully resized

root@koha-hw:~# resize2fs /dev/vg/vz
resize2fs 1.40-WIP (14-Nov-2006)
Filesystem at /dev/vg/vz is mounted on /vz; on-line resizing required
old desc_blocks = 2, new_desc_blocks = 7
Performing an on-line resize of /dev/vg/vz to 26214400 (4k) blocks.
The filesystem on /dev/vg/vz is now 26214400 blocks long.

Then, take a look how much space does VEs take:

.pre
root@koha-hw:~# vzlist -o veid,status,ip,hostname,diskspace,diskspace.s,diskinodes,diskinodes.s
VEID STATUS IP_ADDR HOSTNAME DQBLOCKS DQBLOCKS.S DQINODES DQINODES.S
