Since your /var
is an LVM logical volume, you could increase its size by using another disk’s space. However, you are using /dev/sdb
as an unpartitioned disk. You should:
- Back up the data from
/dev/sdb
somewhere,
- partition your
/dev/sdb
drive,
- restore the original data to one partition and mount it as
/mnt/data
and
- use another partition as a physical volume which your logical volume
/var
can utilize.
Alternatively, you can make /mnt/data
a logical volume, too. In this case, the physical volume on /dev/sdb
could be either a partition or the whole unpartitioned disk. I’d still prefer to create a partition there, even a single one. The partition table does not take much space and the drive will have a more flexible setup – you can see the difference right now.
