I'm new to xfs and was wondering how to increase the size of /var and /home, I'm guessing xfs does not simply increase in size as needed…
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 ext3 4.0G 418M 3.6G 11% /
none devtmpfs 4.2G 205k 4.2G 1% /dev

Best Answer
You're using LVM, which is good. As long as the logical volume within which
/var
and/home
reside is bigger than they are now, you can do the resize withxfs_growfs
.First make sure the logical volume you're using for the two partitions is bigger than
3.7G
(for/dev/mapper/vg00-var
) and2.5G
(for/dev/mapper/vg00-home
):bash$ lvdisplay <partition> | grep 'LV Size'
If the logical partition is bigger (so your FS has room to grow), you're all set.
If it's not, then you need to look at the physical volume group which contains the above logical volume, and make sure there is enough space in there to grow the logical volume first.
