Re: increase the volume

If you mean capacity, take a look at the man page for vgextend, lvextend and extendfs. The examples section of lvextend shows pretty clearly the steps you need to follow.

Re: increase the volume

Find out what LV this filesystem resides on.

# bdf /home

Then look if you still have sufficient free PEs in vg00 (assuming that /home's LV is part of vg00)

# vgdisplay vg00|awk '/PE Size|Free PE/{print$NF}'|xargs printf "echo \$((%d*%d))\n"|sh

Decide how much you need to grow the FS
and extend the LV

either giving the new end size in MB

# lvextend -L 512 /dev/vg00/lvol5

or in LEs
(e.g. grow by 24 LEs)

# lvextend -l $(($(lvdisplay /dev/vg00/lvol5|awk '/Current LE/{print$NF}')+24)) /dev/vg00/lvol5

Verify the LVs new size

# lvdisplay /dev/vg00/lvol5|awk '/LV Size/{print$NF}'

If you have OnlineJFS grow the mounted filesystem


# fsadm -F vxfs -b $(lvdisplay /dev/vg00/lvol5|awk '/LV Size/{print$NF}')m /home

If you lack OnlineJFS you need to unmount /home
which probably requires your user's to logout.
Check if FS is in use

# fuser -c /home

Are you using vxvm
