Hi Saf,

Yes, If you got some free space left in your volume group.

Check if you have.

# vgdisplay -v /dev/vg00
If you have free extends left.

# umount /home
# lvextend -M new_size_in_MB /dev/vgXX/lvolX
# extendfs -F hfs /dev/vgXX/rlvolX
I suspect you use hfs filesystems, check the output from /usr/bin/fstyp /dev/vgXX/lvolX.

# mount /home

# bdf

Hope this helps,
Robert-Jan

hi,

first check the available space in your vg00.
# vgdisplay vg00
# lvdisplay /dev/vg00/
# lvdisplay /dev/vg00/lvol4 [example]

once you have identity the space. do this:
# lvextend -L /dev/vg00/lvol4 [example]

you must un-mount /home
# umount /home
if not possible, you may have to restart the server in single-user boot.

if able to un-mount, then extend via:
# /usr/sbin/extendfs /dev/vg00/rlvol4 [example]

then mount it up again:
# mount /dev/vg00/lvol4 /home [example]

please reply if you have problem with restarting as single user.

regards.

Hi

Hey check whether you have any free extends are available on the volume group where the /home is been created

vgdisplay -v vgXX (where XX is may be 00 , 02 and so on)

if you have any space available then use follwing procedure

umount /home
lvextend -L (specify size in MB) /dev/vgXX/lvolXX

extendfs -F (specify file system type) /dev/vgXX/rlvolXX

mount /dev/vgXX/lvolXX /home

Hello,

once you have checked there is available disk you can check to see if you have online JFS which means you don't need to unmount the filesystem:

swlist |grep -i onlinejfs

if it is installed then:

#lvextend -L /dev/vg/lvol
#fsadm -f vxfs -b /home

hope this helps

/home is often abused by users so you might want to see which users are occupying the most space:

du -kx /home | sort -rn | more

Then look in the biggest directories to see if there are junk files that can be removed. /home will grow without bounds unless you place some controls on it.

Hi,

Since /home is one of those filesystems that can be unmounted, you can unmount it, do a lvextend / extendfs to increase the size and then remount it. Make sure any users who have home directories in /home or are running any processes from home are logged out and their processes stopped / killed.

If you have online jfs this can be done without unmounting by using lvextend / fsadm and without asking any user to log out.

Hope this helps.

Yes you can extend it online if you have online JFS installed. Please note that you have to free up some space and bring the file system to a little bit less than to extend it alse you will get an error. You can move some files to /var/adm/crash and put them back once FS is extended.
To see logival volume do
#bdf /home
See if space is available in vg00 and on both primary and mirroe disks.
#vgdisplay -v vg00|more
For example if you want to extend /home to new size of 800MB
#lvextend -L 800 /dev/vg00/lvolxx
#fsadm -b 800M /home
If you extend a already mirrored logical volume, the mirror will also get extended automatically.

Hi Saf,

First you should check if you can move/remove some unwanted files from /home
# du -axk /home | sort -nr |more

Incase you find that there are no unwanted files then we have to think on increasing the filesystem.

Take the filesystem backup of /home.

Check the availability of space in vg00
# vgdisplay -v /dev/vg00
If there are free space available.

Without Online JFS.
# shutdown 0
This will bring the server in a single user mode and ensure that all the users are logged out.
# mount -a
# bdf (Check the size of /home, say 500MB)
You want it to be 1 GB
# lvextend -L 1000 /dev/vg00/lvolX
lvolX is the logical volume of /home.
# umount /home
# extendfs /dev/vg00/rlvolX
# mount -a
# init 3

With Online JFS installed,
# lvextend -L 1000 /dev/vg00/lvolX
# fsadm -b 1000M /home

All the best.
