expand /tmp

Nobody's Hero — Wed, 19 Oct 2005 06:33:06 GMT

If I have free extents in /dev/vg00, can I expand /tmp without using ignite? I dont want to use ignite, even though that is my usual method.

Yes, you can do it .. first kill all user processes in /tmp

# fuser -ku /tmp

then, you can extend it.

Hello Robert

use this:

init 1 (Attention !)
login ...

umount /tmp
lvextend -L 600 /dev/vg00/lvol4
extendfs /dev/vg00/rlvol4
mount /tmp

init 4

Generally speaking, it's going to be more effective to reboot and go into single user mode to make sure that /tmp is available to be extended.

Hi robert,

Yes you can, but try to do it in single user mode.

hI Robert,

The easits solution, is to boot in single mode

# lvextend ....
# extendfs .....

# mount -a

# shutdown -r -y now

fsadm -d -D -e -D /mount_point
lvextend -L 500 /dev/vgXX/logical_volume_name
fsadm -b newsize_in_fs_blocks /mount_point

Like:

fsadm -b 51200 /mount_point

If you are having onlinJFS then you don't need umount and mount fs during extend operation.

Refer "Increase the size of a file system existing on a logical volume." in lvextend man page.

# lvextend -L 400 /dev/vg06/lvol3

Unmount the file system.

# umount /dev/vg06/lvol3

Extend the file system to occupy the entire (larger) logical vol

# extendfs /dev/vg06/rlvol3

Remount the file system.

# mount /dev/vg06/lvol3 /mnt

In this umount and mount operation is not needed for online JFS.

hth.

In single user mod
umount /tmp
lvextend -L Newsize /dev/vg00/lvol4
extendfs /dev/vg00/rlvol4
mount /tmp

with online JFS

lvextend -L Newsize /dev/vg00/lvol4

umount /dev/vg00/lvol4

extendfs /dev/vg00/rlvol4

mount /dev/vg00/lvol4 /tmp
