use extendfs command

# umount /tmp # lvextend -L 1024 /dev/vg00/lvol4 # extendfs -F vxfs /dev/vg00/rlvol4 # mount /dev/vg00/lvol4 /tmp #bdf /tmp

If you have online JFS installed there is no need to unmount /tmp.

lvextend -L 1024 /dev/vg00/lvol4

fsadm -b 1024m /tmp

Hi ,

Steps :

1] check the if you have JFS online installed on your HP-UX box( Usually post HP-UX 11.23 ,it is by default present)

#swlist |grep -i online

2] If JFS online is installed ,Check if you have enough PE's avaialable under vg00 to extend file system

#vgdisplay -v vg00          (Check for Free PE)

3]If you have enough PE's available , you can extend the file system to that size (Free space = Free PE x PE size)

#lvextend -L <Free space> <logical Volume name>

#fsadm -b Freespace M /tmp

4]Cross check if the space is increased,

# bdf /tmp

Hi all

   This has vxfs. So I tried to unmount /tmp and increase the tmp. But I am getting following error when trying to unmount.

# umount /tmp

umount: cannot unmount /tmp : Device busy

umount: return error 1

Then tried followings and kill processes.

# fuser -ku /dev/vg00/lvol4

/dev/vg00/lvol4:     1287o(root)    1296o(root)    1305o(root)    1317o(root)    2083mo(root)    2075mo(root)    2074mo(root)

# kill -9 1287

Sh: kill :A specified process does not exist

Please let me know how to unmount /tmp with this situation.

Regards

The -k would have killed those processes.  What does "fuser -u /dev/vg00/lvol4" show now?

It is very dangerous to "kill -9" various root processes and you should look up what's running on each of those PIDs.

You may make the system unusable and you have to reboot.  And if you do that, might as well bring it up in single user mode.
