There is one HP-UX server running B.11.00.
I have checked if online JFS has been installed using following command.
#swlist | grep -i online
OnlineDiag B.11.00.20.09 HPUX 11.0 Support Tools Bundle, Mar 2002
My Questions:
1)Could you please clarify me if online JFS has been installed or not?
2)Is it possible with above bundle only , can I increase filesystem size on fly?
3)Or Is it must that I have ot unmount the filesystem and then increase the size and then mount the filesystem again?
Solved! Go to Solution.

SolutionIn HP-UX 11.00, the swlist line for OnlineJFS looks like this:
B3929BA B.11.00 HP OnLineJFS (Advanced VxFS)
(As a HP-UX sysadmin, you really should know what OnlineDiag is, and that it obviously isn't the same thing as OnlineJFS.)
2.) No, you can't.
3.) Yes.
Example:
lvextend -L
umount /dev/vgSOME/lvolX
extendfs -F vxfs /dev/vgSOME/rlvolX
mount /dev/vgSOME/lvolX

Re: Can I increase size of the file system with out unmount only if online diag has been installed.
# swlist |grep -i online
B3929CA B.11.11 HP OnLineJFS
2) No - you need to run extendfs which cannot be run on a mounted file system.
3) See #2
And the title of your thread says online diag - online diagnostics is, obviously, something else entirely.

Re: Can I increase size of the file system with out unmount only if online diag has been installed.
The 'OnlineDiag' bundle is *not* the OnlineJFS one!
If you don't have OnlineJFS (which it appears you don't) then you must unmount the filesystem that you want to resize; expand it; and then re-mount it.
To unmount a filesystem, of course, no processes can be using it. While you might use 'fuser' to kill the processes preventing the filesystem from being unmounted, it is often cleaner and easier to boot into single-user mode; use the commands in '/sbin' to perform your LVM and 'extendfs' actions; and then reboot to resume normal operations.
Lastly: You have a recently growing number of questions you have asked without any point assignment whatsoever:

Please take the time to evaluate these threads and assign points appropriately.
