extend /var from 500MB to 700MB

[Teck Sim]

What are the steps to lvextend /var and /stand?

I did the following:

#lvextend -L 700 /dev/vg00/lvol8

and when I did a bdf, the size of /var remains at 500MB. Did I miss out some of the steps?

I am at HP-UX11
Thanks in advance.

You need to do extendfs too:

# man extendfs
# man fsadm

For changing /stand, the best way is to create a recovery tape and reconfigure the size from that.

[A. Clay Stephenson]

So far you have only extended the lvol; you need to run fsadm or extendfs on the filesystem. The command depends upon the type of filesystem.

The short answer for /stand is that you can't extend it because /stand (and /) must be contigious. The only real answer in that case is to do a make_tape_recovery and re-install the OS using Ignite.

[Martin Johnson]

If /var is an hfs file system you will need to umount it. Unfortunately, you will need to bring the system down and come up in single user mode to do this.

Hi Teck,

The steps are,

# umount /dev/vg00/lvol8
#lvextend -L 700 /dev/vg00/lvol8
# extendfs /dev/vg00/rlvol8
# mount /dev/vg00/lvol8 /var
# bdf

You may have to do this in single user mode.

Hope this helps.

Teck,

You need to run extendfs on the rlvol.

As far as /stand goes, see Clay's input.

If you do it online, after lvextend, you need to run fsadm

#fsadm -F vxfs -b 700000 /var

Hi Teck:

I respectfully suggest that you take some time and read chapter-6 ("Managing Disks and Files") in "Managing Systems and Workgroups: A Guide for HP-UX System Administrators":

http://docs.hp.com/hpux/onlinedocs/B2355-90742/B2355-90742.html

This material will help you now, and next time.

Regards!

Hi Teck


I understand that you ahve got ONLINE JFS installed , all yuo need to do is
extendfs /dev/vg00/rlvol8 and you are good to go.

Teck,

In all cases, you must not expand /stand. Normally, this filesystem holds the current kernel /stand/vmunix and a previous kernel /stan/vmunix.prev which occupy 90-95% of the used space in this file system. You may have some extra vmunix.*. If so, you should clean them up.

Teck,

Another point I'd like to make is all you need to do now for /stand is to run the only command:

# extendfs /dev/vg00/rlvol8

which can be safely run in multi-user mode without unmounting it first.

If you are using Online JFS then check this support document

Without online JFS or with online JFS? What is the correct link? Thanks.

[Teck Sim]

The steps I took:

# /sbin/shutdown
# umount /dev/vg00/lvol8
umount: cannot unmount /var: Device busy.
What's that mean?

Thanks.

[Victor_5]

Try fuser -cu /var, if you sure nobody use it, try fuser -ku /var.

Man fuser for more.

[Helen French]

Again, as anyway you brought the system to single user mode (shutdown), I would restart the system (shutdown -y -r 0) and will bring the system to single user mode (ISL> hpux -is).

There will be still processes running on the file system and that's the reason you are getting a Device busy error. If you reboot the system in single user mode, you won't get any of these issues. Once extended, you can boot in normal mode.

[Fragon]

How about this:
#shutdown -ry 0
Go into single user mode then extend your /var file system.

Teck,

I may not be able to stress enough that you do NOT have to bring your system to single-user mode nor unmount the filesystem in order to extend it.
