HP-UX 11.22: lvextend

[Mike Linger_2]

I'm trying to install an application through SAM.

Initially, it looks like /opt was too small.

I've increased /opt to 3.5 GB (an increase of about 3 GB). I only needed an extra 200 MB, but I believe in overkill.

SAM reports the new volume size as 3504 MB in the logical volume manager. However, bdf reports that the volume is still small. Why?

I started with the GUI in SAM and increased the logical volume to 2000 MB. bdf still reported no change.

Then, I used the lvextend command:
lvextend -L 3000 /dev/vg00/lvol6

The volume manager in sam detected this increase, but bdf still doesn't notice the change.

Finally, I used sam to increase to 3500 MB. bdf still doesn't notice.

The GUI in sam reports that there is still not enough space to install my application. it looks like this installation application relies on bdf.

You need to run extendfs

sam should have done that for you though, there was probably an error.

extendfs -F vxfs /dev/vg##/rlvol6

as root. At least you'll see the error, whatever it is.

fsadm with OnlineJFS.

Do you have Online JFS? If so:

lvextend -L 2500 /dev/vg00/lvol4
^
|-- lv_size

c. fsadm -b 2560000 /opt

Or:

d. fsadm -b 2500m /opt

[Mike Linger_2]

Looks like fsextend requires that I unmount /opt.

Looks like I can't unmount /opt
device busy. I'm the only user on the system.

Hi,

Check with fuser or losf if some application is using /opt. Stop the application and try unmounting again.

Maybe you didnt see Stuart's post above ...

IF you JFS online you can use fsadm to extend a mounted filesystem...

fsadm -b {extents*4096}

extendfs is valid only if you dont have JFSonline OR if you can umount the filesystem... but I wouldnt umount it if you can use fsadm.

Hi,
In your case only LV is extended but not FS.So u have to extend FS also.

If u have JFS online installed on your machine, you can use fsadm -b . Otherwise you have to unmount the FS and run extendfs .
Then u can see new size in bdf also.

Yes extendfs does require umount

If you are the only user on the system, you MIGHT be able to clear users as follows:

fuser -cuk /opt

That might blow you out of the system or affect applications, so be careful.

This assumes you do not have OnlineJFS.

That seems to be the case.

Mike, if the server does not have online-JFS installed I suggest you to boot the server into single user mode and expand /opt.

[Mike Linger_2]

I don't have the JFS.

The fuser command did not unmount /opt

I've never seen this behavior before. I'm reinstalling the OS. This time, I will extend the volumes first.

[Bernhard Mueller]

You do not have to reinstall, just boot into single user mode and run
# vgchange -a y vg00
(assuming your root vg is vg00)
# extendfs -F vxfs /dev/vg00/rlvol6
(asssuming /opt is mounted from /dev/vg00/lvol6)


to boot into single user mode, connect to lan/web/serial console (whatever you have),
enter
# shutdown -r -y 0
interrrupt boot at the BCH (where it tells you that you have 10 seconds to interrupt the boot process), enter
bo pri
question "interact with ISL?" answer

at ISL>
enter
hpux -is

vgchange and extendfs as above
# mount -a
# bdf
# reboot

I guess from Mike's post he is Loading a new OS and Application on a new server...

Mike maybe you can elaborate.
