castro_2 — Tue, 02 Sep 2003 19:59:05 GMT

I have installed Online JFS
B3929BA B.11.00 HP OnLineJFS (Advanced VxFS)

"Logical volume /dev/vgXX/lvolX is currently mounted on /mountpoint and could not be umnounted."
Is like don??t have Online JFS, I use Ignite to installed this.
Thanks

1) Is the filesystem in question a vxfs or hfs filesystem?

2) Have you licensed OnlineJFS? OnlineJFS 3.3 on 11.0 requires run-time licensing in order to function.

Did you remember to use fsadm instead of extendfs?

Are you sure Online JFS is installed?

swlist -l product | grep -i JFS

swlist | grep -i JFS

swverify \*

See Clay's response and have a read through the manual. It is almost surely a licensing issue.

Hi,

Mark is correct.

lvextend -L 500 /dev/vg00/lvol20
fsadm -b 500M /mountpoint

instead of lvextend + extendfs.

regards,
Thierry.

What command are you using to extend the filesystem? For online JFS you should be using the fsadm command:

fsadm -b new_block_size /your_mount_point

Good luck.

Hi:

Product B3929BA represents the 3.1 version of Online JFS and does not need the license activation like B3929CA -- the 3.3. version.

Verify that you have the 'vxadv' kernel driver installed:

# grep -i vxadv /stand/system

Regards!

...JRF...

I think this is the problem

# grep -i vxadv /stand/system
nothing.

I supose that I want to reinstall the Online JFS
Thanks

I have tried that grep command offered to you on my boxes which all have JFS enabled and I get a null response as well... Are you sure htat grep command is correct???

Also, if it is a licenseing issue try this command...

# /sbin/fs/vxfs/vxenablef -a ## to activate a JFS license

To check:

# /sbin/fs/vxfs/vxenablef ## to check if it is loaded???.
System is licensed for features

I don??t have this command
/sbin/fs/vxfs/vxenablef
Thanks

Todd McDaniel_1 — Wed, 03 Sep 2003 17:52:24 GMT

I belive this is an 11.i difference... When I look for JFS I don't even see that patch referenced above... So someone with 11.0 boxes will have to help from here...

I might reinstall just to make sure you did it, with:

-x reinstall=true

If you also have mirroring I would make sure to install mirror-ux as well.

Post back when you get a resolution.

Castro,

I remember that I had this problem a while ago, when I swcopy-ed "Adv. Online JFS" AND a couple of patches into a single depot for installation in ONE go. Though it did install the Online JFS but the driver was not in the Kernel. There must have been a bug in generating the kernel with those kernel changes required by the patches.

Easiest solution is to add the driver into the kernel like JRF said.

Bernhard

Hi Castro,

Sorry for my delayed response. This is my first time on in quite a while.

This problem is specific to OnlineJFS 3.1 on 11.0. JFS 3.3 on 11.0 and above uses a licensing scheme.

I do not recommend simply adding the vxadv driver into your kernel. The reason that it is missing is that the OnlineJFS product should be patched before enabling the driver as there are some crucial bugs in the OnlineJFS product that needs to be fixed before enabling the driver.

If you go back and look at the swinstall.log file, you should see a message in the log that tells you that the product is installed, but disabled. It should instruct you that you need to reinstall PHKL_18543 (which is probably already installed).

The reason for this the OnlineJFS product installs unpatched modules.

***IMPORTANT NOTE*** Never, ever, ever install PHKL_18543 with the reinstall=true option. Just use a default install, even if PHKL_18543 is already installed. Swinstall will only patch the OnlineJFS modules that were not present with PHKL_18543 was initially installed.

Once PHKL_18543 is installed again, then install your other important OnlineJFS patches.
