OnLine JFS Version identification.

[Kevin Lamb]

Hi,

I currently have OLJFS installed on HP-UX10.20 but have had problems reducing filesystems online, this I have now found out is due to the current version of OLJFS that I am running.

I believe that it is version 2 but how do I clarify this, I have tried the usual swlist, what, sam etc. but cannot work-out what the current version is, the SW code is B3928AA_APZ.

Also I understand that version 3.3 is the uptodate version; however is this available for 10.20, if not what is the latest version.

Thx

Kev

Hi Kevin,

Use "fstyp" to determine the version of the Online JFS

fstyp -v /dev/vgxx/lvolxx |grep -i version

will return the version number

Ramesh,

Thanks for the info, I have ran this on my machine and this shows the version as 3.

Is this the version of OnLineJFS or the version of the filesystem???

Also what is the current version available for 10.20??

From the patch revision, you can do a search here on the itrc to find the latest revision.

Bill,

I have ran the 'what' command against the fsadm with the following output:
usr/sbin/fsadm:
$Revision: 78.5 $
ic12_r10dav_gs libc.a_ID@@/main/r10dav/libc_dav/bvd_dav/1
/ux/libc/libs/libc/archive_pa1/libc.a_ID

I do not get a Patch level, I assume that this implies that the OnLineJFS has never been patched?

Thx

Hi Kevin,

Yes fstyp will give you the version of the Online JFS, and looks like you haven't installed any patches.

I believe version 3.3 is available for 10.20

Cheers Ramesh,

It looks like I need to get my machine patched, I assume that this would have caused the errors I was getting whilst trying to reduce a filesystem?


Thx

Hi Kevin,

one word of caution online jfs version 3.0 did have some limitations and caused errors while reducing the size of a filesystem, so i would strongly say take a backup before reducing the size, also version 3.3 does a much better job in this regard.

Check out the Release notes for Online JFS 3.3
http://docs.hp.com/hpux/pdf/B3929-90007.pdf

-Good luck

Ramesh,

Thanks for the link, I notice that the doc is for HP-UX 11.00, I assume it is Ok for 10.20??

I have found a patch which corrects file resizing problems (PHKL_18914) which is not installed on my server.

I will check out the patch and see if 3.3 is available on 10.20.

Cheers

Hi Kevin,

You might want to install the
advanced vxfs cumulative patch (PHKL_24066) which has a dependency for PHKL_16751 which has dependencies for
PHCO_12922 PHCO_10826 PHNE_13287 PHKL_16957 PHKL_17013 PHKL_17254 PHKL_17858

You also want the fsadm resize problem patch (PHKL_18914).

Well dealing with patches isn't always the best thing ;-) and if you don't want to install all the patches you can try installing the resize patch (PHKL_18914) but i am sure you are better off installing the cumulative and dependency patches as well.

-Regards
Ramesh

Cheers Ramesh,

I will look at the patches, and try and get some downtime as these will require reboot.


Thanks,

Kev
