LVM snapof option...

[Jonathan Caplette_1]

Hi guys,

I'm trying to do a snap clone of my LVM filesystem. I do this everynight, but tonight I have a problem with it... I've just install the patch bundle Quality Pack from Dec. 2006.

Here's what I do everynight:

mount -F vxfs -o snapof=/oradata21 /dev/vg50DC/lvCLONE1 /clone/oradata21


Here's the error that I got:

mount: You don't have a license to run this program

It's the first time I've this error, and it happened the first time I run the snap after the Quality Pack update...

Any idea what can cause this... I'm not a pro with the snapof option...

Regars
Jonathan

First of all, snapof mounts have nothing to do with LVM; they are a feature of OnlineJFS (vxfs) file systems and would work equally well under LVM, VxVM, or even whole disks as containers of filesystems. Your problem almost certainly is a result of your reboot. Your were running on an expired OnlineJFS license and reverted to the standard JFS licensing. Tons of people have had your problem since June of this year. Your were sitting on a ticking time bomb and didn't know it. Do a search on expired OnlineJFS and you should find tons of hits with the solution.

HP has new patch(LVM/onlinejfs)with respect to this problem.

Hi Jonathan:

As noted, your OnlineJFS license expired June 24th since is was originally, and erroneously, provided as a "demo" license.

Although HP *did* announce the problem about a year or so before the expiration data, it seems many folks either didn't heed or didn't see the notice. Due to to the large number of misses, this advisory was recently issued:

http://www.hp.com/softwarereleases/releases-media2/notices/June28_v12.pdf

Note the instructions for reinstallation therein. *No* reboot will be necessary if you follow them.

Regards!

Yes, this is a known bug and affects systems that installed Enterprise or Mission Critical Environments where OnlineJFS was included on the CD. Prior to Sep 2005, some of the CDs has a demo or trial license imbedded in the code which expired last month. You would NEVER see this problem until you use one of the OnlineJFS features like fsadm -b or snapshot, etc. To immediately see if you have the problem:

/sbin/fs/vxfs/vxenablef

If this reports that you have no license, you have the problem. The fix (as explained by the previous HP website) is to reinstall the product from the MCOE or Enterprise DVD dated Sep 2005 or later, Without this DVD, your only choice is to order the media from HP. You'll need your software support agreement number.

I re-installed OnlineJFS with my MCOE December 2006 Cd's!!
