vxfs vxupgrade: Filesystem /usr may not be upgraded to version 4.

Eric Antunes — Fri, 24 Mar 2006 06:44:45 GMT

Hi all,

I have successfuly upgraded all vxfs filesystems to version 4 (for HP JFS 3.3) but vxupgrade gives me the above error with /usr. Any ideia??

PS: can I uninstall JFS 3.1 after having all filesystems in version 4?

Best Regards,

Eric Antunes

Any additional warning/informational/error messages??

What does fstyp -v /dev/vgxx/lvolx (for /usr) say?

I think, you can remove JFS 3.1 afterwards.

Hi Eric,

HPUX version 11.0 ?

WARNING!: You cannot upgrade the following file systems to
version 4 layout:
/ (root) /var
/usr /opt

These file systems are used for system recovery. If you upgrade these file systems to version 4 layout, you may not be able
to boot your system with the 11.0 kernel or with the emergency recovery media.

The HP-UX 11.0 kernel and emergency recovery media were created using an earlier version of JFS that does not
recognize the version 4 disk layout.

Regards,
Robert-Jan

After robert's comment, I think you just can not remove old JFS.

Robert,

HPUX version 11.0 ? YES!

WARNING!: You cannot upgrade the following file systems to
version 4 layout:
/ (root) /var
/usr /opt

I already did it for /var and /opt in the Test/Develpment server (Uuf...): what about now? Can I downgrade??

Downgrade? How?? I think you will have to recreate with version 3. check man page of mkfs_vxfs

Hi Eric,

You can downgrade to version 3, i think that is the best option to do.

The vxupgrade manual says:

"...
You cannot upgrade the root (/)or /usr file systems to Version 4 on an
11.0 system running JFS 3.3 from the Application CD. Additionally, we
do not advise upgrading the /var or /opt file systems to Version 4 on
an 11.0 system. These core file systems are crucial for system
recovery. The HP-UX 11.0 kernel and emergency recovery media were
built with an older version of JFS that does not recognize the Version
4 disk layout. If these file systems were upgraded to Version 4, your
system would fail to boot with the 11.0 kernel as delivered or the
emergency recovery media.
..."

I won't even be able to boot (HP-UX 11.0 with JFS 3.3)??

Hi Eric,

Yes, You are correct. Even the Veritas admin guide says the same

http://docs.hp.com/en/B3929-90011/ch02s01.html

I have never come across this situation before, let us wait for experts advice.

Hi all,

I will create another thread for the mkfs command I'll need to use to recreate the /opt and /var filesystems.

Thanks,
