[Ocfs-users] REGARDING TO DOWNGRAING OCFS FROM 1.0.14-1 TO 1.0.9-12

[Kenichiro Ochi]

Hi, all.

My name is Kenichiro Ochi, in Oracle Japan Support.

Customer examines upgrading OCFS from 1.0.9-12 to 1.0.14-1.
And customer asked us a question about the way of downgrading to 1.0.9-12.
(customer presumes a case in case after the upgrade.)

We tested the following...
0.After the upgrade
1.umount OCFS volume on all nodes
2.uninstall rpm (V1.0.14-1)
  # rpm -e ocfs-tools-1.0.10-1
  # rpm -e ocfs-2.4.9-e-1.0.14-1
  # rpm -e ocfs-support-1.0.10-1
3.install rpm (V1.0.9-12)
  # rpm -ivh ocfs-support-1.0.9-12.i686.rpm
  # rpm -ivh ocfs-2.4.9-e-1.0.9-12.i686.rpm
  # rpm -ivh ocfs-tools-1.0.9-12.i686.rpm

Actually, there was no problem in the behaviour with this procedure.

And, I comfirmed this README.
(http://oss.oracle.com/projects/ocfs/dist/files/README)

This readme says "Running a mix of nodes with 1.0.9 or earlier 
and 1.0.14 is NOT recommended."
But, as for the downgrading from 1.0.14-1 to 1.0.9-12, 
there is no description in this document.

Expert, Is there a problem with the above procedure?

I would appreciate it if I could receive feedback on it 
at your earliest convenience.

Since I'm not in the mailing list, please reply directly back to me.
Thank you in advance.

Thanks
Kenichiro
