Upgrade RHEL5 to RHEL6 with XFS data partition
I am getting ready to upgrade our file server from RHEL5 to RHEL6 so I can resolve a 16 group limitation bug related to NFS.
See here: https://xkyle.com/solving-the-nfs-16-group-limit-problem/
I am curious if anybody has upgraded a system with an XFS filesystem from RHEL5 to RHEL6 and mounted the XFS filesystem okay in the new system. I've done that before with ext3/4 partitions, but never XFS. I just wanted to know if anybody has done it first since if something goes wrong, I get to spend like 3-4 days restoring 24TB from tape.
The current filesystem layout is below:
/ EXT3
/boot EXT3
/exports/projects 26TB XFS
/exports/analysis 100GB XFS
Thanks,
Roy
