The RH6.1 installer ignores errors mounting filesystems with
On my case, /usr had usrquota and grpquota. Upgrade went on
without errors untill it stoped with not enough disk space
on root partition.
Aparently the kernel lacks quota suport.
This seems severe because if / actually has enough space and
upgrade goes on a totally inconsistent system is generated.
This issue has been assigned to a developer for further action.
I would recommend that you try the updated images that we just
released, as there is a fix there that should solve your problems.
The installer was not mounting partitions which had anything other
than "defaults" in the fstab options field, therefore partitions with
the quota flags were not getting mounted for the upgrade. Reopen this
bug is this does not solve your problem. Check out the errata page
for the latest information about the new boot images
