What would be the procedure for upgrading XFS filesystems from 32-bit to 64-bit? What damage or issues would arise from accessing XFS fs that was formatted on a 32-bit OS with a 64-bit OS?
To recap, I had some issues with NFS to a fileserver that was recently upgraded. Part of the upgrade was to move to a 64-bit OS. The problems with apps hanging on file access over NFS also occurred on the local machine. At this point I noticed the partition was XFS. Somewhere I recall that XFS is not portable between 32-bit and 64-bit systems. Is this correct?
A run of xfs_check showed nothing wrong and xfs_repair ran successfully.
Found the following on the Ubuntu wiki:
"The journal is currently not 32-bit / 64-bit portable. Before mounting a xfs prevously used on 32-bit linux in 64-bit linux (or different arch) the journal has to be emptied using xfs_repair." -- https://wiki.ubuntu.com/XFS
There is no date on this page.
Leaves me wondering why the system behaves strangely, though.
