Hi,
I am using Marvell git (2.6.30-rc3) with Jaunty, formatted my sda1 to XFS with not problem, copy content to it done with no problems.
Then I umounted it and tried to mount it again, this is what I get:
mount: /dev/sda1: can't read superblock
When running xfs_check I get this:
xfs_check /dev/sda1
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed. Mount the filesystem to replay the log, and unmount it before
re-running xfs_check. If you are unable to mount the filesystem, then use
the xfs_repair -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
So then I ran xfs_repair:
root@plugme:~# xfs_repair /dev/sda1
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...

Only xfs_repair with "-L" option fixed the XFS mount:
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
destroyed because the -L option was used.
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...

- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
Phase 5 - rebuild AG headers and trees...
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
done
Now I can mount it and see my stuff, monting and umounting it works fine until I copy content to the partition.
Is there some mkfs/mount option that fixes this? I see some XFS EABI related issues on Lenny too.
When creating the XFS with log on another device solves this problem:
mkfs.xfs -l logdev=/dev/sda2,size=10000b /dev/sda1
mount /dev/sda1 /mnt/disk/ -o logdev=/dev/sda2
