We have the following error in the dmesg output:

xfs_force_shutdown(sd(8,50),0x8) called from line 1071 of file xfs_trans.c. 
Return address = 0xf91fe4a6
Filesystem "sd(8,50)": Corruption of in-memory data detected.  Shutting down
filesystem: sd(8,50)

I stopped all services that access that partition and tried xfs_repair:

Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
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_repair.  If you are unable to mount the filesystem, then use
the -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 I tried to mount the filesystem again:

mount -LNH1 /export/home/h1 -o logbufs=8,logbsize=65536,usrquota
mount: wrong fs type, bad option, bad superblock on /dev/sdd2,
       or too many mounted file systems


Which showed the following message in dmesg:
XFS: Filesystem sd(8,50) has duplicate UUID - can't mount

What does that mean? Is there a chance I can replay the log anyway? Any hints
will be appreciated. Thanks
