Hi David,

that's something I am not sure about, I have used the newest xfs_repair
tools and it found and repaired some inodes. And for about two months
there weren't any crashes.

The main workload of this machine is high samba activity with few
clients but many IO tasks (i.e. Photoshop batch processing on many 3-6
MB Images). The XFS Partition is on an easy-RAID 16 P. Other Partitions
are EXT3. There are also 2 iSCSI-Partitions with XFS. For Hardware
Information, see below.
After the crash I did an xfs_repair and it found corrupt directory inode
and moved it to lost+found as " 254474253".
Normally the Kernel freezes/hangs completely, but I found two new
Kernel BUG (see below) in the log-messages (without a freeze), the
corresponding java-program was building an lucene-index from a
mysql-database.
It seems that xfs_repair (2.8.10), did not find all of the errors of the FS.
Is there a way to be sure that the FS is clean?

There weren't any I/o errors.
