ReiserFS errors in /var/log/messages

ReiserFS errors in /var/log/messages

[Dan Oglesby]

I recently started seeing the following message repeating in my 
/var/log/messages file on a server:

kernel: is_leaf: free space seems wrong: level=1, nr_items=39, 
free_space=0 rdkey
kernel: vs-5150: search_by_key: invalid format found in block 5405324. Fsck?
kernel: vs-13070: reiserfs_read_inode2: i/o failure occurred trying to 
find stat data of [11 618208 0x0 SD]

Every day a large filesystem rsyncs to another filesystem for 
backup/redundancy, and it looks like this coincides with the error 
listed above.  It repeats about 13 times every time rsync runs.  It's 
always the same block number.

This filesystem lives on a 3Ware RAID-5 array, and is running a 2.4.20 
kernel from RedHat that we cannot upgrade due to hardware and software 
dependancies.

I'm planning on downloading the latest version of the ReiserFS tools, 
and checking for errors/repairing.

Anyone know what this error means, so I have a better idea of what I'm 
dealing with?  I find it strange that I could have a block error on a 
logical drive (the RAID-5 device).

Thanks...
