syslogd kernel: EXT3-fs error

Hi,

I recently inherited a server that has been routinely generating the following syslog entry:

kernel: EXT3-fs error (device md(9,3)): ext3_free_blocks: Freeing blocks not in datazone - block = 6521216, count = 1

I've done a little research and some sources recommend running an fsck. Does anyone else have recommendations for this? This system has a RAID. Does that affect how I need to run fsck? Can fsck be run on the server if it's in production with no worries? The previous owner is unavailable for advice or history.

Thanks in advance.

Thanks for the response. Do you have any recommendations on how to proceed? I need help determining if fsck is the correct way to resolve the error above.

Running fsck would be the best option to analyze the corruptions on your ext3 partition. Your RAID setup wont affect fsck. Your best option would be to run fsck on the partition in read-only mode using "fsck.ext3 /your/device -n" and see if any errors are found. To fix it, replace the -n with -p.

Also, since ext3 is a journaling filesystem, it does a good job on its own in avoiding corruptions in the filesystem so your problems could indicate a failing harddrive. You can use the -c option with fsck to scan the disk for bad blocks which would be marked in the filesystem to avoid use. This will make your drive usable but if any such bad blocks are found, I would concider buing a replacement
