Well, there were several recent reports of ext3 problems, and two reports had the same message. Two of them definitely were also using RAID (RAID 1 and RAID 5). See thread starting at: http://marc.theaimsgroup.com/?l=linux-kernel&m=102070252100762&w=4 and also an older (but still 2.4.18) thread at: http://marc.theaimsgroup.com/?l=ext3-users&m=101041709332435&w=4 No mention of RAID in the second thread. I can't find the other messages to which I refer in the first thread about "several other reports of corruption with ext3 on MD RAID". Neil, you posted in another message the text from the corrupt directory blocks, which matches with the second thread where the bad data looked like filenames (the first thread's directory data doesn't decode to anything useful in ASCII).
