... and one person has said it was fixed in 2.6.28-rc8, and at least
one, possibly two people have reported that it has been fixed in
2.6.29.  I think you're running some version of 2.6.28 or 2.6.28.y,
correct?

Had the problem with 2.6.28, 2.6.28.4 and 2.6.29-rc6. After yesterday's crash I've upgraded to 2.6.29. For completeness' sake, my ext4 RAID had been created from scratch, not upgraded from ext3.

Should I still apply the oneliner you posted yesterday on 2.6.29?

In the meantime I've tried mkfs -S, this complained about "File exists while trying to create journal". fsck -y is running (has been for a few hours) and appears to cycle through

 Group xx inode table at yy conflicts with some other fs block. Relocate?
 [repeated enough times to overflow my xterm's scrollback buffer]
 Root inode is not a directory. Clear?

We'll see what I can fish out of the lost+found once it's done.
