Kernel is stock except for ppskit-lite patches. This is the usually-not-mounted emergency rescue partition which contains disaster recovery tools. Thus, the somewhat paranoid data integrity settings. The FS just filled up as I was doing the every-few-months update. Filesystem 1K-blocks Used Available Use% Mounted on /dev/md1 432312 425732 0 100% /boot I'm currently copying a raw device snapshot which I can make available to anyone who promises not to go grepping for secrets on it. I don't think there are any, but hunting through the whole image and maybe zeroing a few data blocks is a bit of a PITA. Anyway, thanks for what has usually been a very reliable file system! I hope there's enough info here to find the problem. Here's the tune2fs -l output.
