I suppose looking at a couple of those could verify if it's really just NFS caching related corruption or something else.
Okay, I will post results when I have them.
I found a lot of files that hat null bytes in them, but no other problems (which could be due to the fact that my uidlist checking script isn't all that great).
I have put two corrupted dovecot-uidlist and the corresponding log files, and the check script up at http://www.topfen.net/user/ul/dovecot/. I hope that's enough data.
OK. That just confirms file size caching issue:
- Server A read and cached file's size
- Server B recreated it as smaller file
- Server A wanted to append new entry to the file, but used the cached file size so it wrote past the end of file, causing those NUL bytes in the middle.
