Hi, Maybe I've some more 2.4.3 badness: I just decided to restore one message, and copied it from the archive. Unfortunately, I didn't copy properly, so the ownership was root instead of cyrus. I then ran a # sudo -u cyrus /usr/local/cyrus/bin/reconstruct user.bla user.bla: System I/O error System I/O error Hmm, allright, so I ran it with a truss (like strace for FreeBSD) to give me a bit more verbosity, and I realized I should chown. But then: # chown cyrus 22003. # sudo -u cyrus /usr/local/cyrus/bin/reconstruct user.bla fatal error: can't read mailboxes file Ehm, that's bad. # sudo -u cyrus /usr/local/cyrus/bin/ctl_mboxlist -d fatal error: can't read mailboxes file Uhoh! And then I looked at mailboxes.db: It looks like part completely rewritten, including the skiplist header, and the first line now said: user.bla: System I/O error System I/O error Oops? Fortunately I had a recent copy, I just decided to make a tarball of /var/imap after realizing I probably lost (a recent backup of) seen state (related to other thread) because /var/imap is not on ZFS :-S Regards, Paul ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
