Next message: Igor Brezac: "Re: The Cyrus db (/var/imap/db) is suddenly hundreds of MB!"
Hi everyone,
Due to a problem with a webserver on the same machine, the /var
partition on our mailserver went from over 1GB available to full within
a few minutes.
The Cyrus database lives in /var/imap, and has become corrupt as a
result of this. Initially, we tried to recover from this situation by
stopping all services and moving the offending Apache logfiles away.
But as soon as we made room on /var, Cyrus would use it all up in
/var/imap/db which is now 863MB in size. What's inside:
-rw------- 1 cyrus mail 8192 Oct 6 17:14 __db.001
-rw------- 1 cyrus mail 663552 Oct 6 17:14 __db.002
-rw------- 1 cyrus mail 98304 Oct 6 17:13 __db.003
-rw------- 1 cyrus mail 21061632 Oct 6 17:13 __db.004
-rw------- 1 cyrus mail 32768 Oct 6 17:13 __db.005
-rw------- 1 cyrus mail 10485738 Oct 6 15:58 log.0000000357
-rw------- 1 cyrus mail 10485728 Oct 6 15:58 log.0000000358
-rw------- 1 cyrus mail 10485728 Oct 6 15:58 log.0000000359
(85 of these logfiles in total)
-rw------- 1 cyrus mail 4 Sep 30 18:28 skipstamp
Trying to run 'ctl_cyrusdb -r' takes a few minutes but aborts with a
coredump. When I try to start Cyrus, it tries to recover the database
(but coredumps), then starts copying all these 10MB logfiles into
db.backup and we run out of diskspace again.
Any hints on how to get this system back into working order would be
very much appreciated!
Regards, Paul Boven.
