I upgraded our two main backup servers which are doing I/O via rsync/rsnapshot and sending ZFS snapshots to the other remote site every 15 minutes. I had several instances where the machines went unresponsive. They didn't panic, and they did respond to CTRL+ALT+DEL on the console, but they lost all networking and wouldn't do anything else. The only change was I enabled zfs prefetch which I previously had disabled for performance reasons. It never caused this issue on 9.1 when I had it enabled, though. The fix definitely was turning off prefetch again which doesn't bother me too much, but I can't use this environment to try to help debug it as it's important production data. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
