Background fsck. Your server crashed, rebooted, started up and fsck is running in the background while everything else continues. Ways to avoid background fsck: * Disable it completely in /etc/rc.conf: background_fsck="NO". Then fsck finishes completely before the OS continues booting, so there may be extended delays if a crash occurs. * Use gjournal so fsck doesn't need to churn over the disks * Turn on softupdates-journaling for a similar effect. The more important thing is to find out why it crashed - if there was a power outage, hardware or software issue. > uname -a: > FreeBSD server.my.local 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 > 07:46:30 UTC 2012 > r...@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 > > > Regards, > Leonardo M.
