We had a ZFS panic last night on a machine that hosts all my mail and = web; it was rebooted and it now panics mounting the ZFS root filesystem. The call stack info is: solaris assert: ss =3D=3D NULL, file: = /usr/src/sys/modules/zfs/../../cddl/contrib/opensource/uts/common/fs/zfs/s= pace_map.c, line: 109 kdb_backtrace panic space_map_add space_map_load metaslab_activate metaslab_allocate zio_dva_allocate=09 zio_execute taskqueue_run_locked taskqueue_thread_loop fork_exit fork_trampoline I can boot from the live DVD filesystem, but I can only mount the pool = read-only without getting the same kernel panic. This is with FreeBSD = 9.0. The machine is remote, and I don't have access other than through a DRAC = console port (so I can't cut and paste; sorry for the poor stack trace). Is anyone here in the position to advice me how I might process to get = this machine mounting and running again in multi-user mode? Thanks so much. Joe p.s. the config, btw, is a ZFS mirror on two ad devices. It's got a ZFS = root file system.=
