Sometime on sunday our main server paniced with the following error: panic: solaris assert: sm->sm_space == space (0x5e45000 == 0x5e45600), file: /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/space_map.c, line: 361 I did some goolging and found a couple of refereces to other people who have seen this. Both of them, however, could not recover the pool and needed to restore all the data from backups (which I am in the process of). Soes anyone know anything more about this ? Specificly if it a known rpoblem which is fixed in 8.0 ? I couldn't find a PR of any kind, but the fact that a machine can spontaneously loose all it's data from a set of filesystems worries me greatly. cheers, -pete.
