So I rebuilt my production mail server as Solaris 10 06/06 with zfs, it ran
for three months, and it's had no hardware errors. But my zfs file system
seems to have died a quiet death. Sun engineering response was to point to
the FMRI, which says to throw out the zfs partition and start over. I'm real
reluctant to do that, since it'll take hours to do a tape restore, and we
don't know what's wrong. I'm seriously wondering if I should just toss zfs.
Again, this is Solaris 10 06/06, not some beta version. It's an older
server, a 280R with an older SCSI RaidKing
The sun engineer is escalating but thanks for any clues or thoughts. I don't
want to erase the evidence until we get some idea what's wrong.
