zfs discuss - Mar 2007 - ZFS filesystem disappeared after reboot?

Using Solaris 10, Update 2....

I''ve just rebooted my desktop and I have discovered that a ZFS
filesystem appears to have gone missing.

The filesystem in question was called "biscuit/home" and should
have been modified to have its mountpoint set to /export/home.

Before the reboot, I did a lot of trimming, to kill off old ZFS
filesystems (workspace snapshots, clones, etc) that I was no
longer using...(-R was used)

I''m pretty confident that I never deleted this one as my mail reader
keeps all of its local files there and it was working fine until I just
rebooted and it would have let me know that things were amiss,
given that restarting it before the reboot had it working and trying
to start it now doesn''t.

Is there any way I can try to discover if it was my fingers before
the reboot or if ZFS gobbled it up by mistake?

Shell history files don''t appear to be of use.

In newer bits there''s zpool history which could have been useful.

Are you sure file system is gone or maybe it''s just not mounted?

"zfs list" should show it.  Try "zfs mount -a" and check to
see if it
gets mounted or gives you an error, since zfs won''t mount over things
like automounted filesystems or existing directories.

Actually, the wrap up is much more embaressing than this...

The filesystem in question wasn''t in ZFS, it was/is still in UFS,
and I''ve had "no" in the "mount at boot" column in
/etc/vfstab.
Most likely so that I won''t have any problems umount''ing it
when
i next reboot''d so I could turn it into a ZFS filesystem :*)

Next thing to do is move it *to* ZFS so I don''t have this problem
again :-)
