disappearing snapshots

[Michael Grant]

I've been playing with snapshots (mksnap_ffs) recently.  I've got a
script which does a daily snapshot and keeps 7 days of history.  Last
night, the machine crashed and when it came back up, all the snapshots
referred to the current view of the disk, i.e. I lost the 7-day
history.

I'm running 5.3-release.

Has anyone seen this?  Snapshots should persist beyond reboots,
shouldn't they?

(Yes, I am doing the mdconfig and remounting the snap.)
