This is what i get from a script i run every minute to make the
snapshots larger
if they are not big enough to hold the space.
Further more i take a snapshot every hour, 8 hour, day and week.
(another cronscript does that)
It works with a find /dev/optVG/*snapshot* -exec script {} \;
where script contains a lvdisplay $1 | perlscript
where the perlscript actualy finds out if it is too small and makes it
bigger.
However, at the same time another script run every hour
makes a new snapshot (date +%s)
finds the old, umounts it, mounts the new, and removes the old snapshot
with -f
However, sometimes it doesnt actualy remove it, and leaves the file in
/dev/optVG.
So, now i have 800+ emails (all night) from this cronjob that says the
snapshot doesnt exist.

Yesterday i did an rm -rf on one of the 1hour snapshots that "didnt
exists",
and that seemed to work okay. I'd just like that i dont have to do that

So, i stopped the VG, and the size fits with those files in /dev/optVG/
BUT i still cant see those 1hour snapshots :(
ve:/dev/optVG# lvdisplay /dev/optVG/1hour_snapshot_opt_10352*
lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035237601"
doesn't exist
lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035259201"
doesn't exist
lvdisplay -- logical volume "/dev/optVG/1hour_snapshot_opt_1035266401"
doesn't exist
So, i removed them, and it does appear to be working. How come it
repports them as
non existing, but doesnt remove the "file" in /dev/optVG/
