That's sad

thanks sommerfeld, such a silly move I did, erasing days of work ;)

snapshots do not disappear by itself, something/someon must remove them. you can check zpool history

tsoome: beadm rollback destroys any newer snapshots; see block comment above be_rollback() in usr/src/lib/libbe/common/be_snapshot.c

ah, my bad, missed 'rollback'

probably because I neved use rollback myself:D

would be safer if it required an additional flag to delete newer snapshots but then it gets messy when there are multiple filesystems involved (and it could be racing with something that'

that's creating snapshots...)

the way the snapshot ownership (if you will) moves around in there has never not confused me

(that is in `beadm list -s`)
