Steps to reproduce:
Assume your volume is on /mnt/VOL1
Side note: because the data came from another volume that was snapshotted restoring it from the snapshot was a breeze. Hurray ZFS.
(tested in 8.2.0 and 8.3.0RC2)
Assume your volume is on /mnt/VOL1
- On this volume create a new directory /mnt/VOL1/TEST1 (can be done in the Shell or in my case through a Samba share)
- Create/copy files in that folder
- Create a new dataset with name TEST1 (I remembered/decided I wanted it to be a dataset)
- Result: all existing data in /mnt/VOL1/TEST1 is erased
Side note: because the data came from another volume that was snapshotted restoring it from the snapshot was a breeze. Hurray ZFS.
