Hi, Probably due to too many reboots when the system was livelocked. But now I have the following problem. /sbin/zfs destroy -r zfsraid/backups@Monday cannot destroy 'zfsraid/backups@Monday': dataset does not exist no snapshots destroyed /sbin/zfs snapshot -r zfsraid/backups@Monday cannot create snapshot 'zfsraid/backups@Monday': dataset is busy no snapshots were created /sbin/zfs destroy -r zfsraid/home@$DATE cannot destroy 'zfsraid/home@Monday': dataset does not exist no snapshots destroyed /sbin/zfs snapshot -r zfsraid/home@Monday cannot create snapshot 'zfsraid/home@Monday': dataset is busy no snapshots were created Where this used to work(tm).... I can iterate over all filesystems and then destroy/create a backup. Except for one: # zfs list -r zfsraid/home/trouble NAME USED AVAIL REFER MOUNTPOINT zfsraid/home/trouble 149G 3.49T 148G none zfsraid/home/trouble@Sunday 1.06G - 148G - # zfs destroy -r zfsraid/home/trouble cannot destroy 'zfsraid/home/trouble@Sunday': dataset already exists Exit 1 # zfs destroy zfsraid/home/trouble@Sunday cannot destroy 'zfsraid/home/trouble@Sunday': dataset already exists Exit 1 # zfs destroy -r zfsraid/home/trouble@Sunday cannot destroy 'zfsraid/home/trouble@Sunday': snapshot is cloned no snapshots destroyed But of this last fact I do not remember cloning anything. Nor can I find any suggestions as to the filesystem being cloned..... So how do I get ride of this rouge filesystem. There is something like zdb, but the manual page is purposely vague on how to use that... Thanx, --WjW
