Shoot… ;) Right after hitting the send button, I issued this:

After destroying this "invisible" Dataset 
vmpool/iSCSI-Targets/EyeTV/iSCSI-Targets dataset, I was able to delete it's 
parent datasets. 

Sorry for the noise.

[OmniOS-discuss] Can't destroy ZFS

2017-09-22 Thread Stephan Budach 
Hi, 


after having received a zvol from my old S11 box vis zfs send/recv and being 
unable to re-import the LUN via stmfadm, I decided to remove that zvol/ZFS and 
start over. However, I cannot remove that particular ZFS and trying to do so 
yields this strange error: 


root@omnios:~# zfs destroy vmpool/iSCSI-Targets/EyeTV 
cannot destroy 'vmpool/iSCSI-Targets/EyeTV': dataset already exists 


The zpool currently looks like this… (by the way, no snaps whatsoever on it): 


root@omnios:~# zfs list -r vmpool 
NAME USED AVAIL REFER MOUNTPOINT 
vmpool 348G 3.17T 23K /vmpool 
vmpool/esxi 39.4G 1.96T 39.4G /vmpool/esxi 
vmpool/iSCSI-Targets 238G 3.17T 23K /tank/iSCSI-Targets 
vmpool/iSCSI-Targets/EyeTV 238G 3.17T 238G - 
vmpool/nfsCloudData 70.3G 186G 70.3G /vmpool/nfsCloudData 
vmpool/nfsZimbraData 41K 100G 41K /vmpool/nfsZimbraData 




I have scrubbed the web a bit for this particular error, but all the reports 
seem to relate to either snapshots or clones. 


Any idea is greatly appeciated. 


Cheers, 
stephan
