SOLVED Accidentally promoted dataset and now I can't delete it

[ninjai]

I created a dataset to fire up nextcloud in and noticed I made a typo in the name. So instead of clicking on "Destroy", I accidentally clicked on the "promote dataset" button, which gave me no prompt at all and just promoted it.

I'm not sure what this means, but now I can't delete it:

Code:

cannot destroy 'Storage/Jails/nextloud': filesystem has dependent clones use '-R' to destroy the following datasets: Storage/Jails/.warden-template-standard@auto-20180323.1800-2w Storage/Jails/.warden-template-standard@auto-20180323.1200-2w Storage/Jails/.warden-template-standard

Code:

@freenas ~]$ zfs get origin | grep nextloud
Storage/Jails/.warden-template-standard											  origin	Storage/Jails/nextloud@clean													-
Storage/Jails/nextloud															   origin	-																			   -
Storage/Jails/nextloud@clean														 origin	-

Code:

@freenas /mnt/Storage/Jails]$ zfs list -t snapshot | grep nextloud
Storage/Jails/nextloud@clean															 0	  -  2.91G  -

I'm not sure how to proceed. I don't want to ruin any of the other data on my NAS. The dataset is in the same spot as all my other jail datasets (/mnt/Storage/Jails/). What has this "promote dataset" thing actually done and now do I get rid of this dataset without losing anything else?

Can you please provide a screenshot of your dataset structure from the FreeNAS GUI?

"Promote" data set? What the heck is that? Is this some newfanglery in FreeNAS 11?

Allan has explained this to me. This is something to do with cloned datasets.

Promote the original dataset and the situation will be reversed.

Right, in this case:

Code:

cannot destroy 'Storage/Jails/nextloud':
  filesystem has dependent clones use '-R' to destroy the following datasets:
	Storage/Jails/.warden-template-standard@auto-20180323.1800-2w
	Storage/Jails/.warden-template-standard@auto-20180323.1200-2w
	Storage/Jails/.warden-template-standard

You want to promote the warden template:

Code:

zfs promote Storage/Jails/.warden-template-standard

You should then be able to destroy the nextloud dataset and snapshots:

Code:

zfs destroy -r Storage/Jails/nextloud

'-r' destroys dependent snapshots
'-R' destroys dependent snapshots and datasets
You likely don't want to use '-R'

Great, thank you Jailer and fracai! This resolved my issue.
