I have 3 ZFS datasets that I can not destroy. ZFS Master shows them as being "greyed-out" and when I try to destroy them, I get this error:

"Destroy Result

  cachemirror/zfs backups/cache_domains/haos_ova-11.1.qcow2: Operation not permitted".

 

If I go into the cli, this directory no longer is viewable, but if I try to re-create it, I am told that it already exists. But if I try to rmdir it, I am told "No such file or directory". It appears that I am in a catch-22 here. There has to be a way to remove this, but I cannot figure it out. There are no snapshots of these datasets either, so I am not sure what thinks they still exist?

Post the output of

zfs list -t all

 

Its was rather large, so I dumped it to a text file.

output.txt

Now post the output of:

 

zfs get all cachemirror/zfs backups/cache_domains/haos_ova-11.1.qcow2

 

# zfs get all cachemirror/zfs backups/cache_domains/haos_ova-11.1.qcow2
cannot open 'cachemirror/zfs': dataset does not exist
cannot open 'backups/cache_domains/haos_ova-11.1.qcow2': dataset does not exist

Not sure what it could be, the dataset appears on the list, so it should exist, did you try an array restart? Or just umnount the fs and remount.

I am going to try a complete reboot this weekend. I will let you you know the results.

 

Thanks for the help!

This is really odd... I got a window to reboot my UnRAID box and was able to delete all 3 of the ZFS datasets that were giving me issues.
