Re: Can not Mount btrfs No Space left

Hugo,
Thanks, I had not thought of that.
It does mount fine ro so I can access the files.
Any ideas on getting access to delete a few log files or snapshots so
I can mount the volume rw?
If not I will just copy it off onto another, but that will be time consuming.
