On a rebuild of a new server, I added a new SSD to one of my Cache pools (Board) and then relocated my Domains to that new cache pool. That worked well, and the VMs work fine from the new pool location..

 

However, this process left behind a Domains folder on the old SSD (cache-nvme) which contains just 2 subfolders, Windows and Ubuntu, but nothing else, just the 2 empty folders.

 

Try as I might, I can't delete these folders - the subfolders are empty, but I've tried all ways to get rid of them, but they simply won't go. 

 

It's no big deal, but Fix Common Problems routinely reports "Share domains set to use pool board, but files / folders exist on the cache_nvme pool". I can ignore this message - but I don't like running with constant configuration errors.

 

Can anybody suggest a fix for this?

 

Thanks

Have you used mc from the console?

Yes, first place I tried, but even the Commander couldn't delete them. It tells me the resource is busy. I've switched off VMs in Settings, so I don't know what is using it.

 

Does a file system check come back clean?

Sorry, how do I do a File System Check?

 

It's formatted as ZFS, and I couldn't find details of checking a ZFS system in Docs.

 

OK, we've moved on a bit. I realised, once I told you it was formatted ZFS, that it was ZFS which was protecting it. So I went to the ZFS Master tab and was able to delete the two "child" directories in the Domains folder. However, I still can't delete the Domains folder as ZFS won't allow that.

I'm not well versed in ZFS, but I think you have to destroy the dataset.
