How to keep "outside" snapshots from mounting as shares

[Flox]

Hi again, @orangejulio ,

First of all: thanks a lot for all your experimentation and your very constructive and helpful feedback. That’s excellent to see and very valuable to the community.

@orangejulio

I recognize that this is an unorthodox way to use Rockstor, as I’m stepping outside of it a bit. I’d like to be able to maintain my own automated backups until such a point that I set up a 2nd Rockstor server.

I’m not sure about others but I personally don’t see that as that unorthodox. I personally would love to have Rockstor better support such “custom”/third party backups options in the future and have always been curious about them.

@orangejulio

Is there a way that I can put them somewhere or name them in such a way that Rockstor will ignore them? I’ve done a lot of searching, but I can’t find an answer to this.

Btrfs-related operations are @phillxnet’s expertise but I know they’re currently very busy with our next RPM release (Release 4.6.1-0 · rockstor/rockstor-core · GitHub) so, in the meantime, I would like to point you towards the following thread that seems similar to me (pardon my misunderstanding otherwise):
Bees .beeshome subvolume getting remounted by Rockstor

As you can see, this led to the implementation of a system-wide “ignore” list for subvolumes and it seems this could fix your use case as well: Add system-wide subvol exclusion mechanism (#2223) by phillxnet · Pull Request #2270 · rockstor/rockstor-core · GitHub. It may very well depend on the path of your subvolume(s) to be ignored, but it seems to be promising at the very least.
