lxc.mount.entry vs mp0

[j7b]

What's the difference between these two configs? I've read the documentation but it's not clear in my head and they don't mention the former.

lxc.mount.entry: /dpool/data data none bind 0 0

mp0: /dpool/data,mp=/data

Our suspicion is that the later is a FUSE mount where-as the former could be a more direct mount. Just looking for clarification as I'm having some performance issues with the later that I want to diagnose.

both are bind mounts, the difference is that in the latter case PVE is aware of it, and in the former it's not.

Thank you for the clarification, Fabian!

Great answer.

I assume that matters for things like snapshots and backups?

 

[fabian]

yes, exactly. bind mounts that PVE knows about will be handled in some fashion (depending on what you are doing, that might mean blocking certain actions, ignoring them, doing something with them), those that only LXC knows about not.
