By default, when you do something like mount /dev/sdb1 /mnt/btrfs the default subvolume will be mounted under /mnt/btrfs. Snapshots and subvolumes will be visible as subdirectories under it, regardless whether it's in the root or several directories under it. Most likely this is enough for what you need, no need to mess with mounting subvolumes. Mounting subvolumes allows you to see a particular subvolume directly WITHOUT having to see the default subvolume or other subvolumes. This is particularly useful when you use btrfs as "/" or "/home" and want to "rollback" to a previous snapshot. So assuming "snapshots-server-b" above is a snapshot, you can run
I think I start to get it now. Its the fact that subvolumes can be snapshotted etc without mounting them that is the difference. I guess I am too used to thinking like LVM and I was thinking subvolumes where like an LV. They are, but not quite the same.
