Hi, I have a doubt. In user serviceable snapshots as of now statfs call is not implemented. There are 2 ways how statfs can be handled. 1) Whenever snapview-client xlator gets statfs call on a path that belongs to snapshot world, it can send the statfs call to the main volume itself, with the path and the inode being set to the root of the main volume. OR 2) It can redirect the call to the snapshot world (the snapshot demon which talks to all the snapshots of that particular volume) and send back the reply that it has obtained.
Each entry in .snaps can be thought of as a specially mounted read-only filesystem and doing a statfs in such a filesystem should generate statistics associated with that. So approach 2. seems more appropriate.
