Comment 2 Vasishta 2022-03-18 15:37:05 UTC
1) information on --rbd-default-clone-format is that if user has not set set-require-min-compat-client to greater than or equal to mimic, user can use `--rbd-default-clone-format 2` with rbd clone command to create clone of version 2
but using --rbd-default-clone-format per image basis is not recommended - Ref - https://bugzilla.redhat.com/show_bug.cgi?id=2065592#c1

2) in protecting snapshot section, we need to mention that snapshot need not to be protected to be able to create clone as clone v2 is doesn't need snapshot to be protected.

3) We need to mention that is set-require-min-compat-client is greater than or equal to mimic, by default clone v2 would be created.
but clients older than mimic won't be able to access those RBD images.
