Description

(1)I create a rbd block named abc;
rbd create abc --size 10

(2)then I create a snapshoot of abc;
rbd snap create --image abc --snap s1
rbd snap create --image abc --snap s2

(3)then I export abc in a local file;
rbd export abc local_file

(4)import local_file as a new rbd block;
rbd import local_file new_rbd;

(5)but the snapshoots(s1, s2) are disappear!
rbd snap ls new_rbd

Is this a bug or someting else?

but could I add a feature about "--with-snap", so it can preserve snapshots?

export-diff / import-diff do preserve snapshots -- I think this is the tool you want to use.
