Hello list,
i currently hold 3 snapshots per rbd image for my virtual systems.
What i miss in the current documentation:
* details about the implementation of snapshots
o implementation details
o which scenarios create high overhead per snapshot
o what causes the really short performance degration on snapshot
creation/deletion
o why do i not see a significant rbd performance degration if
there a numerous snapshots
o ....
* details and recommendations about the overhead of snapshots
o what performance penalty do i have to expect for a write/read iop
o what are the edgecases of the implemnetation
o how many snapshots per image (i.e virtual machine) might be a
good idea
o ...
Regards
Marc
