looking into how to limit snapshots at the ceph level for RBD snapshots. Ideally ceph would enforce an arbitrary number of snapshots allowable per rbd.
Reading the man page for rbd command I see this option: https://docs.ceph.com/en/quincy/man/8/rbd/#cmdoption-rbd-limit
--limit
Specifies the limit for the number of snapshots permitted.
Seems perfect. But on attempting to use it as such I get an error:
admin@rbdtest:~$ rbd create testpool/test3 --size=100M --limit=3 rbd: unrecognised option '--limit=3'
Where am I going wrong here? Is there another way to enforce a limit of snapshots for RBD? Thanks.
Hi Wes, I think you want "rbd snap limit set --limit 3 testpool/test3". Thanks, Ilya
