How interesting; it looks like that command was added post-dumpling and not backported. It's probably suitable for backport; I've also created a ticket to create docs for this (http://tracker.ceph.com/issues/6731). Did you create this cluster on an older development release? That should be the only way for the option to have been enabled without you setting it explicitly. (I'm just following what the release notes at http://ceph.com/docs/master/release-notes say about hashpspool). -Greg On Tue, Nov 5, 2013 at 1:32 AM, Fuchs, Andreas (SwissTXT) <Andreas.Fuchs@xxxxxxxxxxx> wrote: > The command you recomend doesnt work, also I cannot find something in the command reference how to do it. > > How can the settings be verified? > Ceph osd dump does not show any flags: > pool 2 'rbd' rep size 2 min_size 1 crush_ruleset 2 object_hash rjenkins pg_num 64 pgp_num 64 last_change 1 owner 0 > > also I cannot find something in the current running crushmap: > rule rbd { > ruleset 2 > type replicated > min_size 1 > max_size 10 > step take default > step chooseleaf firstn 0 type host > step emit > } > > I'm I really looking in the right direction? > > > >> -----Original Message----- >> From: Gregory Farnum [mailto:greg@xxxxxxxxxxx] >> Sent: Montag, 4.
