That will shed a bit more light on what happened (and the simplest way to fix it). sage > Any way to make this work again?

You added a populated pool complete with snapshots on top of a base tier without snapshots. Apparently, it caused an existential crisis for the snapshot code. That's one of the reasons why there is a --force-nonempty flag for that operation, I think. I think the immediate answer is probably to disallow pools with snapshots as a cache tier altogether until we think of a good way to make it work. > -Sam > > ----- Original Message ----- > From: "tuomas juntunen" <tuomas.juntunen@xxxxxxxxxxxxxxx> > To: "Samuel Just" <sjust@xxxxxxxxxx> > Cc: ceph-users@xxxxxxxxxxxxxx > Sent: Monday, April 27, 2015 4:56:58 AM > Subject: Re: Upgrade from Giant to Hammer and after some basic operations most of the OSD's went down > > > > The following: > > ceph osd tier add img images --force-nonempty ceph osd tier cache-mode images forward ceph osd tier set-overlay img images > > Idea was to make images as a tier to img, move data to img then change clients to use the new img pool. > > Br, > Tuomas > > > Can you explain exactly what you mean by: > > > > "Also I created one pool for tier to be able to move data without outage." > > > > -Sam > > ----- Original Message ----- > > From: "tuomas juntunen" <tuomas.juntunen@xxxxxxxxxxxxxxx> > > To: "Ian Colle" <icolle@xxxxxxxxxx> > > Cc: ceph-users@xxxxxxxxxxxxxx > > Sent: Monday, April 27, 2015 4:23:44 AM > > Subject: Re: Upgrade from Giant to Hammer and after some > > basic operations most of the OSD's went down > > > > Hi > > > > Any solution for this yet? > > > > Br, > > Tuomas > > > >> It looks like you may have hit http://tracker.ceph.com/issues/7915 > >> > >> Ian R.
