So, the base tier is what determines the snapshots for the cache/base pool amalgam. 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.
