Thanks for the help but how do I track down this issue? If data is inaccessible, that's a very bad thing given this is production. # ceph osd dump | grep pool pool 13 '.rgw.buckets' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 4800 pgp_num 4800 last_change 1198 owner 0 pool 14 '.rgw' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 242 owner 18446744073709551615 pool 15 '.rgw.gc' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 243 owner 18446744073709551615 pool 16 '.rgw.control' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 244 owner 18446744073709551615 pool 17 '.users.uid' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 246 owner 0 pool 18 '.users.email' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 248 owner 0 pool 19 '.users' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 250 owner 0 pool 20 '.usage' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 256 owner 18446744073709551615 pool 21 '.users.swift' rep size 2 crush_ruleset 0 object_hash rjenkins pg_num 8 pgp_num 8 last_change 1138 owner 0 Nelson Jeppesen Disney Technology Solutions and Services Phone 206-588-5001 -----Original Message----- From: Gregory Farnum [mailto:greg@xxxxxxxxxxx] Sent: Monday, April 15, 2013 9:34 AM To: Jeppesen, Nelson Cc: ceph-users@xxxxxxxxxxxxxx Subject: Re: ceph -w question "Incomplete" means that there are fewer than the minimum copies of the placement group (by default, half of the requested size, rounded up). In general rebooting one node shouldn't do that unless you've changed your minimum size on the pool, and it does mean that data in those PGs is unaccessible. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com On Mon, Apr 15, 2013 at 9:01 AM, Jeppesen, Nelson <Nelson.Jeppesen@xxxxxxxxxx> wrote: > When I reboot any node in my prod environment with no activity I see > incomplete pgs.
