Here is the result of ceph osd tree As showed at the last ceph day in Paris, we have multiple root but the ruleset 52 entered the crushmap on root default. # id weight type name up/down reweight -100 0.09998 root diskroot -110 0.04999 diskclass fastsata 0 0.009995 osd.0 up 1 1 0.009995 osd.1 up 1 2 0.009995 osd.2 up 1 3 0.009995 osd.3 up 1 -120 0.04999 diskclass slowsata 4 0.009995 osd.4 up 1 5 0.009995 osd.5 up 1 6 0.009995 osd.6 up 1 7 0.009995 osd.7 up 1 8 0.009995 osd.8 up 1 9 0.009995 osd.9 up 1 -5 0.2 root approot -50 0.09999 appclient apprgw -501 0.04999 appclass fastrgw 0 0.009995 osd.0 up 1 1 0.009995 osd.1 up 1 2 0.009995 osd.2 up 1 3 0.009995 osd.3 up 1 -502 0.04999 appclass slowrgw 4 0.009995 osd.4 up 1 5 0.009995 osd.5 up 1 6 0.009995 osd.6 up 1 7 0.009995 osd.7 up 1 8 0.009995 osd.8 up 1 9 0.009995 osd.9 up 1 -51 0.09999 appclient appstd -511 0.04999 appclass faststd 0 0.009995 osd.0 up 1 1 0.009995 osd.1 up 1 2 0.009995 osd.2 up 1 3 0.009995 osd.3 up 1 -512 0.04999 appclass slowstd 4 0.009995 osd.4 up 1 5 0.009995 osd.5 up 1 6 0.009995 osd.6 up 1 7 0.009995 osd.7 up 1 8 0.009995 osd.8 up 1 9 0.009995 osd.9 up 1 -1 0.09999 root default -2 0.09999 datacenter nanterre -3 0.09999 platform sandbox -13 0.01999 host p-sbceph13 0 0.009995 osd.0 up 1 5 0.009995 osd.5 up 1 -14 0.01999 host p-sbceph14 1 0.009995 osd.1 up 1 6 0.009995 osd.6 up 1 -15 0.01999 host p-sbceph15 2 0.009995 osd.2 up 1 7 0.009995 osd.7 up 1 -12 0.01999 host p-sbceph12 3 0.009995 osd.3 up 1 8 0.009995 osd.8 up 1 -11 0.01999 host p-sbceph11 4 0.009995 osd.4 up 1 9 0.009995 osd.9 up 1 Best regards -----Message d'origine----- De : Loic Dachary [mailto:loic@xxxxxxxxxxx] Envoyé : mardi 14 octobre 2014 12:12 À : CHEVALIER Ghislain IMT/OLPS; ceph-devel@xxxxxxxxxxxxxxx Objet : Re: [Ceph-Devel] NO pg created for eruasre-coded pool On 14/10/2014 02:07, ghislain.chevalier@xxxxxxxxxx wrote: > Hi all, > > Context : > Ceph : Firefly 0.80.6 > Sandbox Platform : Ubuntu 12.04 LTS, 5 VM (VMware), 3 mons, 10 osd > > > Issue: > I created an erasure-coded pool using the default profile > --> ceph osd pool create ecpool 128 128 erasure default > the erasure-code rule was dynamically created and associated to the pool. > root@p-sbceph14:/etc/ceph# ceph osd crush rule dump erasure-code { > "rule_id": 7, > "rule_name": "erasure-code", > "ruleset": 52, > "type": 3, > "min_size": 3, > "max_size": 20, > "steps": [ > { "op": "set_chooseleaf_tries", > "num": 5}, > { "op": "take", > "item": -1, > "item_name": "default"}, > { "op": "chooseleaf_indep", > "num": 0, > "type": "host"}, > { "op": "emit"}]} > root@p-sbceph14:/var/log/ceph# ceph osd pool get ecpool crush_ruleset > crush_ruleset: 52 > No error message was displayed at pool creation but no pgs were created. > --> rados lspools confirms the pool is created but rados/ceph df shows > --> no pg for this pool > > The command "rados -p ecpool put services /etc/services" is inactive > (stalled) and the following message is encountered in ceph.log > 2014-10-14 10:36:50.189432 osd.5 10.192.134.123:6804/21505 799 : [WRN] > slow request 960.230073 seconds old, received at 2014-10-14 > 10:20:49.959255: osd_op(client.1192643.0:1 services [writefull > 0~19281] 100.5a48a9c2 ondisk+write e11869) v4 currently waiting for pg > to exist locally > > I don't know if I missed something or if the problem is somewhere else..
