You need to either change failure domain to osd or need at least 5 host to satisfy host failure domain. Since it is not satisfying failure domain , pgs are undersized and degraded.. Thanks & Regards Somnath From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of Khang Nguy?n Nh?t Hi, I have 1 cluster as pictured below:
- OSD-host1 run 2 ceph-osd daemon is mounted in /var/ceph/osd0 and /var/ceph/osd1. - OSD-host2 run 2 ceph-osd daemon is mounted in /var/ceph/osd2 and /var/ceph/osd3. - OSD-host3 only run 1 ceph-osd daemon is mounted in the /var/ceph/osd4. - This is my myprofile: jerasure-per-chunk-alignment = false k = 3 m = 2 plugin = jerasure ruleset-failure-domain = host ruleset-root = default technique = reed_sol_van w = 8 When I used it to create a pool CLI: ceph osd create test pool myprofile 8 8 erasure. (id test pool=62) CLI: ceph-s Here are the results /// health HEALTH_WARN 8 pgs degraded 8 pgs stuck unclean 8 pgs undersized monmap e1: 1 mons at {mon0 = x.x.x.x: 6789/0} election epoch 7, quorum 0 mon0 osdmap e441: 5 osds: 5 up, 5 in flags sortbitwise pgmap /// 8 Active + undersized + degraded CLI: health CePH detail HEALTH_WARN 8 pgs degraded; 8 pgs stuck unclean; 8 pgs undersized 62.6 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [1,2,2147483647,2147483647,4] 62.7 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [2,0,2147483647,4,2147483647] 62.4 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [3,0,4,2147483647,2147483647] 62.5 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [0,4,2147483647,3,2147483647] 62.2 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [1,2147483647,2147483647,4,2] 62.3 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [2,2147483647,0,4,2147483647] 62.0 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [0,3,2147483647,4,2147483647] 62.1 pg is stuck unclean since forever, current degraded state active + + undersized, last acting [4,0,3,2147483647,2147483647] is active + 62.1 pg undersized + degraded, acting [4,0,3,2147483647,2147483647] is active + 62.0 pg undersized + degraded, acting [0,3,2147483647,4,2147483647] is active + 62.3 pg undersized + degraded, acting [2,2147483647,0,4,2147483647] is active + 62.2 pg undersized + degraded, acting [1,2147483647,2147483647,4,2] is active + 62.5 pg undersized + degraded, acting [0,4,2147483647,3,2147483647] is active + 62.4 pg undersized + degraded, acting [3,0,4,2147483647,2147483647] is active + 62.7 pg undersized + degraded, acting [2,0,2147483647,4,2147483647] is active + 62.6 pg undersized + degraded, acting [1,2,2147483647,2147483647,4] This is related to reasonable ruleset-failure-domain? Can somebody please help me out ? Thank ! |
