The first and hopefully easy one: I have a situation where I have two pools that are rarely used (the third will be in use after I can get through these issues), but they need to present at the whims of our cloud team. Is there a way I can turn off ‘2 pools have many more objects per pg than average’?
What I have done to this point is played with ‘mon_pg_warn_max_object_skew’, but that didn’t remove the message. After googling and looking through the docs, nothing stood out to me to resolve the issue. Technical info: [[email protected] ~] # ceph health detail HEALTH_WARN 2 pools have many more objects per pg than average MANY_OBJECTS_PER_PG 2 pools have many more objects per pg than average pool images objects per pg (480) is more than 60 times cluster average (8) pool metrics objects per pg (336) is more than 42 times cluster average (8) The second: I’m seeing osds randomly getting marked as down, but then state they are still running. This issue wasn’t present before the upgrade. This is a multipath setup but the paths appear healthy and the cluster isn’t really being utilized at the moment. Please let me know if you want more information: Ceph.log: 2018-01-25 14:56:29.011831 mon.mon01 mon.0 10.20.57.10:6789/0 823 : cluster [INF] osd.12 marked down after no beacon for 300.775605 seconds 2018-01-25 14:56:29.013280 mon.mon01 mon.0 10.20.57.10:6789/0 824 : cluster [WRN] Health check failed: 1 osds down (OSD_DOWN) 2018-01-25 14:56:32.034002 mon.mon01 mon.0 10.20.57.10:6789/0 830 : cluster [INF] Health check cleared: OSD_DOWN (was: 1 osds down) 2018-01-25 14:56:31.322228 osd.12 osd.12 10.20.57.14:6804/4163 1 : cluster [WRN] Monitor daemon marked osd.12 down, but it is still running Ceph-osd.12.log: 2018-01-25 14:56:00.606493 7facfde03700 4 rocksdb: (Original Log Time 2018/01/25-14:56:00.602100) [/home/jenkins-build/build/workspace/ceph-build/ARCH/x86_64/AVAILABLE_ARCH/x86_64/AVAILABLE_DIST/centos7/DIST/centos7/MACHINE_SIZE/huge/release/12.2.2/rpm/el7/BUILD/ceph-12.2.2/src/rocksdb/db/memtable_list.cc:360] [default] Level-0 commit table #213 started 2018-01-25 14:56:00.606498 7facfde03700 4 rocksdb: (Original Log Time 2018/01/25-14:56:00.606406) [/home/jenkins-build/build/workspace/ceph-build/ARCH/x86_64/AVAILABLE_ARCH/x86_64/AVAILABLE_DIST/centos7/DIST/centos7/MACHINE_SIZE/huge/release/12.2.2/rpm/el7/BUILD/ceph-12.2.2/src/rocksdb/db/memtable_list.cc:383] [default] Level-0 commit table #213: memtable #1 done 2018-01-25 14:56:00.606517 7facfde03700 4 rocksdb: (Original Log Time 2018/01/25-14:56:00.606437) EVENT_LOG_v1 {"time_micros": 1516917360606429, "job": 29, "event": "flush_finished", "lsm_state": [2, 1, 1, 0, 0, 0, 0], "immutable_memtables": 0} 2018-01-25 14:56:00.606529 7facfde03700 4 rocksdb: (Original Log Time 2018/01/25-14:56:00.606466) [/home/jenkins-build/build/workspace/ceph-build/ARCH/x86_64/AVAILABLE_ARCH/x86_64/AVAILABLE_DIST/centos7/DIST/centos7/MACHINE_SIZE/huge/release/12.2.2/rpm/el7/BUILD/ceph-12.2.2/src/rocksdb/db/db_impl_compaction_flush.cc:132] [default] Level summary: base level 1 max bytes base 268435456 files[2 1 1 0 0 0 0] max score 0.50 2018-01-25 14:56:00.606538 7facfde03700 4 rocksdb: [/home/jenkins-build/build/workspace/ceph-build/ARCH/x86_64/AVAILABLE_ARCH/x86_64/AVAILABLE_DIST/centos7/DIST/centos7/MACHINE_SIZE/huge/release/12.2.2/rpm/el7/BUILD/ceph-12.2.2/src/rocksdb/db/db_impl_files.cc:388] [JOB 29] Try to delete WAL files size 252104127, prev total WAL file size 253684537, number of live WAL files 2. 2018-01-25 14:56:31.322223 7fad1262c700 0 log_channel(cluster) log [WRN] : Monitor daemon marked osd.12 down, but it is still running 2018-01-25 14:56:31.322233 7fad1262c700 0 log_channel(cluster) log [DBG] : map e18531 wrongly marked me down at e18530 2018-01-25 14:56:31.322236 7fad1262c700 1 osd.12 18531 start_waiting_for_healthy 2018-01-25 14:56:31.327816 7fad0c620700 1 osd.12 pg_epoch: 18530 pg[14.8f( v 18432'17 (0'0,18432'17] local-lis/les=18521/18522 n=1 ec=18405/18405 lis/c 18521/18521 les/c/f 18522/18522/0 18530/18530/18530) [3,19] r=-1 lpr=18530 pi=[18521,18530)/1 luod=0'0 crt=18432'17 lcod 0'0 active] start_peering_interval up [12,3,19] -> [3,19], acting [12,3,19] -> [3,19], acting_primary 12 -> 3, up_primary 12 -> 3, role 0 -> -1, features acting 2305244844532236283 upacting 2305244844532236283 2018-01-25 14:56:31.327851 7fad0be1f700 1 osd.12 pg_epoch: 18530 pg[14.9e( empty local-lis/les=18522/18523 n=0 ec=18405/18405 lis/c 18522/18522 les/c/f 18523/18523/0 18530/18530/18530) [15,10] r=-1 lpr=18530 pi=[18522,18530)/1 crt=0'0 active] start_peering_interval up [12,15,10] -> [15,10], acting [12,15,10] -> [15,10], acting_primary 12 -> 15, up_primary 12 -> 15, role 0 -> -1, features acting 2305244844532236283 upacting 2305244844532236283 2018-01-25 14:56:31.327918 7fad0c620700 1 osd.12 pg_epoch: 18531 pg[14.8f( v 18432'17 (0'0,18432'17] local-lis/les=18521/18522 n=1 ec=18405/18405 lis/c 18521/18521 les/c/f 18522/18522/0 18530/18530/18530) [3,19] r=-1 lpr=18530 pi=[18521,18530)/1 crt=18432'17 lcod 0'0 unknown NOTIFY] state<Start>: transitioning to Stray Ceph osd tree: [[email protected] ceph-conf] #
