Hi, For some reason daily I receive a slow ops which affect the rgw.log pool the most (which is pretty small, 32pg / 57k objects / 9.5GB data)
Could be the issue related to rocksdb tasks? Some log lines: ... 2024-06-18T14:17:43.849+0700 7fd8002ea700 1 heartbeat_map reset_timeout 'OSD::osd_op_tp thread 0x7fd8002ea700' had timed out after 15 2024-06-18T14:17:50.865+0700 7fd81a31e700 -1 osd.461 472771 get_health_metrics reporting 1 slow ops, oldest is osd_op(client.3349483990.0:462716190 22.11 22:8deed178:::meta.log.08e85e9f-c16e-43f0-b88d-362f3b7ced2d.15:head [call log.list in=69b] snapc 0=[] ondisk+read+known_if_redirected e472771) 2024-06-18T14:17:50.865+0700 7fd81a31e700 0 log_channel(cluster) log [WRN] : 1 slow requests (by type [ 'delayed' : 1 ] most affected pool [ 'dc.rgw.log' : 1 ]) 2024-06-18T14:19:36.040+0700 7fd81e5b4700 1 heartbeat_map is_healthy 'OSD::osd_op_tp ... 2024-06-18T14:19:51.908+0700 7fd81a31e700 -1 osd.461 472771 get_health_metrics reporting 2 slow ops, oldest is osd_op(client.3371539359.0:5095510 22.11 22:8df1b9e1:::datalog.sync-status.shard.61c9d940-fde4-4bed-9389-edc8d7741817.111: head [call lock.lock in=64b] snapc 0=[] ondisk+write+known_if_redirected e472771) 2024-06-18T14:19:51.908+0700 7fd81a31e700 0 log_channel(cluster) log [WRN] : 2 slow requests (by type [ 'delayed' : 2 ] most affected pool [ 'dc.rgw.log' : 2 ]) 2024-06-18T14:19:52.899+0700 7fd81a31e700 -1 osd.461 472771 get_health_metrics reporting 2 slow ops, oldest is osd_op(client.3371539359.0:5095510 22.11 22:8df1b9e1:::datalog.sync-status.shard.61c9d940-fde4-4bed-9389-edc8d7741817.111: I found this thread: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/FR5V466HBXGRVL3Z3RAFKUPQ2FGK2T53/ but I think it is not relevant for me. We use only SSDs without separated rocksdb so we don' have spillover. CPU is not overloaded (80% idle) however it's interesting that in vmstat the "r" is pretty big which indicates waiting list for cpu: procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 12 0 0 6205288 329803136 15633844 0 0 2149 1894 0 0 5 3 92 0 0 17 0 0 6156780 329827840 15637252 0 0 125584 250416 646098 1965051 10 8 82 0 0 21 0 0 6154636 329849504 15636112 0 0 99320 245024 493324 1682377 7 6 87 0 0 16 0 0 6144256 329869664 15636924 0 0 87484 301968 623345 1993374 8 7 84 0 0 19 0 0 6057012 329890080 15637932 0 0 160444 303664 549194 1820562 8 6 85 0 0 Any idea what this could indicate on octopus 15.2.17 with ubuntu 20.04? ty ________________________________ This message is confidential and is for the sole use of the intended recipient(s).
