Hi, I recently upgraded my RHCS cluster from v4 to v5 and moved to containerized daemons (podman) along the way. I noticed that there are a huge number of logs going to journald on each of my hosts. I am unsure why there are so many. I tried changing the logging level at runtime with commands like these (from the ceph docs): ceph tell osd.\* config set debug_osd 0/5 I tried adjusting several different subsystems (also with 0/0) but I noticed that logs seem to come at the same rate/content. I'm not sure what to try next? Is there a way to trace where logs are coming from? Some of the sample log entries are events like this on the OSD nodes: Jun 04 10:34:02 pf-osd1 ceph-osd-0[182875]: 2024-06-04T10:34:02.470-0600 7fc049c03700 -1 osd.0 pg_epoch: 703151 pg[35.39s0( v 703141'789389 (701266'780746,703141'789389] local-lis/les=702935/702936 n=48162 ec=63726/27988 lis/c=702935/702935 les/c/f=702936/702936/0 sis=702935) [0,194,132,3,177,159,83,18,149,14,145]p0(0) r=0 lpr=702935 crt=703141'789389 lcod 703141'789388 mlcod 703141'789388 active+clean planned DEEP_SCRUB_ON_ERROR] scrubber <NotActive/>: handle_scrub_reserve_grant: received unsolicited reservation grant from osd 177(4) (0x55fdea6c4000) These are very verbose messages and occur roughly every 0.5 second per daemon. On a cluster with 200 daemons this is getting unmanageable and is flooding my syslog servers. Any advice on how to tame all the logs would be greatly appreciated!
