thank you for this.Puttingmon_cluster_log_level = infoin[global]section ofceph.conf(and rebooting) now works in PVE 9.1 and ceph squid ( 19.2.3 )
Note:mon_cluster_log_[B]file[/B]_levelis no longer valid and does not work
The pull request mentioned by Tobbe was merged to ceph squid january 2025:

i gave up trying to solve this after reading comments from the devs somewhere that led me to believe that they didn't want to make it possible to turn those messages off.
finally i can get rid of the spam and perhaps see the actual interesting log messages for once.
