Thanks, Eugen. I’m afraid I haven’t yet found a way to either disable the CephPGImbalance alert or change it to handle different OSD sizes. Changing /var/lib/ceph/<cluster_id>/home/ceph_default_alerts.yml doesn’t seem to have any effect, and I haven’t even managed to change the behavior from within the running prometheus container. If you have a functioning workaround, can you give a little more detail on exactly what yaml file you’re changing and where?

We are using cephadm to manage a 19.2.0 cluster on fully-updated AlmaLinux 9 hosts, and would greatly appreciate help modifying or overriding the alert rules in ceph_default_alerts.yml.

Although I don’t believe it causes any technical issues with our configuration, our dashboard is full of CephPGImbalance alerts that would be nice to clean up without having to create periodic silences. >> >> Any help or suggestions would be greatly appreciated. >> >> Many thanks, >> Devin >> >> [1] https://github.com/rook/rook/discussions/13126#discussioncomment-10043490 >> _______________________________________________ >> ceph-users mailing list -- ceph-users@xxxxxxx >> To unsubscribe send an email to ceph-users-leave@xxxxxxx > > > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
