Hi again, turns out the long bootstrap time was my own fault. I had some down&out OSDs for quite a long time, which prohibited the monitor from pruning the OSD maps. Makes sense, when I think about it, but I didn't before. Rich's hint to get the cluster to health OK first pointed me in the right direction, as well as the docs on full OSDmap version pruning [1] that mention constraints in OSDMonitor::get_trim_to(). So I destroyed the OSDs (they don't hold any data anyway) and the mon's DBs shrank by almost 8 GB to only ~160 MB. Thanks for helping figuring this out! I promise to not have lingering down&out OSDs anymore. ;-) Best regards, Jan-Philipp [1]: https://docs.ceph.com/en/latest/dev/mon-osdmap-prune/ _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
