Just a small note, the memory target settings are more or less only for how the OSD should behave while in normal operation, so it will control the amount of cache memory used and so on. If the OSD decides it needs 50GB ram to do some recovery/GC/whatever-it-does at startup, this will be on top of whatever memory target you have set, not within. There are lots and lots of different places where OSDs can and will allocate memory and any ceph.conf OSD setting will only affect a few of those, mostly concerning how much ram it should try to use in the default, easy cases. When doing recoveries or compactions or any other operation that isn't just related to serving data to ceph clients, it will allocate whatever it thinks is needed. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
