Hi, that sounds like the pg_autoscaler is doing its work. Check with: ceph osd pool autoscale-status I don't think ceph is eating itself or that you're losing data. ;-) Zitat von Dave Hall <kdhall@xxxxxxxxxxxxxx>:
Hello, About 3 weeks ago I added a node and increased the number of OSDs in my cluster from 24 to 32, and then marked one old OSD down because it was frequently crashing. . After adding the new OSDs the PG count jumped fairly dramatically, but ever since, amidst a continuous low level of rebalancing, the number of PGs has gradually decreased to less by 25% from it's max value. Although I don't have specific notes, my perception is that the current number of PGs is actually lower than it was before I added OSDs. So what's going on here? It is possible to imagine that my cluster is slowly eating itself, and that I'm about to lose 200TB of data. It's also possible to imagine that this is all due to the gradual optimization of the pools. Note that the primary pool is an EC 8 + 2 containing about 124TB. Thanks. -Dave -- Dave Hall Binghamton University kdhall@xxxxxxxxxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
