Last week I decided to play around with Kraken (11.1.1-1xenial) on a single node, two OSD cluster, and after a while I noticed that the new ceph-mgr daemon is frequently using a lot of the CPU: 17519 ceph 20 0 850044 168104208 S 102.7 4.3 1278:27 ceph-mgr Restarting it with

[ceph-users] Total free space in addition to MAX AVAIL

I recently learned that 'MAX AVAIL' in the 'ceph df' output doesn't represent what I thought it did. It actually represents the amount of data that can be used before the first OSD becomes full, and not the sum of all free space across a set of OSDs. This means that balancing the data with 'ceph

While attempting to upgrade a 1200+ OSD cluster from 0.94.6 to 0.94.9 I've run into serious performance issues every time I restart an OSD. At first I thought the problem I was running into was caused by the osdmap encoding bug that Dan and Wido ran into when upgrading to 0.94.7, because I was

[ceph-users] Multi-device BlueStore OSDs multiple fsck failures

I've been doing some benchmarking of BlueStore in 10.2.2 the last few days and have come across a failure that keeps happening after stressing the cluster fairly heavily. Some of the OSDs started failing and attempts to restart them fail to log anything in /var/log/ceph/, so I tried starting them
