Hello,
I noticed that commit/apply latency reported using:
ceph pg dump -f json-pretty
is very different from the values reported when querying the OSD sockets.
What is your opinion? What are the targets the I should fetch metrics
from in order to be as precise as possible?
Hello,
after rebooting a ceph node and the OSDs starting booting and joining
the cluster, we experience slow requests that get resolved immediately
after cluster recovers. It is improtant to note that before the node
reboot, we set noout flag in order to prevent recovery - so there are

Hi,
I have just expand our ceph-cluster (7 nodes) with one 8TB HGST (change
from 4TB to 8TB) on each node (and 11 4TB HGST).
But I have set the primary affinity to 0 for the 8 TB-disks... in this
case my performance values are not 8-TB-disk related.

Yes: clients need an MDS key that says allow, and an OSD key that
permits it access to the RADOS pool you're using as your CephFS data pool.
If you're already trying that and getting an error, please post the caps
you're using.
