Hello ceph community,
Last week I was increasing the PGs in a pool used for RBD, in a attempt
to reach 1024 PGs (from 128 PGs). The increments were of 32 each time
and after creating the new placement groups I trigger re-balance of data
using the pgp_num parameter.
Every thing was fine
Thats a relief.
Thank you Ilya

Hello everyone,
We had an incident regarding a client which reboot after experiencing
some issues with a ceph cluster.
The other clients who consume RBD images from the same ceph cluster
showed and error at the time of the reboot in logs related to libceph.
The errors looks like this:

this to 0.1, i would keep it at 5 sec
osd_op_threads do not increase this unless you have enough cores.
but adding disks is the way to go

I'll look into this today too.

Hello everyone,
I've been using ceph to provide storage using RBD for 60 KVM virtual
machines running on proxmox.
The ceph cluster we have is very small (2 OSDs + 1 mon per node, and a
total of 3 nodes) and we are having some performace issues, like big
latency times (apply lat:~0.5 s;
-of-object-replicas).
So if size=2 and min_size=1 then an OSD failure means blocked
operations to all objects located on the failed OSD until they have
been replicated again.

Dear ceph community,
I'm working in a small ceph deployment for testing purposes, in which i
want to test the high availability features of Ceph and how clients are
affected during outages in the cluster.
This small cluster is deployed using 3 servers on which are running 2
OSDs and 1
