Re: [ceph-users] Help Ceph Cluster Down
Hi Kevin, You are right. Increasing number of PGs per OSD resolved the issue. I will probably add this config in /etc/ceph/ceph.conf file of ceph mon and OSDs so it applies on host boot.

Re: [ceph-users] Help Ceph Cluster Down
Hi Kevin, Can I remove newly added server from Cluster and see if it heals cluster ? When I check Hard Disk Iops on new server which are very low compared to existing cluster server. Indeed this is a critical cluster but I don't have expertise to make it flawless.

Hi Caspar, Number of IOPs are also quite low. It used be around 1K Plus on one of Pool (VMs) now its like close to 10-30 .

Now since ceph OSDs are running on new server cluster PGs seems to be inactive (10-15%) and they are not recovering or rebalancing. Not sure what to do. I tried shutting down OSDs on new server.
