When we move qcow2 image of a VM/guest ( from hardware tab inside proxmox gui for any VM) from local storage to shared Ceph Storage pool , does it not automatically get converted to raw format?

We have a 3 node proxmox/ceph cluster ... each with 4 x4 TB disks 1) If we want to add more disks , what are the things that we need to be careful about? Will the following steps automatically add it to ceph.conf? ceph-disk zap /dev/sd[X] pveceph createosd /dev/sd[X] -journal_dev...

health HEALTH_WARN too many PGs per OSD (442 > max 300) How can we decrease PG/OSD safely? ( though this is a ceph question)

FSYNCS/SECOND did not change much .... strangely though disk lag and load inside guest VMs were better by atleast 5 times. It was painfully slow earlier and had to wait for 20 to 60 seconds after command input , but after making changes , dont have to wait more than 5 secs for simple...

changing from none to cache=writeback in qemu guest/vm ... HW->Disk , improved the lag issue to a very good extent.

All the kvm guest/container images are in qcow2 format ..... is that causing any delay? any thoughts

Do you add following to /etc/ceph/ceph.conf ? filestore_fd_cache_size = 64 filestore_fd_cache_shards = 32 cephx sign messages = false cephx require signatures = false rbd_cache = true And then enable cache option = writeback for qemu guest/vm under Hardware/Edit Disk ? Do we have to...

Please check this and advise. Ceph cluster is running on private network with 10GBit NIC but it seems there is some lag in FSYNCS/SECOND , from what i read in other forum posts, I am suspecting this is the issue. Please advise any tips to fine tune this. Each sever runs 4x 4TB disk ...

Hi, replication size 2 servers vs 3 ( 3 node ProxmoxVE with CEPH cluster inside nodes itself ) which is better and why? Does the replication size cause the Storage Pool size to shrink ( or make available lesser space ) in size if the replication size is higher?

Can you throw some light on the following #################################################### 1) vmbr0 bridged to eth1 (public NIC ) Is there any need to use vmbr0 or we can remove vmbr0 and just set the IP directly to eth1 interface? Altough it seems bridge is necessary on public NIC...
