    Size of 3 node cluster Proxmox VE with NVMe

    It's easy. You have 3/2 replication. You need 2 copies of the dataX (PG) to be ceph writable. If you don't have 2 copies of the dataX, dataX is readonly. So it depends on where are dataX placed on what disks on specific node, where disk fails.

    [SOLVED] Detect live migration from inside the guest VM

    I said, try lldpctl in VM. If it's enabled on undergoing device, you can see some info about it. But it will detect change after migration done.

    PVE GUI listen on every iface with ip so you can use this (routing, nat, etc). Or you can use reverse proxy (frontend lan, backend "wan") etc.

    Very poor storage performance in PVE ceph

    What about "rados bench" test? Power savings disabled?
  17. C

    ceph isn't meeting performance expectations

    Ceph isn't working as raid, so you can't calculate this way. Your network latency is very high, so you have (don't counting "slow" HDD) slow CPU or power savings enabled etc.
