    [SOLVED] Proxmox Ceph implementation seems to be broken (OSD Creation)

    Preface: I have a hybrid Ceph environment using 16 SATA spinners and 2 Intel Optane NVMe PCIe cards (intended for DB and WAL). Because of enumeration issues on reboot, the NVMe cards can flip their /dev/{names}. This will cause a full cluster re balance if the /dev/{names} flip. The...

    I have a hyperconverged proxmox/ceph cluster of 5 nodes running the latest proxmox/ceph (bluestore) with 6 480GB SSD's each (totalling 30 OSD's) and I'm starting to run slow on storage.

    Ceph - Bluestore - Crash - Compressed Erasure Coded Pool

    We initially tried this with Ceph 12.2.4 and subsequently re-created the problem with 12.2.5. Using 'lz4' compression on a Ceph Luminous erasure coded pool causes OSD processes to crash. Changing the compressor to snappy results in the OSD being stable, when the crashed OSD starts thereafter...

    (Only) Windows bad diskperformance on PVE 5/Ceph Bluestore

    I am running a PVE 5-Cluster with Ceph bluestore OSDs. They are only HDD OSDs and connected over 2x1GBit bonds. Don't get me wrong here, it isn't productive yet and I don't expect any fancy performance out of this setup. I am highly impressed with the performance of it under Linux-KVMs and when...
