    CEPH cluster analysis and improvement

    Howdy, I have a CEPH cluster built on a former vSAN cluster. Right now, there are three nodes, although I do have three more identical servers available. CEPH is slow and I know that I am not getting any new hardware, so I would like to make it run as well as possible. Hosts are BL460G9 with...

    Ceph problem

    Hello, we have a proxmox server cluster with CEPH storage. Today one of the nodes (1/3) was crashed, we rebooted it physically but one of the VMs doesn't boot anymore because the disk is not visible in the CEPH pool. With the command rbd ls “poolname” the disk doesn't appear. Any ideas?

    Hello, We recently built a 3-node PVE hyper-converged cluster w/ ceph and I was wondering about the following: For MTU size on interfaces, does it matter where that is applied? I believe I've found that on linux bridge it is unnecessary as it inherits it from the bond, but what about the...

    Ceph 2+4 layout considerations

    Hi yall, I'm thinking about creating a Ceph pool with a EC 2+4 scheme. Even though I did intensive Google reserch, I could not find any experience with that. My idea is this: The Ceph cluster is spread across two fault domains (latency < 1 ms, 40 disks on each side, all NVME SSDs, lots of CPU...

    Ceph below min_size why not read-only?

    According to the Ceph docs, if a pool has less than min_size OSDs available, IO is blocked, that includes writes, but also reads. This seems counter-intuitive to me, does anyone know, why this is the case? Examples: Standard 3/2 pool, replicated with size 3, min_size 2: Can fully read and...

    Hi, I have a test cluster of 3 nodes, each with 2 disks : one for boot + Proxmox, the other for storage. But I want to add a shared storage to make some tests. Before going to a NAS with iSCSI, I want to try something new (for me) : CEPH So, is it possible to dedicate the storage disk of each...
