In a 5 node cluster, I had to replace some failed SSD's and now the CEPH cluster is stuck with "Reduced data availability: 40 pgs inactive, 42 pgs incomplete" Reduced data availability: 40 pgs inactive, 42 pgs incomplete pg 2.57 is incomplete, acting [1,35,14] (reducing pool CephFS_data...

Is it possible to share a CEPH WAL between all the OSD's, instead of having to partition the WAL? If I have 12 drives, I have to create 12 equal partition on the WAL, and assign each partition to an OSD. Is there a better way to assign the WAL?

I have a 3 host cluster and changed one of the hardware nodes. The new machine didn't want to boot from the proxmox OS drive, so I decided to Install Proxmox onto another drive. Before I did this, however, I removed the 3rd node (SRV3) from the cluster. Then i wanted to re-add the node, but...

Is it possible to setup a ZFS multi node cluster, like one would do with CEPH? Let's say I have 20x servers, each with 24 SSD's, and I want to use ZFS on each server. Can I have replicated storage across the cluster, so that in the event that a node fails, or I need to move some VM's off one...

Please help. I tried to change my CEPH IP's from 192.168.10.0/24 to 192.168.11.0/24, but it wen't horribly wrong. My initital setup is / was as follows: 3 servers: SRV1 - 192.168.10.241 SRV2 - 192.168.10.242 SRV3 - 192.168.10.243 I wanted to move CEPH to a 2nd IP subnet, with different network...

Hi, How do I pin a CPU core to a CEPH OSD?

I see the CEPH journal is 1GB. What is the correct procedure to make it bigger? Do I purely delete the 1G partition in fdisk, create a new one, and then specify what type? Or is there a preferred way to do it?

Hi, I wonder if someone can shed some light on this matter. The environment: 3x Supermicro server with following features per server: 128GB RAM 3x 8TB SATA HDD 2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710) 2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz Quad port 10Gbe Inter...

Hi, I am considering adding some NVME devices to a new installation of Proxmox, but cannot really see on the forums which devices are compatible, or even which are incompatible. Does anyone know where I can find a list of compatible and working NVME's? I want to use an NVME as ZFS or even LVM...

Hi, I have read just about every post on this forum on this topic. Some have some useful information, but I can't get all the answers that I have questions for, hence this post. I need to setup a 3 node high available cluster to host 14 virtual machines, Linux and Windows based. This is to...

Hi I wonder if this is at all possible: If I setup a 3 node CEPH or GlusterFS cluster and I want to dedicated a 4port 10Gbe NIC in each server for storage network. Can I set it up in such a way that I don't need a switch, but still achieve high availability? i.e. run cables from: From...

Hi all, I'm new to Proxmox, though not new to Linux or virtualization. Can someone please tell me (I couldn't get a definite answer while searching through the forums) What is the best configuration for Proxmox on 3 or 4 nodes? I need to virtualize about 12x physical servers and will be...
