    Number of disks on Ceph storage?

    Currently, I have 1 disk in each server(total 3) used for Ceph shared storage. I noticed that if 2 out of 3 disks are not working then complete ceph will also stop working. I am not sure if the same (n/2 +1) formula works here as well. Why It is concerning is because we are using CephFS as...

    last missing enterprise feature (on shared block storage / SAN)

    Hi, I know that there is already "LVM over iSCSI/FC" for shared block storage (SAN) which carves out LV from a shared VG/LUN for individual VM disks - but with no snapshot and thin provisioning support my question is why is there no (extended) storage plugin which provides 1.) "QCOW2 over/on...

    Proxmox, Fibre Channel, and 3PAR

    Hello. So I've gone through what I think are the docs regarding PROXMOX and fibre channel presented LUN's. I'm using an older 3PAR 7200 in my lab, attempting to get shared storage between a PROXMOX cluster. So far, I have a fully operational cluster with a shared NFS volume, which performs...

    [SOLVED] What happens when one of the raided disks dies in a 3-server HA system?

    Indeed, Proxmox will not work when 2 out of 3 disks die in shared storage. My question is what happens when 2 disks in servers are RAID 1(shared storage) and one of the disks from two servers die? Will the Proxmox server use the raided disks or will it die?

    [SOLVED] Cehp degraded and did not add back automatically.

    We had an issue and removed one out of 3 disks used for HA. The system is working fine, but when we tried to add the disk back. Ceph shows drive 'in' but it is not adding it to the pool automatically for read/write. I pressed 'start' and checked the log which shows '33.333%' degraded. Used CLI...

    Recommends for storage type to Synology NAS

    We have PVE running, with VMs and Containers running over NFS share to our Synology. We mostly leveraged VMs, so at the time I hadn't realized that Snapshots on NFS for containers would be an issue. Now I am starting to use LXC more often and would like to be able to have snapshots. The options...

    What about LVM+qcow2

    Hi, This is an idea that makes a lot of sense to me, yet I'm not able to find people talking about it so it's probably a bad idea. Still I would love to know why it's bad. Before anyone asks, no I'm not planing on using this in production. According to the docs PVE supports shared LVM storage...

    NFS Shares on shared network storage

    Hello, I'm setting up a new proxmox server for myself (homelab). I am in the process of adding a synology share that I had setup on my old lab and i'm wondering which option(s) would I need or recommended to just give read access to my proxmox server in the Content drop down? Thank you.
