Hi All, We have some troubles regularly with virtual machines using RBD storage. When we restart some virtual machines, they starts to do some filesystem checks. Sometime it can rescue it, sometime the virtual machine die (Linux or Windows). We have move from Firefly to Hammer the last month. I don't know if the problem is in Ceph and is still there or if we continue to see symptom of a Firefly bug. We have two rooms in two separate building, so we set the replica size to 2. I'm in doubt if it can cause this kind of problems when scrubbing operations. I guess the recommended replica size is at less 3. We use BTRFS for OSD with a kernel 3.10. This was not strongly discouraged when we start the deployment of CEPH last year. Now, it seems that the kernel version should be 3.14 or later for this kind of setup. Does some people already have got similar problems ? Do you think, it's related to our BTRFS setup. Is it the replica size of the pool ? Have you any advice to find the problem ?
