    Empty Ceph pool still uses storage

    I have just finished migrating my VMs on the cluster from a hdd pool to an ssd pool, but now that there are no vm disks or other proxmox related items left on the pool, it still is using ~7.3TiB on what i assume is orphaned data? This cluster is currently running PVE 8 with Ceph 18, but has been...

    Effects of editing /etc/pve/storage.cfg monhosts on live datastores

    I'm running a PVE 8.4 cluster. The datastore our VMs use is an external Ceph cluster running 19.2.2. Yesterday, I found a "design flaw" in our setup. In /etc/pve/storage.cfg, there's this: rbd: pve content images krbd 0 monhost mon.ourdomain.com pool pve username blah...

    Ceph NVMe-oF gateways with PVE

    I'm using PVE on three nodes, and have Ceph installed as a distributed storage on these nodes. I now want to access the Ceph storage from other servers as well, via NVMe-oF. So, what I have to do is to extend my node configuration so that the PVE nodes also act as NVME-oF targets. In principle...

    CEPH Erasure Coded Configuration: Review/Confirmation

    First, let me contextualize our set-up: We have a 3 node cluster, where we will be using CEPH for storage hyperconvergence. We are familiarizing ourselves with CEPH and would love to have someone more experienced chiming in: All of our storage hardware are SSDs. (24x 2TB NVMe, 8 per server)...

    Ceph Storage question

    Hi This seems to be the best place / forum to ask question about ceph :) My understanding of ceph is the underlying storage is OSD, these are distributed between nodes. Pools are then created that sit on top of OSD's ... i think OSD's are broken into PG and PG are assigned to Pools I think ...

    ceph Erasure Coding temporary override failure domain

    I'm recreating my ceph cluster due a configuration corruption. I will be reusing the same hardware. The problem is I don't have enough hard drives for two ceph clusters, but there is enough capacity. I know that you can't change the size of a erasure coded pool, but is there any way to override...

    Linux Bond balance-rr and Ceph Squid 19.2.1 OSD's Lost after Setting Up Bond

    Here's what I did. When I first set up the 3-node cluster I only had 1 cable for the storage network, ie. where each host is connected 10Gb/s to a switch so they can use a shared storage scheme (Ceph - to which I'm fairly new and just learning) This week we got the extra cables ordered (because...

I had a VM disks in there before I removed and when I added the Ceph pool back in, they're not showing up. I can see that the data is there when I take a look at the storage metrics and run...
