Hi, my use case for Ceph is providing a central backup storage. This means I will backup multiple databases in Ceph storage cluster mainly using librados. There's a security demand that should be considered: DB-owner A can only modify the files that belong to A; other files (owned by B, C or D)...

Hello! I have created a pool + storage with WebUI. This worked well, means both pool and storage are available. In the "storage view" I can see: <poolname>_ct <poolname>_vm Question: From Ceph point-of-view, what is represented by <poolname>_ct and <poolname>_vm respectively? It's not a RBD...

Hello, In the next few days we are going to setup a small Proxmox/Ceph cluster with 3 hosts, each having 3 hdds and 1 ssd. We want to create a EC-Pool using the 3 hdd's on each host. As fas as I know we have to setup the EC-Pool using the formula: n = k + m. If we use k=3 and m=3, then the...

Ceph provides erasure coded pools for a several years now (was introduced in 2013), and according to many sources the technology is quite stable. (Erasure coded pools provide much more effective storage utilization for the same number of drives that can fail in a pool, quite similarly as RAID5...

I have decided to automate the scrubbing of my pool with the advice provided by @tom from this post ZFS Health and because it is no good scrubbing if you aren't notified of a problem looked in the suggestion at the end of that post about using /etc/zfs/zed.d/zed.rc. Information about this ZFS...
