pool

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...

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...

English is not my mother tongue, so I'm probably missing some evident subtleties between several word meanings. (My final goal: using ceph storage on my 3 nodes cluster for containers and VMs) I feel somewhat confused at how are related - ceph storage - ceph pools - proxmox storage - proxmox...
