    About multipath and lvm

    Hello everyone, I have configured 5 Proxmox nodes to use FC multipath. The only way to achieve high availability is to mount them as LVM, but LVM does not seem to support QCOW2 format disks. I want thin disks, otherwise disk resources will be consumed quickly, but I also want HA. Is there any...

    Install containers/KVM on formatted ext4 lvm from /dev/pve/data(thin) on an SSD or NAS drive(ironwolf or skyhawk)?

    I have done this twice with a WD green and purple(both died, green was not suited for 24/7 anyways and purple was 2nd hand and I got cheap). Now I've got an SSD, where it initializes /dev/pve/data to make use of a big chunk of the SSD's capacity, so I what I usually do is make use of it via...

    Making backups small / thin as possible

    Looking for some feedback here, I recently noticed some of my backups were larger than I expected given the amount of actual data residing in the guest VMs. But I realized this is because some of those guest VMs had *previously* stored a lot of data and though I had deleted it it wasn't...
