    ZFS: Storage space for zvols almost doubles when transferred to raid-z3 pool

    I'm running a ZFS raid-z3 zfs pool on a Proxmox node that serves as a backup host. I create snapshots on different Proxmox hosts with ZFS mirror pools and pull them to the backup node. I noticed that the same snapshots of zVOLs are occupying almost twice the storage space on the backup node...
