    ZFS Pool migration issue

    I used to have four drives in a USB DAS configured as a JBOD enclosure. It was managed as a ZFS pool in FreeNAS and served me well until I felt the itch of approaching what my storage paranoid gut felt was "full" storage.

    ZFS zfs - Filesystem-Migration - That's right?

    I'm not a newbie on ZFS but I have never used before a RAIDZ2 pool. Now I have migrated two VMs to another host. The capacity on the destination pool has grown by the factor of two :eek: I know that a RAIDZ2 setup needs more capacity but the output of "zfs list" is a little bit curious. I hope...
