    yes, it was… Now, yesterday I was able to shove in three new Supermicro
    storage servers. Since I wanted to re-setup that whole zpool anyway, I
    thought it would be enough just to provide a big enough LUNs (22TB) to
    the currently exhausted zpool. This 22TB LUN is provided from the new
    systems via iSCSI.

    When I tried to add that LUN as a new vdev to the pool, zpool naturally
    complained about the replication mismatch. Is it safe to do that anyway?
    I mean, the backing zpool of that LUN is also made up from 2 raidz-1 and
    I wanted to avoid actual triple-double redundancy… I will have to
    overhaul the whole setup anyway…

    Thanks,
    Stephan
