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.<br> <br> 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 redundancyâ€¦ I will have to overhaul the whole setup anywayâ€¦<br> <br> Thanks,<br> Stephan<br> </body> </html>
