</div>So let’s look at the two drives you’re trying to work with:<br>
<br>
WD1600BJKT (c4t13d1, your boot disk)<br>
WD2500BPVT (c4t14d1, the mirror you want to add)<br>
<br>
Looking up those drives (WD Scorpio Blue and Scorpio Black models, respectively) shows that the WD2500BPVT has WD’s “Advanced Format” on it - ie, sector size is larger than the traditional 512n which which what the WD1600BJKT has. The Advanced Format is denoted in the drive model number with the “PVT” suffix.<br>
<br>
Because of this, zfs will refuse to try to meld the drives together into a mirror. You will need to replace the WD2500BPVT with a WD1600BJKT to match your existing one, or at the least make sure the drive is formatted with 512k sectors and not something larger.<br>
<span class=""></span></blockquote><div><br></div><div>ok, clear, but the question remains: how do I achieve that (so I do not have a WD1600BJKT, and want to format it with 512k sectors) in omnios? Is it possible or do I just need to reinstall (I do have 2 WD2500BPVT disks, so that is possible; a pain, but possible).<br>
