<div>Hmm. Somehow the mirrored filesystem from another box got broken. I</div><div>have both halves, and can mount both of them in degraded mode, but I</div><div>can't put them together. Doesn't matter, once I get the data salvaged,</div>
<div>I'll build a brand spanking new mirror.</div><div><br></div><div>Anyway at the moment I am successfully copying data from one half</div><div>the mirror to a sata drive connected to the motherboard.</div><div><br>
</div><div>It appears that the only thing that doesn't work is trying to copy a whole</div><div>filesystem or large directory to a drive on the port multiplier.</div><div><br></div><div>Sent somebody out to buy a sata to esata adapter cable,</div>
