Then the 2nd disk in the *same* mirror started throwing errors! a bad moment. I had no chance of getting replacment disks until the next day so I detached the disk from the 2nd mirror and replaced the first mirror with it, converting the RAID10 to a RAID0, not ideal but the best option I had. Fortunately the re-sliver finished before the 2nd disk packed it in. Tonight I'll be adding two new disks to convert it back to RAID10.<br><br></div><div class="gmail_extra">Dog bless ZFS and its checksums, would have been screwed without them.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Both disks in a mirror failing is rare, but it can happen :) so I thought I'd brush up on my replace-brick procedure.<br><br></div><div class="gmail_extra">nb: The reduction in IOPS from RAID10 to RAID0 is quite noticeable.<br></div><div class="gmail_extra"><br clear="all"><br></div><div class="gmail_extra">Also, despite what you may have read on the internet, never use desktop drives in a server setup :)<br></div><div class="gmail_extra">-- <br><div class="gmail_signature">Lindsay</div>
