-<h1><var name="TITLE"/></h1><p>Using ZFS on Linux (Ubuntu 14.04 LTS).</p>
-<h1>Zpool Import</h1><p>Because I am using a partition (sdX3) of the disks, and ZFS assumes you are using the whole disk (when it searches /dev by default), it was necessary to symlink the partition names to a new directory and zpool import referencing devices in that new directory.</p>
-<code>
-# cd /etc/zfs
-# ln -s /dev/disk/by-id/ata-ST2000VX000-1CU164_*-part3 .
-# zfs import -d /etc/zfs -a
-</code>
-<h1>Disk Replacement</h1><p>When using /dev/disk/by-id, I was unable to replace a failed disk with a new working disk when using human readable device paths (by-id).</p><p>I had to grab the numeric disk guid using the zdb command, and then use that ID in the zpool replace command.</p><p>Here disk S/N Z1E2EEN3 died, and was replaced with disk S/N Z1E77EXB.</p>
