You just tell the installer to use ZFS, choose 2 drives, and you get a mirrored ZFS root.</p>
<p>I hope this feature will make it to Solaris 10 update 6.</p>

have several already and which we can build new instances of in under an
hour. Often we have a full <code>dd</code>'d image of the first drive on the second
drive, so we can recover from a drive failure even faster if we're okay
with having to apply pending updates or the like again.</p>
<p>(There are also a number of non-essential servers that we only have one
of but could take a while to rebuild without anyone really caring.)</p>
<p>Note that there is no strong guarantee that a typical running system can
survive a drive dying; a lot depends on just how the drive decides to
die and what else its creativity manages to take with it. (Although I
believe that life is better than back in the days of shared SCSI and
IDE channels.)</p>

This has been a failure in the Linux distro installers for quite a while now. But, for some reason this post really annoys me. The fact that you have systems that aren't mirrored simply because someone was lazy?</p>
<p>Perhaps I'm being optimistic by thinking that because doing something is hard, but the correct thing to do that the person would put the effort into it (particularly if it's a one time thing). Or perhaps I'm being overly judgmental, but I was really taken aback when I read this.</p>
<p>Sure we all have deadlines and tight budgets to follow, but this is really cutting your toes off so your shoes will fit.</p>
<p>Thanks for all your posts and please ignore the trolls (like myself) who feel compelled to comment without all the information. :)</p>
