 +==== Import ====
  
 +The update repository appears to be broken, so I might need to re-install the OS on hydra.  According to a post I found, all I need to do is "import" the pool.
  
 +  * [[http://forums.freebsd.org/showthread.php?t=16807]] <- a couple posts down
 +  * With all drives installed and spun up: <code>
 +zpool import
 +</code>
 +  * Just import your pool now! <code>
 +zpool import <poolname>
 +</code>
 +
 +<code>
 +With all of the drives in the system, just run zpool import.
 +That will scan all the drives for ZFS metadata, and will show any pools that can be imported.
 +Then you just import the one you want via zpool import <poolname>
 +</code>
 +
 +==== Update ====
 +
 +AH, would make more sense to use a these drive IDs since it would be consistent:
 +
 +"You should add your drives using the /dev/disk/by-id directory.  That way the drive will be picked up consistently regardless of the device node in /dev/. "
 +
 +==== Drive Failure ====
 +
 +  * **2013.09.30** - Looks like we might have had a drive failure.  I know in the past, one of the drives was flaky and would not show up because of a cable issue (swapped cables, and it worked).
 +  * Drive identification: (just pasting in the drives in the raid alive<code>
 +# status as of today 2013.09.30
 +#sudo zpool status -v media
 +
 +  pool: media
 + state: DEGRADED
 +status: One or more devices could not be opened.  Sufficient replicas exist for
 + the pool to continue functioning in a degraded state.
 +action: Attach the missing device and online it using 'zpool online'.
