One of my drives in my freenas server appears to have had some problems and has been kicked out of the pool. I'm trying to run smartctl on it but I can't find it.

Hardware:
1. Motherboard: ASUS P9D WS
2. CPU: Intel i3-4150
3. RAM: 16GB ECC
4. Hard Drives: 1x USB used for OS (see below)
6x 2TB ST2000DM001-1ER164 Samsung drives
- all 6 samsung drives are directly plugged into the motherboard sata ports
5. Build: FreeNAS-9.3-STABLE-201504100216 (with all current zfs flags installed)
6. ZFS Pool: RAIDZ2

I saw that there was an alert in the GUI interface so I ran zpool status and got:

Code:
[root@freenas] ~# zpool status
  pool: Base
 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.
  scan: scrub repaired 0 in 0h28m with 0 errors on Mon Apr 13 20:08:13 2015

I then ran zpool clear and rebooted, and now I get:

Code:
[root@freenas] /dev# zpool status
  pool: Base
 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'.

Next step would be to run smartctl commands on it, but I can't find the disk anymore (should be 6 drives, on on scbus5 I imagine):

Code:
[root@freenas] /dev# camcontrol devlist
<ST2000DM001-1ER164 CC43>          at scbus1 target 0 lun 0 (pass0,ada0)
<ST2000DM001-1ER164 CC43>          at scbus2 target 0 lun 0 (pass1,ada1)
<ST2000DM001-1ER164 CC43>          at scbus3 target 0 lun 0 (pass2,ada2)
<ST2000DM001-1ER164 CC43>          at scbus4 target 0 lun 0 (pass3,ada3)
<ST2000DM001-1ER164 CC43>          at scbus6 target 0 lun 0 (pass4,ada4)
<SanDisk Cruzer Blade 1.27>        at scbus8 target 0 lun 0 (pass5,da0)


and

Is the disk totally dead, or do I need to take it out and work on it in another computer? The data is backed up elsewhere as well.

You can try a new cable and Sata port, but a new drive will probably be in order.

Your welcome. Now, I didn't know everything and I'm not an IT professional. May want to see what some of the more experienced guys chime in and say. Good luck.

I'll definitely keep an eye on this thread, but given the drive isn't appearing in the list of devices at all after a reboot means something is pretty bad. I'll have to pull the server out and start tracing sata cables (and marking things for next time) but that'll occur tomorrow so I'll see what else is suggested.

The drive should still be listed by camcontrol -devlist

If not, it really died.

I plugged it into my linux workstation and it powers on, makes some noises and then powers itself off without the linux kernel detecting it. Time to get it RMA'd. Thanks for the help :)
