freenas-boot i/o error

[rwfitzy]

I have screwed up the boot. I use two innodisk SATADOM-SV for the boot mirror, I saw a DEGRADED message in the GUI and did a reboot to see both SATADOM in the BIOS POST, but the GUI still reported DEGRADED. The boot pool status showed one drive as UNAVAIL, so I detached in an attempt to reboot and see if it was seen afterward, but the reboot was unsuccessful. Here is the screenshot of the error received when trying to boot now:

Worse case, I'll go down to the data center tonight to replace any problem SATADOM, re-install and restore a backup of settings. Would that be the only option at this point? This system is a Supermicro X6DHT-G with 32GB of RAM.

Would that be the only option at this point?

Probably. I've actually lost a SATA DOM before. I had to replace it.

I wouldn't have rebooted the system while it was in a degraded state either.

It rebooted the first time without issue until I detached the UNAVAIL device and rebooted. I could I correct the problem without a reboot?

So, I replaced the SATADOM I believe was bad and did an Upgrade using CD with a fresh install of boot environment, selected my ada6 and ada7 devices. Now, the system is back with all my settings, but boot is still DEGRADED as it was:

Code:

root@nas1:~ # zpool status freenas-boot
  pool: freenas-boot
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'.

            ada6p2               ONLINE       0     0     0

errors: No known data errors

What would be my next step to try? If I go into the GUI, there are no devices listed if I choose to REPLACE.

At this point I'd probably just back the config up and do a fresh install.

Yes, I did a fresh install this morning and now all back to normal.
