So, I copied my problem I had posted from the storage section to here...
I had a disk change status to "Removed" then I decided to shut down the server, check the cables, and then turned it back on. It now seems to be "ok" except it shows a warning status of "WARNING: The volume NAS_VOL (ZFS) status is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'."
Zpool status -v reveals:
pool: NAS_VOL
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

The last disk is the one that showed "Removed" earlier... it's on ADA4.
Also, my AD0 disk has been having a few issues... it has "Device: /dev/ada0, 8 Offline uncorrectable sectors"
I've been keeping an eye on this, however this number has not increased from 8. Do I need to replace this drive? What about the ADA4 drive?
And the drive just went "Removed" again... (after about 36 hours) is this likely due to the controller or the drive? This drive hasn't shown any other signs of failure...
Any particular ways to figure out which is causing the issue?
