Update:
We got the system up and running a 6 disk ZFS raidZ-2 which can have up to 2 drives fail and still function. Curiously upon filling the array up with 3+ TB of data, 2 drives failed. ZFS worked great and there was no data loss even with the 2 failed drives (if one more drive fails a bunch of data is going to be lost). Both errant drives were checked out in a second computer and verified to be bad. One does not stay spun up and is not recognized at all, the other drops out with errors.
NewEgg claims that the bad drives have a 3 year warranty but Samsung claims the drives were sold as is with no warranty (code 101 - OEM comes up if you enter the serial number into their warranty checker).
I've made several calls to both NewEgg and Samsung over the past 3 days and have yet get permission to RMA the drives.

Hello All
I’ve made the decision to switch my storage server from FreeNAS to Solaris. I opted to use FreeNAS as it has ZFS and until BTRFS is stable, it’s the best option (IMHO) for backup and network storage.
The switch was facilitated by the USB stick that FreeNAS was on got lost during a... (1 Reply)

mlxcontrol
MLXCONTROL(8) BSD System Manager's Manual MLXCONTROL(8)
NAME
mlxcontrol -- Mylex DAC-family RAID management utility
SYNOPSIS
mlxcontrol <command> [args]
mlxcontrol status [-qv] [drive]
mlxcontrol rescan controller [controller ...]
mlxcontrol detach drive [drive ...]
mlxcontrol detach -a
mlxcontrol check drive
mlxcontrol config controller
mlxcontrol help command
DESCRIPTION
The mlxcontrol utility provides status monitoring and management functions for devices attached to the mlx(4) driver.
Controller names are of the form "mlxN" where N is the unit number of the controller. Drive names are of the form "mlxdN" where N is the
unit number of the drive. Do not specify the path to a device node.
status Print the status of controllers and system drives. If one or more drives are specified, only print information about these drives,
otherwise print information about all controllers and drives in the system. With the -v flag, display much more verbose informa-
tion. With the -q flag, do not print any output. This command returns 0 if all drives tested are online, 1 if one or more drives
are critical and 2 if one or more are offline.
rescan Rescan one or more controllers for non-attached system drives (e.g. drives that have been detached or created subsequent to driver
initialisation). If the -a flag is supplied, rescan all controllers in the system.
detach Detach one or more system drives. Drives must be unmounted and not opened by any other utility for this command to succeed. If the
-a flag is supplied, detach all system drives from the nominated controller.
check Initiate a consistency check and repair pass on a redundant system drive (e.g. RAID1 or RAID5). The controller will scan the system
drive and repair any inconsistencies. This command returns immediately; use the status command to monitor the progress of the
check.
rebuild Requires two arguments, controller and physdrive as specified in the output of the status command. All system drives using space on
the physical drive physdrive are rebuilt, reconstructing all data on the drive. Note that each controller can only perform one
rebuild at a time. This command returns immediately; use the status command to monitor the progress of the rebuild.
config Print the current configuration from the nominated controller. This command will be updated to allow addition/deletion of system
drives from a configuration in a future release.
help Print usage information for command.
AUTHORS
The mlxcontrol utility was written by Michael Smith <msmith@FreeBSD.org>.
BUGS

Error log extraction is not yet supported.
