Hey so I had come across an issue recently with one of my hard drives in a RAIDZ1.

The system is (running since August 30th 2013):
G.Skill 8GB dual channel kit (2x4GB not ECC) 1066MHz
Seasonic 360Watt
4x 3TB WD Red
ASRock E350M1 AMD E-350 Dual-Core

Drive #4 /dev/ada3 is showing on the alert, on the web page of the freenas box, "CRITICAL: Device: /dev/ada3, 9 Currently unreadable (pending) sectors."

Below I checked the smart status of each drive.

I am thinking I will have to be replacing at least the #4 hard drive soon, as was wondering if I should just replace it now, or is there a way to repair it to keep it up for awhile?

I was thinking of swapping out motherboards to a C2000 Xeon Atom supermicro board with 8 cores and get 204-pin DDR3 ECC and get 16 GBs. I know I will be, when I can, erasing the Raid Z1 and going to Raid Z2 as I don't use all the storage space the Z1 provides and really don't want to deal with losing my data if that another one drive or more goes out. I also thinking that running with 16GB of ECC ram will help prevent other issues occurring as I don't know if the RAM could go bad at any moment and I could potentially lose my pool.

I currently have a good backup of the data I was wondering what recommendations I could perform, like running a scrub, erasing, destroying and recreating the pool? Any help would be greatly appreciated!

Since this is RAIDZ1, I'd advise you to replace it now that the others are in good working order. It should be possible to resilver before removing the old one in your case, since you only have four drives.

I'd definitely scrub before the resilver, since you're doing this calmly.

The board only has 4 SATA ports, so ^ that's not possible.

Get an advanced RMA nonetheless and good luck. You may want to make a backup of important files with the single parity disk still in place.

Hooray for manufacturers cheaping out by not including the last two SATA channels.

Yea so I am making a second backup, I have an older one like a few days if not a week or so... Then I most likely destroy the zpool, zero out the drives, pull #4 and RMA as they are under a 5 year limited warranty and RMA it, and purchase:

Crucial 16GB (2x8GB) 1600Mhz 240-pin DDR3 ECC unbuffered
Gigabyte GA-9SISL Mini ITX Board

Total cost $600.00.
-- or --

SuperMicro MBD-A1SRi-2758F-O
Kingston 8GB 204-pin SODIMM

Total cost $472.00

Then just re-purpose my Asrock e350m1 board and non-ecc ram as a pfsense box with a dual intel 1Gbps NIC, another power supply, and another miniITX case.

I might just buy one hard drive too and then rma one and fit 6 in my Fractal NODE 304.

Thank you all for the help so far! Really appreciated it. :D

Details: C2750 boards are better for NAS than C2758 boards. C2758 is designed for stuff like routers.

Also, Kingston has acquired quite a nasty reputation lately. If possible, get something else (and always try to get the stuff listed in Supermicro's compatibility list.

Yea I know but if I get super micro which seems to have guaranteed compatibility with bsd, the issue I see is I am stuck with SO-DIMM from kingston or get this from crucial: 8GB SO-DIMM 1600MHz ECC Unbuffered

Has anybody heard of any issues or problems with the Gigabyte GA-9SISL C2750 board with the full 240-pin DDR3 DIMMs?

If you're already shelling out that kind of money and aren't scared of higher energy usage under full load, you may as well go for the ASRock MT-C224 with a socket 1150 CPU.

Alternatively you can get the ASRock C2750D4I, supports fullsize dimms, just avoid the 6 Marvell SATA ports.

You know you are right!

With an Intel Xeon E3-1226 v3, an ASRock MT-C224 mobo, and crucial 16GB of ECC DDR3 RAM I am looking at around $560.

You said the SATA are all MARVELL? So I would have to get like PCI Express SATA III card?

Could I just go with the ASRock C226 board, http://www.newegg.com/Product/Product.aspx?Item=N82E16813157466 It comes with dual Intel NICs and I think Intel 6x SATA III? That would bring the total back around $600.

Ignore Marvells _on the C2750D4I_, do not ignore the Intels on the MT-C224 and do not ignore the intels on the C2750D4I.. Ignore SATA cards. Use only Intel integrated or LSI HBAs.

The MT-C224 has 6x Intel SATA + 2x Gbe as well.
