The Graveyard - Products No Longer Supported => D-Link Storage => DNS-323 => Topic started by: njphones on June 10, 2010, 08:54:16 AM

I have a DNS 323 with two Seagate Barracuda 7200.12 - hard drive - 1 TB - SATA-300 that I bought new.
My Raid1 keeps failing-shows a status of Degraded. I have to continuously reformat and rebuild my dives. I have the latest firmware-1.08. It happens regardless of choosing best performance or most stable. It used to happen every couple of months, now it seems to happen every few weeks.
It is a persistant problem that has me baffled and I was wondering if there is a fix for this or something that I can try to troubleshoot. The problem is getting worse.
-
I'd try replacing the drive that keeps failing.......
-
I would turn off the NAS, remove the drives and insert them direct in a PC and use Seatools to test them both.
You might also want to try resetting the NAS to factory defaults.
-
I do not think that it is the drives-they were brand new and the odds of getting two bad drives? Also, I have tried switching the slots (after reformatting) and the problem happens in either slot, on either drive. I noted each failure and what drive failed.
If I restore the unit to factory defaults, would I need to upgrade the firmware afterwords?
-
No need to re-flash the firmware after a reset.
I'm not sure switching hard drives in a RAID array is a good idea ?
Could be bad batch of disks if they were purchased at the same time.
:)
-
I switched them after they were reformatted as single disks.
After reading some posts here I am considering going to two individual disks and abandoning the Raid 1 all together. Instead I would just back up Volume 1 to Volume 2.
This appears to be a better solution because I would not have to worry about the Raid 1 degrading.
Is there a reason not to do this?
-
The only thing that RAID-1 brings to the party is enhanced availability of the data. Separating them and doing duplicate copies is better backup than RAID-1.

Clearly you won't get any RAID degraded errors if you're not running a RAID, but Id be concerned as to why the NAS thinks there is a problem with your drives. Hence the disk check suggestion...

I believe you. In fact, it was reading your posts that convinced me.

I agree with Jamie on the problem isolation. I ran my DNS-323 in RAID-1 for over a year, so with good drives it should work fine that way.

I guess it is my opinion the the issue is with the unit and not the disks. If I eliminate the Raid issue and the disks fail then I know it is not the unit.

Good point, I will run the tool on my disks.

Make sure you have another backup ;)

Okay, so today I turned my DNS 323 on and here is what is says on the Status Page:
Total Drive(s): 1
Physical Disk Info
Slot Vendor Model Serial Number Size
Right Seagate ST31000528AS 6VP05Q6H 1000 G
Left Seagate ST31000528AS 6VP0481K 1000 G
This makes no sense at all. Additionally, both status lights on the unit are steady blue indicating that 2 disks are inserted and functioning.
I had built a raid configuration, but it is gone!
-
Hope you have good backup. :)

I thought you decided to use two separate disks? Did you check them?
-
I do-in fact I have 2 good backups on external HDD.
I was going to do it today, I just turned on the unit to stat the process.
I rebooted again and not it says:
Total Drive(s): 2
Volume Name: Volume_1
Volume Type: RAID 1
Sync Time Remaining: 159.3 minute(s)
I have a feeling that I will not be reccomending this product anymore. I just don't feel that it is stable.
