The Graveyard - Products No Longer Supported => D-Link Storage => DNS-345 => Topic started by: psdont on April 16, 2013, 05:30:51 AM

I installed the DNS-345 a couple of months ago after being please with earlier DNS-323 products. Before adding the drives, I updated the firmware to the current version 1.0.1. Volume_1 is setup with two WD 4GB drives in Raid 1 configuration and Volume_2 is setup with two Seagate 3TB drives also in a Raid 1 configuration. My problems began about a week ago with the first drive in the Volume_1 group was reported as failed. Presented with the option to rebuild, I chose that and all appeared to be fine after the volume was rebuilt. No reboot was performed. First indication of a problem came that night when the daily email with the stats of the volumes listed both volumes but the name for the second volume appeared as " ". Although it was still possible to access the drive, I was unaware of the potential problem to follow. After a couple of days, I began to experience network issues - after some diagnosis, it appears, the Volume_2 group was causing timeouts when it was attempted to be accessed. That night, I shut down the unit to take a further look at it in the morning. The next morning, only the Volume_1 group was recognized. The two drives for Volume 2 were only recognized as "new" drives and the only option was to reimage.
Not being a programmer, I can only assume that the problem is with the logic for the rebuild of the initial volume - it wiped the table for the data on the drives in the unit. Needless to say, the reimaging of Volume_2 resulted in the loss of data - approximately 20% of the drive was in use at that time. Guess I will leave the Volume_2 group spinning in the unit and not put any data on it until this problem is addressed.

Is there anything else you recall doing during the setup procedure that you may not have included in your post? I will forward this thread to my contact at D-Link after you've posted back with additional information.

No I think that pretty much covers what I did to get access to the second volume group (Volume_2). In short
1) Rebuild volume_1 following the "failed" message
2) Continued to operate the DNS-345 per normal (did not reboot after the rebuild)
3) Email of stats following rebuild listed the two volume groups (Volume_1 and Volume_2) but the name for the second volume was " "
4) After about 36 hours, began to experience network slowdown / outages (isolated to the network segment containing the DNS-345)
5) Shut down the DNS-345 that night as the network issues appeared to be from timeouts when attempting to access the second volume
6) Reboot the DNS-345 the following morning
7) Only Volume_1 listed - the exiting 3rd and 4th drives (Volume_2) seen as new drives to the DNS-345
8) Performed setup of Volume_2 group (note, Volume_2 was approximately 20% utilized before the problem)
Oh - there was one thing more, attempted to post to the D-Link support board but after pressing the submit button received a message that the URL was not found - that's when I posted over here.
Thanks for forwarding.

As promised, I forwarded this issue to D-Link.
Can you please perform a SMART scan for the HDDs in the RAID-1 that failed to re-validate their health?

Here are the S.M.A.R.T. scans of the drives that had been configured as Volume_2 (Raid 1) and were not recognized after the rebuild on Volume_1. I indicated above they were Seagates - those are in some of the other DNS's - these ones are Hitachi

D-Link had three questions for you:
1. HDD model name/number
2. Which HDD (slot position) was used for Volume_1, and Volume_2?
3. have you ever done hot-swap on these drives?
Also sent you a PM.
Thanks!

1) Two drives are Western Digital WD4000FYYZ-01UL1 and two drives are Hitachi HDS5C3030ALA630.
2) The Western Digital drives (Volume_1) are in slots 1 and 2 and the Hitachi drives (Volume_2) are in slots 3 and 4 (top to bottom)
3) No, the drives have not been hot-swapped. They have not been touched since being inserted into the unit.

Thanks.... ;)
