Dead Disk.. but not really

What make/model of hard drives are installed?

Seagate Barracuda LP ST2000DL003

Do you recall what your case number with NETGEAR was?
If you do, please update the title with it.

Those are completely compatible drives with the ReadyNAS Ultra 6.

Have you experienced any of the same issues since support has accessed the unit?

Have you found any indicators of ATA errors or reallocated sectors in the logs?

Have you found any indicators of I/O errors in the logs?

1. The dead disk issue happened after the ticket was closed

2. Yes, since last weekend: Disk 1 now has 6 ATA errors, no reallocated sectors but this has happened after the disk has supposedly died (twice)

3. not sure what I/O errors are but I guess not. No other problems

thanks

ok, had the same issue again:

- experienced disk failure of Disk1 again
- took disk out and put back in, rebooted
- front view says Disk 1,3,4 all dead, RAIDAR says all disks ok, NAS display reads "Degraded Volume"
- switched NAS off
- inserted new Disk1 (replacement disk)
- power up
- NAS runs through various checks, says resynching, then "Degraded Volume"
- cannot access front view anymore
- Raidar says all disks fine
- NAS still running backup jobs in the background
- I leave it running for 2 days, no change
- reboot
- Volume now resynching
- Frontview still does not work
- 10h later, resynching completed
- Frontview still does not work, no access to shares
- rebooted
- NAS cannot find network connection
- rebooted
- same
- rebooted again
- network connection found
- still no access to data
- front view still does not work
- Raidar says everything fine
- Reboot & reinstall OS
- no change

Is there something wrong with this unit or not???
I've been running a DUO for 3+ years without any problems but I am sick of this one

Before you do any of the following, download the logs, through status > logs > download all logs (it's a link in the upper right hand side). Because if it is a chassis issue, support will be able to see it in the logs.

I would suggest that you power off the NAS and run the manufacturer's diagnostic tools (SeaTools) on the drives. Both short and long tests. If the drive doesn't pass the test, then it will need to be replaced.

If the drives come back healthy, then I would suspect that it could be a chassis issue, and would definitely open a support ticket. Upload the logs to the ticket and inform them that you suspect a chassis problem.

Hi Chris_S,
1. Don't use the HDD which has ATA errors,
2. when insert a new disk, ReadyNAS will do disk testing firstly, if it is fail, system won't do resync.
3. Replace a HDD, then cold boot ReadyNAS, system doesn't do sync if the HDD have other system partitions, it prevent user insert a wrong HDD and protect data in it, it can sync if there is not partitions on the HDD.
so you had better hot replace the HDD when system is on.

Opened a new support ticket, spent about 1h with the L2 support (getting the error msg "no network link"), now waiting for L3 support to access my system. Only the unit wont go into Tech Support mode properly: the IP address the unit displays is 192.168.11.12 while all of my IPs are 192.168.1.xxx - I had this issue before. Also, RAIDAR on my Mac can see the unit, RAIDAR on my windows PC cannot. The web interface does not work through either machine, neither is the data accessible.

readysecure1985 & evan: I cannot download the logs as the unit is totally inaccessible through the web interface. Haven't run the HDD tests (need to buy a USB chassis as all my PCs are Laptops or iMacs). But they pass the hardware test of the NAS during booting.

Have you tried a modified direct connect? Setting your PC IP address to 192.168.11.10 and directly connecting the PC to the ultra?

Hi, I have read all the post with interest as I am in similar position and getting nowhere with Tec support. I purchased the READYNAS Pro 6 and started off with 3 drives, Seagate ST2000DL003 was the choice. I setup the Nas without incident and then sent off for another 3 drives. During the delivery period 2 of the drives started playing up and reported after a while as "Dead". Seagate will not take back drives without you run their test which I did, and the drives both "Passed" but refused to be acknowledged in the Ready Nas. I opted to backup all the transferred data and do a full reset. After 1 hour both drives failed again. I did this twice more with the same reults and then gave up. I then loaded the Nas with 4 good drives and did a full reset and everything has been running fine for a week. I have sent the faulty drives back for replacement with full explanation of the problem but have yet to see if they will oblige. I contacted Tec support to ask for advice and frankly they just don't get it, and trot out the standard blurb, which is unhelpful. As I see it, the software on the NAS which checks the drives must use different test criterior to the Seagate or Windows programs. I asked Tec support for a link to the software the NAS uses with no joy. I also asked for other methods to test prior to adding drives to bays 5 and 6 and risking further problems. I have read other reports critising this particular drive model (this is since all my problems began, where were they before I shelled out?) and wonder if the Seagate ST2000DL003 should be on the HCL.
My main questions.
1: with Xraid 2 my understanding was I can start off with one drive and incrementally add others, up to the max of six. Auto volume expansion will just do it's job. How do you do this in reverse if you have a problem with a faulty drive? ie take the drive out and tell the volume to adjust itself to the new situation?
2 If that is not possible how do you test your new drives BEFORE putting them into the Raid with the same software that the Raid uses?
3: Should I take out a running drive and replace it with a different drive as a test maybe?

Sorry for such a long question but can anyone offer some realistic help and not the standard replies in the manual please?
