Disk Failure Detected...
I've recently purchased a ReadyNAS Ultra 6 along with 6 2 Tb Seagate ST2000DL003 disks (which are on the HCL).
I've set up the NAS in a dual redundancy X-RAID2 configuration and have starting copying all the data over the network from my old ReadyNAS NV to the new ultra 6...
About half way through copying (on 6th March), I got a disk failure detected (on channel 4). I powered down the NAS took the disk out and reinserted it, assuming there might be some kind of connection problem... When I powered back up it detected the disk, tested it and started to resync (which takes about 24 hours)... I left it alone while it did that and then it seemed to be ok, so I started copying the rest of my data across. There is nothing in the SMART+ log for disk 4 which would indicate that there was ever a problem with that disk.
A few minutes ago, I just got another disk failure (this time on channel 2). Exactly the same story... powered down and then back up again, the disk comes back to life and the NAS starts testing it and resyncing it... again, there is nothing in the SMART+ log for disk 2 which indicates (to me at least) that there was ever a problem.
After both occasions, I've downloaded the system logs from the NAS, but I'm not sure what to do with them. Is there something in the log which would show what exactly failed?
Any idea what's going on here? Have I got a couple of dud disks which need to be sent back, or is there something else going on? If they are dud, I'd need to be able to prove to the retailer that they were... the only indication I have of a problem is that the ReadyNAS ultra 6 _said_ that they had failed... but they both seem to be working fine now.
Thanks,
Ash.
P.S. Here's the SMART+ report from disk 2:

If this disk is a part of a RAID 6 volume, your volume is still protected if this is your first failure. A 2nd disk failure will make your volume unprotected. It is recommended that you replace the failed disk as soon as possible to maintain optimal protection of your volume.\n\n[Sun Mar 6 18:49:51 WET 2011]

- The suggestions you made didn't seem to apply to my device. My NV+ V2 didn't have those options available anywhere.
Anyway, i'm using a ST33000651AS, ST3000DM001, and HDS723030ALA640. All of which are on the HCL of course. I've verified them with the manufacturer diag tools with the advanced/long tests. I had to warranty one of the drives because of a diag failure so i've been waiting on the new disk. But now they're finally all good and pass the tests.
I am still getting the random drive fail issue though. I contacted netgear support and they suggested i do the OS reinstall on the device. I thought that worked because after resyncing, it never sent me an email about a drive issue. After i got home from work, i was all excited to find that the drives still listed as redundant and active. But about 10 seconds after accessing the Health page, Drive 1 flipped to inactive and failed.
I'm assuming that this means that the drive went to sleep or went into a power-save mode, and due to inactivity the NAS had not checked it until i called up the Health page.
Is it possible that ReadyNAS is completely intolerant of having to wait for a drive to spin up?
I've warrantied the device once, factory reset it who knows how many times, replaced and tested all the drives, and ran the OS reinstall. What else could it be? - Hi,
I too have a NV+ V2 and constantly get a drive reported as "dead". I have 4x 1TB drives either WD or Seagate and a simple re-boot will normally restore all the NAS drive(s) to operation. Sometimes I can go a week or two without any "failures" and then it will happen to drive 4 and the next day to drive 2. When the drive dies the system reports the array as non-redundant until I re-boot and then it seems happy again. Sometimes it will re-sync and sometimes not, no real pattern that I can detect.
Like everyone here I suspect the NV+ V2 of intolerance when waiting for a drive to spin up after "sleeping" but....
This weekend I am planning to do a factory re-set and begin the long process of restoring, but I'm loosing faith with my V2 system. (incidentally I have a V1 NV+ that works a dream and has done for years, so I am a little disapointed to experience so many problems with the V2) I was hoping for more. bokvast wrote: Got an answer from a l3 that they are working on a fix and it is expected to arrive in Q1 2012
Soon Q1 has passed without a fix being released. I have installed the latest update but no luck - the problem persists on my Ultra 2.
I have got a feeling that the error only exists on some layers - for instance the leds on the front panel light up as if both disks are online and redundant, and each time I remove the faulty disk, shut down, replace it and power up again I receive the status message "Data volume will be rebuilt with disk 1". Still the Frontview displays the disk as dead.
When I connect the drive to my PC it is possible to access without problems...- Does the disk pass both short and long SeaTools tests?
- I spoke with support last night and after about 30 minutes of discussion, the L2 tech concluded the same as I did, that there is some sort of software/firmware issue.
The only problem he can see is that when the device or drives go into a power saving mode, it does not give them enough time to spin back up before claiming drive death.
He escalated my case to the developers/engineers. So now I'm just waiting. I'll let you all know when/what i hear back. mdgm wrote: Does the disk pass both short and long SeaTools tests?
My disk? I have not tried to run any of them. Should I?mdgm wrote: Does the disk pass both short and long SeaTools tests?
I've tested the disk now, and it passed both short and long SeaTool as well as WDC tests without detected errors. It still shows up as 'dead' in Frontview.- PiddeP
If you have owned the Ultra for less than 3 years, you should still be covered under hardware warranty, and you should contact support with this issue. If you have owned it for longer than that, I would still recommend using the email support option to get the issue resolved. readysecure1985 wrote: PiddeP

I've contacted support now, they responded with some tips that I had already tried and said that I should keep an eye open for new firmware updates...
But as Q1 ends today it should be a short wait :/- I too was receiving drive failures on my Ready NAS, they were alternating between drive 1 and 2. This started about a week after initial setup of my NAS in early March of this year. I have since switched it over to Flex-raid and I have not received any drive failures in the past month.
