ReadyNAS Pro - Drive dead, replaced drive and 'dead' again?
Evening all,
I was alerted by the ReadyNAS unit late yesterday that 'Drive 2' was 'Dead', I thought this a little odd as it was a relatively new Seagate 2TB ST2000DL003 drive but picked up a brand new drive to replace it with this afternoon (again, a ST2000DL003). I replaced old drive with the new and nothing happened. The ReadyNAS didn't recognise the new drive (as, from memory it has in the past) and didn't start the rebuild the volume, no status updates on the LED etc. So i powered down the ReadyNAS and rebooted it. This time is recognised that Drive 2 had changed, reported it was checking the disk then reported that "Data volume will be rebuilt with disk 2.". However about a minute or two after this, in both the RAIDiator and Frontview, the drive is reported as 'Dead'...
It cant be the brand new drive, so is something else amiss here? The drive never had any reported 'reallocated sector errors' either. A hardware problem with the ReadyNAS perhaps?
I'm running a ReadyNAS Pro Business Edition, with 4.2.19 version firmware.
Any help most appreciated as this is a little worrying to say the least. I have downloaded the logs if they may help.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
I just had this same problem yesterday. Drive 6 was reported as dead. I purchased and installed a new drive. It was scanned for errors, and then the RAID was rebuilt.
The log indicates the rebuild completed successfully. However, the same drive is now reported as "dead" (and in the drive list it has the type of the previous drive (a WD), not the current drive (a Seagate).
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
Strangely I'm having very similar issues with my NVX Pioneer edition. Got 4 of the ST2000DL003, and of the 4, only one is working. The front panel just tells me that the new drive is being checked, and I have a log full of 'Data volume will be rebuilt with disk 2", but after more than 24 hours, I suspected that the rebuild wasn't going to happen. I plugged back in the Samsung HD154UI drive, and it rebuilt in about 8 hours. I have the latest firmware (4.2.19), so I'm suspecting that even though they are on the Compatability List, maybe the Seagate ST2000DL003 and the ReadyNAS lineup are not playing nice together.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
Can someone in support comment on this? I have a brand new Ultra 4 plus and put in 2 of the identical drives - new seagate ST2000DL003 2T and after only a week, I suddenly get advice that one disk is dead. I powered down, pulled out the (supposedly) dead drive, put it back in again and powered up. voila! It's apparently 'live' again and doing a complete resync, but now after reading these I'm concernded. Is there a problem with the NAS ultra series or the drives? Frontview is also performing very slowly - and this is from someone who has just upgraded from the original DUO!
I have a spare - but dont believe that one is dead. Its only a few months old (it replaced another that said it was dead - but a reformat and its working fine in my pc...)
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
mdgm is providing the best path here. I would like to second the motion of checking the drive with SeaTools. It is not entirely uncommon to find a batch of bad drives, and yours could possibly fall victim to such a thing. SeaTools should verify whether or not it is a dead drive.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
mdgm is correct, and what you are seeing is expected behaviour. I wanted to add that for anyone who completes the short and long tests using the manufacturer tools and the drive passes, I would recommend you open up a support case so we can review your unit.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
I put the 'dead' disk back in today. 7 hours later and it has synced with no errors.
I'm really not trusting the 'dead' alert. I didnt even get any alerts about dead sectors either - just fine to dead. And now reborn! I guess it is Easter....
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
Look the NAS would've marked the drive as dead because it repeatedly failed to respond. Checking the disks using vendor tools will help confirm if the drive is actually bad.
Most of the time the NAS gets it right. A disk it marks as dead is actually having problems. Disks can fail without any warning from SMART data. It's possible the disk may be just failing.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
Ok, so now on another thread, support people are saying its a problem with spin down on ST2000DL003 seagate models. If so, why is it on the HCL (I've just purchased 2!!). If not, why are we saying here it is a problem with the drives? Can we get a consistent answer please? And in the interim should I disable spin down? (seeing the other thread states this is a causal factor).
Netgear have always stressed the need to purchase drives on their HCL - I'd be very disappointed to here backtracking on this model.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
well - BIgleps - lucky you - you purchased only 2 pieces - i bought 5 pieces. 😜 Its obvious that there is a problem with this combination of hard drives & NAS. The netgear support team is not even willing to answer my request in this thread. http://www.readynas.com/forum/viewtopic.php?f=20&t=62328
Unfortunally trusted i the official information on the hardware-comp-list and have now 5 useless disks, NAS and hours - no days - of wasted time to get a working backup for my little company. Now i will contact the reseller and hopefully i can send this netgearproduct back. With this experience in memory i will never ever trust a Netgearproduct.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
I see others using other devices are having similar issues.........Just FYI......I have been using six (6) identical ST2000DL003 2TB drives in my ReadyNAS Ultra 6 for over a year and have never had any problems with the drives being reported as dead. I DO NOT "Enable disk spin down after X minutes of inactivty" in the Power tab under System in Frontview. Not sure it this helps you out or not, but I wanted to confirm that the ReadyNAS Ultra is compatible with the ST2000DL003 2TB drives.
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
I'm also having constant problems with Seagate drives being reported as dead. I have the NV+ V2. I've had it since january and it worked for a maximum of 6 days before reporting dead drives. On average it lasts about 4 hours after a resync before declaring a dead drive.
I've had an escalated support ticket open with netgear for over a month now with no resolution. Supposedly 3rd level support is trying to replicate the issue but that was a week ago.
While yes your drives may have had issues and running Seatools to check for bad sectors is a valid concern, it's likely you are suffering from the same issue i do.
I'm fairly certain that it's some sort of spin-down/spin-up issue with Seagate drives. The last time i had it fail, it failed about 10 seconds after i called up the dashboard's Disk Health page. So that leads me to believe that the disk spun up too slow for the system and it declared it dead. 2nd level support agreed with me, but 3rd level support has yet to provide useful feedback.
I'm almost on a first name basis with the 2nd level peeps now. :lol:
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
I am having almost the same issue with a brand new NV+ v2 and 4 equally brand new Seagate 2 TB Barracuda Green ST2000DL003-9VT166 drives. A couple of days ago, the front panel started to report "Disk 2 Failure", but neither RAIDar nor the Web Interface report a disk failure and the drive seems to work just fine. The error even disappears on its own again.
Can anyone confirm this is a known issue that will be resolved, else I'm tempted to take it safely and return the NAS?
Re: ReadyNAS Pro - Drive dead, replaced drive and 'dead' aga
There is a known issue with this model drive.

You had batter not use ST2000DL003, Seagate has "FLUSH CACHE EXT" hang problem on the driver, the symptom would be exactly same as described: Entire disk(all partitions) not responding, only power cycle can bring it back. Seagate recently admitted this issue, they have a test firmware to address this hang issue.

Yeah, and I have purchased 6 of those Seagate Barracuda Green 2TB drives, not even counting the replacement I got for the first one that died... I'm using the Ultra 6 as well as the Original Poster.
I really need to get this resolved asap, the ReadyNAS is almost new, bought in February, while a friend of mine has had the exact same make and model, with 6 Seagate Barracudas, working perfectly, not even having to reboot for a year!!! Because of this I haven't lost faith in the product itself, but I need a way to sort this out, so I can use the NAS for its indended purpose. I'm currently transferring all data to external usb-disks to prevent data loss, since I no longer have any drives to replace dead disk with. And when that is done I don't know if I'd dare to put it back to the NAS...
