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 copyi...
What happens after the failure?
Is the data lost or will it just recover after the drive is detected again? Will the volumes remain?
I have a setup with no redudancy
A Netgear ReadyNAS Ultra 2 RNDU2120 (one 2TB Seagate was included) + an additional Seagate Drive
This is configured with one raid1 volume per drive
Yes, I know I will lose half of my data in case on of the drive fails, but the data is not critical.
I need all the 4TB and I couldn't afford a Ultra 4 with raid5.
So I'm prepared to loose data in case of a real disc crash, but is my data also in danger due to this incorrectly detected disc dead?
I really hope your answer is that the volumes is just rebuilt without data loss :)
I'm not using mac. Since I added the second driver I have copied about 3TB of data back and forth within 24 hours with no problem while streaming to a media player at the same time.
I know that there are also issues with some WD discs that requires the idle time to be changed in the drive in order to wake up fast enough or else the raid functionality in the Readynas will drop drives.
But the Seagate issue is more about heavy load and not starting from idle (I suppose).
Strange that the drive is actually delivered with a seagate drive if this problem is common.
What about the fix that was somewhat promised for Q1 2012? Was that a fix in the Readynas or in the Seagate firmware?
