RN214 Healthy XRAID Drives Degrade After Every Restart
RN214 system goes to a data degraded state each and every time the system is shutdown and restarted. After the data is resynced, which takes the better part of a day, the system will once again repo...
Hi R_W , in case you never did so far it would not hurt to remove all dust/dirt from inside the box. With the nas shutdown remove the disks keeping in mind which bay each one occupied. If you don't want to conduct the cleanup effort, with the nas shutdown you could also only remove and reinsert the concerned disk to see, whether that gets any improvement.
To get more information about the error you could download the logs. The download will come as a zip-file containing lots of text documents.
(1) A look at smart_history.log might show you how often and when the ATA-errors occurred.
(2) Correspondingly in kernel.log search for the disktype and/or serial to see further information how the ATA interface is configured for the concerned drive. For example you should see something like the following:
Apr 02 15:18:13 nasname kernel: ata11: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
Apr 02 15:18:13 nasname kernel: ata11.00: ATA-9: disktype, diskserial, max UDMA/133
Apr 02 15:18:13 nasname kernel: ata11.00: 11721045168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA
Apr 02 15:18:13 nasname kernel: ata11.00: configured for UDMA/133
Good luck with fixing and kind regards
Thank you for the assistance. I removed the drives and peeked inside the box. Looks squeaky clean. I bought the NAS in late December 2018, new. I'll try the reseating of drive two and see if that helps. Thanks again.

If it's not the drives, then it would have to be the NAS chassis. If that turns out to be the case, then you can request an RMA via my.netgear.com.
Well, a new development. I moved the drive that was formerly in slot two to slot three. I then rebooted the system with drives in slot 1 and 3. The system went through the resync process. After about six hours, the system shutdown (maybe because I had the poweroff option to turn off the system on set to conserve energy (and get quiet at night)). Next, I pushed the box power on button and the system booted up, without any data degradation error and data resync. Surprised, I chose the menu option to restart the ReadyNAS. After a very short time, the system rebooted and returned to a normal state. No data degradation error, no six hour wait for resyncing.
Is it possible a single drive slot, slot two on the RN214-4, is defective and the cause of all this mess?
