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 report all volumes are healthy (see attached snapshots). The only error on either of the two drives is on drive 0 which shows a "1" in the ATA count. I used to use the power timer option to shutdown the system at night to save energy but stopped that due to the powerup problems with data being degraded each time. Any idea on how to stop this from happening? Thanks.

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/133Good 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.
Yup, you can download logs and attach to a Google link or similar and then PM me the link. I will be happy to take a look at them.
Cheers
That's usually caused by one of the drives not spining up fast enough. The slow one is marked dead, but then seen as alive and re-sync is started. Both your drives are 7200RPM, so it's not a speed mismatch that's causng it. Too heavy a load on the power supply.maybe?
