RN314 and high ATA error count on 2 disks
I have a RN314 and I've got high ATA error counts. I have two RAID 1 volumes, each 2x3TB disks. One disk in each volume has been reporting increasing ATA counts. Disk: Detected increasing ATA e...
UNCs and Reallocated Sectors definitely point to the disk. ATA errors relate to the SATA bus, so can either be an issue with the NAS or the disk.
I was copying from vol2 to vol1 and in the evening, disk 4 was removed from the array on vol2, but also now vol1 shows the first disk as status unknown, so that's probably failed too - I did see some disk logs showing the disk test status as failed - odd that it's not recognised as failed and therefore degraded the volume.
Anyway, I have almost got all data from vol2 to 1 and then I'll remove disk 1 and swap disk 3 to disk 1 and vol1 data onto the other disk,
Will I need to clean disk 3 before I put it in as disk 1?
I also set up rclone last night and did a sync to google drive with one of the important volumes, so have backed that up ok - although I do have other backups, nice to keep as many as possible
