ReadyNAS 102 replace disk now problems with second one
Replaced Disk 2 in my RAID Level 1 NAS102 system and almost immediately starting getting errors on Disk 1. Not sure if I should replace second disk at this point?
After using the 2-drive NAS for years, I started receiving warnings on Feb 20 "Detected increasing ATF error on disk 2". Amassed 193 times in 2 days. On Feb 24, I replaced disk 2 with a new WD drive (same model). After install, I received "Resync finished however volume is still degraded" error. Then the log says "disk in channel 2 (internal) changed state from RESYNC to ONLINE. I did a disk test that reported "Disk test failed on disk in channel 1. Feb 25 I ran scrub and started receiving "Detected increasing ATA error count on disk 1 (109 times in 2 days). Feb 26 Scrub completed for volume date. Messages have stopped for now, but RAIDar 6.0 reports Status: "Volume data RAID Level 1, Not Redundant; 544.2 GB (59%) of 925.2 GB used", Admin page Status reads "Degraded".
Firmware: 6.10.2
OS:
Complete log file attached.Can anyone help me make sense of this?

Not Redundant and Degraded are two different ways of giving exactly the same status.
Disk 1 has failed and is no longer part of the array, and it needs to be replaced. It would be wise to back up your data before replacing the disk.

To be clear, the resync is needed to recover from the degraded status. However, there is risk - if disk 2 fails during the resync, then your data would be lost.

Yes, it appears you need to replace drive 1 and you are very lucky the re-sync completed before that drive went offline.
Thanks for your quick reply. Is it normal that the status would show different in RAIDar vs. the admin page? I don't mind replacing another disk but is there any concern that it will not be able to properly sync due to the "Not Redundant" or "Degraded" status?
