Dead Disks Readynas 2100

Hi,

 

Have a Readynas 2100 with 4x3TB WD Red drives. Had a drive show up dead on Frontview. After replacing and resync, still showing as dead, and now 3 of the 4 drives are showing as dead. The logs are below. Any help on clearing this is greatly appreciated. Volumes still accessible.

Both of these aren't right.  md2 is part of your data volume (it looks like you started with 1 TB drives, then expanded to 2 TB, and finally to 3 TB).

 

md0 is the operating system, and it should be RAID-1 with all four disks.

 

I suggest backing up the data, and then do a factory default - rebuilding the NAS and restoring data from the backup.
