All 4 disks "fail" simultaneously?
So I recently experienced a dubious "disk failure" in disk 3 of my ReadyNAS NV+ v2. A growing list of SMART errors on disk 3 prompted the NAS unit to warn me that i would need to replace the disk soon...
With the original disk 3 failure I did see many, many reallocated sectors on that disk. With the replacement as well as the original disks 1,2, and 4, the value is zero.
So last night I put the unit in "Disk Test" mode, and after completion it reported that all 4 disks are OK, and volume C has returned. The logs, however, do show the following warning:
Detected increasing command timeouts[458759] on disk 1 [ST3000DM001-9YN166, S1F0CMZQ]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
