BitRot Protection Failure - Anything To Be Done?
12:37:25 AM 01/21/2015 Bit rot protection has detected a silent error within /data/FileHistory/Home/C52893-G/Data/$OF/18143/18144 (2015_01_15 11_11_06 UTC).jpg on /dev/sdc3 and cannot correct the er...
On other threads Jeff indicated that he is only using the EARX drives temporarily - WDC Reds or Pros are in his future.
I'd replace any drive with pending sector counts > 50 (generally I replace them when the reallocated sector + pending sector counts reach the 20s).
fwiw, I'd still say this is worth looking at. RAID and bitrot protection are all about repairing damage when things go wrong. There's no need for RAID if you have healthy disks. Here we have some bad disk events that should have resulted in a normal RAID repair, and we get what appears to a be a false positive detection of bitrot. If it were my code, the first thing I'd suspect is that I had a bug - that somehow the RAID repair and the bitrot detection collided.
