I recently had a HDD failure on a SW RAID1 system (Debian 6.0) and what happened was that the active HDD looked like it had some badblocks which somehow propagated to the HDD that was still OK but it was set as spare and couldn't synchronize. This basically is my assumption as I cannot say for sure.
I was wondering if any of you knows if it is possible that the errors from a broken HDD to propagate to the other HDD and if so if there is any setting for something like this not to happen?
Any insights on this matter would be greatly appreciated. Thank you.
