I'll try the force assemble but it sounds like I'm screwed. It sounds like what happened was that two of my drives developed bad sectors in different places that weren't found until I accessed certain areas (in the case of the first failure) and did the drive rebuild (for the second failure). In the future, is there a way to help prevent this?
This is a common scenario, and I feel could be helped if md could be told to not drop the disk on first failure, but rather keep it running in "FAILING" status (as opposed to FAILED), until all data from it has been evacuated (hot spare). This way, if another disk became "failing" during rebuild, due to another area of the disk, those blocks could be rebuilt using the other "failing" disk. (Also, this allows for the rebuild to mostly be a ddrescue-style copy operation, rather than parity computation). Do you guys feel this is feasible?
