When an array is degraded, bit in the intent-bitmap are never cleared. So if a recently failed drive is re-added, we only need to reconstruct the block that are still reflected in the bitmap. This patch adds support for this re-adding.
Hi there -
If I understand this correctly, this means that:
1) if I had a raid1 mirror (for example) that has no writes to it since a resync
2) a drive fails out, and some writes occur
3) when I re-add the drive, only the areas where the writes occurred would be re-synced?
I can think of a bunch of peripheral questions around this scenario, and bad sectors / bad sector clearing, but I may not be understanding the basic idea, so I wanted to ask first.
