Hi There,
Can you conform the below scenario in which blocks are consider to be
a "bad" block.
1. A read error on a degraded array ( a state of raid when
array experiences the failure of one or more disks)for which the data
cannot be found from other legs is a "bad" block and gets recorded.
2. When recovering, from source to target leg, for any reason
if unable to read from source, the target leg's block gets recorded as
“bad” (thought the target block is writable and can be used in future).
3. Write to a block fails (Though it leads to degraded mode).
Are they all implemented and is there any other scenario?
When exactly the raid1 decides to make the device "Faulty"? Does that
depends on the number of bad blocks in the list ie: 512?
What is the size in the metadata for storing the bad block info.
Thanks,
Ankur
