Description
In current EC implementation, the corrupted parity block will not be regenerated in time.
Think about below scene when using RS-6-3-1024k EC policy:
If three parity blocks p1, p2, p3 are all corrupted or deleted, we are not aware of it.
Unfortunately, a data block is also corrupted in this time period, then this file will be corrupted and can not be read by decoding.
So, here we should always re-generate parity block in time when it is unhealthy.
