Initial edge failures are properly handled by recovering all the blocks of data. However after 2 failures in each of D20 and D272, the blocks of subsequent failures were not properly recovered. The implementation of recovery needs verification again as little testing is performed for it so firstly proper review with testing is the way to proceed.

Tested and verified for D20 setup with other related changes. Reverted commit d277a09 which should be fixed by @Sheshadri-1992
