Description

OM is pre-allocating too much blocks for EC keys.

Assume the replication config is rs-3-2-1024k

KeySize	PreAllocatedSpace (Expected)	PreAllocatedSpace (Current)
1 MB	blockSize * 5	blockSize * 5
blockSize + 1 MB	blockSize * 5	blockSize * 5 * 2
blockSize * 2 + 1 MB	blockSize * 5	blockSize * 5 * 3
blockSize * 3 + 1 MB	blockSize * 5 * 2	blockSize * 5 * 4
