Description

At the moment, when we do fsck for an EC file which has corrupt blocks and missing blocks, the result of fsck is like this:

/data/striped 393216 bytes, erasure-coded: policy=RS-DEFAULT-6-3-64k, 1 block(s):
/data/striped: CORRUPT blockpool BP-1204772930-172.16.165.209-1478761131832 block blk_-9223372036854775792
CORRUPT 1 blocks of total size 393216 B

It would be useful for admins if it reports the blockIds of the internal blocks.
