[sheepdog] [PATCH 2/2] sheep/recovery: don't recover from local if proved not identical

[Liu Yuan]

From: Liu Yuan <liuyuan at cmss.chinamobile.com>

If we are told that the digest is not identical, we should go normal recover
process and never try to compare the digest again down the epoch track.
