Subject: [RFC] md raid resync counter
Date: Fri, 01 Nov 2013 13:59:40 +0100	[thread overview]
Message-ID: <5273A5BC.5060109@gmail.com> (raw)

Hi Neil and all,

Is there anyway to know:

1. How often does a raid start to resync?
2. How many bytes did it resync?

If not, for the first one, I think we cound add field into mddev like
resync_counter, increase when resync done, and annother field into
md_rdev to track how many bytes synced to the outdated disk?

Regards,
Jack
