Subject: Events Counter - How it increments
Date: Tue, 10 Nov 2020 10:24:54 -0400	[thread overview]
Message-ID: <819ff80e-10d0-8cc6-b34c-418fdea7b57a@gmail.com> (raw)

Hi everyone,

I'm new to Linux RAID. I've searched for a clear explanation on this but
couldn't find it.

How does the "Events" counter (as shown with mdadm --examine) gets
incremented? On what sort of events?

I was initially confused about the "Events" (thinking on the different
events as reported by mdadm --monitor) but I see this is another thing.
I've seen explanations about it incrementing after performing writes but
I've done some test writes and I don't see the counters changing at all
on my RAID1 arrays.  I've also seen explanations that it increments
whenever there are changes to the superblock?

Thank you.
