<div dir="ltr">I have a replicate glusterfs setup on 3 Bricks (
replicate = 3 ). I have client and server quorum turned on. I
rebooted one of the 3 bricks. When it came back up, the client
started throwing error messages that one of the files went into
split brain.
<div><br>
</div>
<div>When i check the file sizes and sha1sum on the bricks, 2 of
the 3 bricks have the same value. So by quorum logic the first
brick should have healed with this information. But i don't
see that happening. Can someone please tell me if this is
expected behavior?
