Subject: [lustre-devel] [PATCH 23/41] lustre: lov: fix layout generation inc for mirror split
Date: Sun,  4 Apr 2021 20:50:52 -0400	[thread overview]
Message-ID: <1617583870-32029-24-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1617583870-32029-1-git-send-email-jsimmons@infradead.org>

From: Bobi Jam <bobijam@whamcloud.com>

Mirror split does not increase the layout generation properly.

Mirror split does not change FLR state of the file, even when it
contains 1 mirror afterwards, and FLR state should be LCM_FL_NONE
instead.

WC-bug-id: https://jira.whamcloud.com/browse/LU-14268
Lustre-commit: ffa858b1657145c ("LU-14268 lod: fix layout generation inc for mirror split")
