From: Ilya Dryomov Date: Wed, 1 Mar 2017 16:33:27 +0000 (+0100) Subject: libceph: don't set weight to IN when OSD is destroyed X-Git-Tag: v4.11-rc2~11^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b581a5854eee4b7851dedb0f8c2ceb54fb902c06;p=platform%2Fkernel%2Flinux-exynos.git libceph: don't set weight to IN when OSD is destroyed Since ceph.git commit 4e28f9e63644 ("osd/OSDMap: clear osd_info, osd_xinfo on osd deletion"), weight is set to IN when OSD is deleted. This changes the result of applying an incremental for clients, not just OSDs. Because CRUSH computations are obviously affected, pre-4e28f9e63644 servers disagree with post-4e28f9e63644 clients on object placement, resulting in misdirected requests. Mirrors ceph.git commit a6009d1039a55e2c77f431662b3d6cc5a8e8e63f.
