Subject: mgr/DaemonServer: skip adjusting pgp_num when merging is in-progress
X-Git-Tag: v15.1.0~1645^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=39f15bb2bed35dda91b1b94c26b23c8951fedac5;p=ceph.git

mgr/DaemonServer: skip adjusting pgp_num when merging is in-progress

otherwise there is a possibility we might change the up set of the
merge participants and hence have to back off the merge process.
Also this will cause some other (racy) corner cases that are hard
to take care of.
