Subject: rbd-mirror: do not run pool replayers against TX-only peers
X-Git-Tag: v15.1.0~175^2~6
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=73a0be9ac1efe61bfcd08c29a23d26b0a23b28aa;p=ceph.git

rbd-mirror: do not run pool replayers against TX-only peers

Now that we track RX and TX states of peers, any peers that are
listed as TX only should be excluded from image replaying.
