From: Zac Dover Date: Tue, 14 Nov 2023 13:40:42 +0000 (+1000) Subject: doc/glossary: add "Quorum" to glossary X-Git-Tag: v19.0.0~89^2 X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F54497%2Fhead;p=ceph.git doc/glossary: add "Quorum" to glossary Add the term "Quorum" to the glossary and link to the part of architecture.rst concerning Monitors. The sticky header at the top of the docs.ceph.com website gets in the way of the location linked to in this commit, but fatigue and disgust prevent me from spending time today trial-and-erroring my way through the hostile and ill-documented wilderness of scroll-margin so that the link goes where it should.
