tl;dr shelved The original plan for 2.0.0 was to get rid of the stonith-enabled flag, but still allow disabling stonith via "requires=quorum" in rsc_defaults. Certain resources, such as stonith devices themselves or simple nagios checks, can be immediately started elsewhere even if their original node needs to be fenced. requires=quorum was designed for such resources. Setting that for all resources would make fencing largely irrelevant. That was shelved when I realized the code would have to be considerably more complicated to go that route. Also, someone could theoretically want "requires=quorum" for all resources while still wanting nodes to be fenced if they are lost. > On 2019-11-25 9:32 p.m., Ken Gaillot wrote: > > Hi all, > > > > The final release of Pacemaker version 2.0.3 is now available at: > > > > https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-2.0.3 > > > > Highlights include: > > > > * A dynamic cluster recheck interval (you don't have to care about > > changing cluster-recheck-interval when using failure-timeout or > > most > > rules) > > > > * Pacemaker Remote options for security hardening (listen address > > and > > TLS priorities) > > > > * crm_mon supports the --output-as/--output-to options, has some > > tweaks > > to text and HTML output that will hopefully make it easier to read, > > has > > a correct count of disabled and blocked resources, and supports an > > option to set a stylesheet for HTML output > > > > * A new fence-reaction cluster option controls whether the local > > node > > stops pacemaker or panics the local host when notified of its own > > fencing (which can happen with fabric fencing agents such as > > fence_scsi) > > > > * Documentation improvements include a new chapter about ACLs > > (replacing an outdated text file) in "Pacemaker Explained" and > > another > > one about the command-line tools in "Pacemaker Administration": > > > > https://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/2.0/html-single/Pacemaker_Explained/index.html#idm47160746093920 > > > > https://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/2.0/html-single/Pacemaker_Administration/index.html#idm47051359032720 > > > > As usual, there were bug fixes and log message improvements as > > well. > > Most significantly, a regression introduced in 2.0.2 that > > effectively > > disabled concurrent-fencing has been fixed, and an invalid > > transition > > (blocking all further resource actions) has been fixed when both a > > guest node or bundle and the host running it needs to be fenced, > > but > > can't (due to quorum loss, for example). > > > > For more details about changes in this release, see: > > > > https://github.com/ClusterLabs/pacemaker/blob/2.0/ChangeLog > > > > Many thanks to all contributors of source code to this release, > > including Aleksei Burlakov, Chris Lumens, Gao,Yan, Hideo Yamauchi, > > Jan > > Pokorný, John Eckersberg, Kazunori INOUE, Ken Gaillot, Klaus > > Wenninger, > > Konstantin Kharlamov, Munenari, Roger Zhou, S.
