Re: Migrated to corosync 3.x knet become default protocol

Hi Sathish, apology for the super late reply.

In fact, knet should make it easier. corosync will continue to use the same authkey and load it into knet. knet and corosync, in recent versions also allow runtime change of the authkey without shutting down the cluster and restart. It should be possible to update authkey and issue a config reload for corosync. This feature requires all nodes of the cluster to be online. > > https://access.redhat.com/solutions/5963941 > <https://access.redhat.com/solutions/5963941> > > https://access.redhat.com/solutions/1182463 > <https://access.redhat.com/solutions/1182463> > > We shouldn't end up in a case where Pacemaker stops working due to some > certificate/key expiry? No, that won´t be the case as knet and corosync use a different encryption method than pacemaker.

kronosnet v1.22 released

by Fabio M. Di Nitto

All, We are pleased to announce the general availability of kronosnet v1.22. *** This release includes several MAJOR bug fixes and we strongly encourage everyone to update as soon as possible *** kronosnet (or knet for short) is the new underlying network protocol for Linux HA components (corosync), that features the ability to use multiple links between nodes, active/active and active/passive link failover policies, automatic link recovery, FIPS compliant encryption (nss and/or openssl), automatic PMTUd and in general better performance compared to the old network protocol. Highlights in this release: * Fix incorrect defrag buffer index that can cause knet to stop processing all traffic under some extreme network conditions (random latency). * Increase defrag buffer size to better deal with extreme network conditions as above. * Do not leak resources if link configuration fails * Major rework of ACL code to match API vs implementation. * Detect incorrect link configuration when mixing static and dynamic links * Fix knet_send_sync API to require a destination filter * Fix knet sockaddr_storage size across the board to deal with newly introduced checks on FreeBSD * Minor docs updates * Major internal test suite fixes Known issues in this release: * Preparation for this release spotted a long standing issue with SCTP transport used in combination with dynamic links. This specific issue has been in the code since SCTP has been introduced. It will be addressed in one of the upcoming releases. The problem does NOT affect the corosync / High Availability use case.

Old pcs-0.9.167/0.9.168/0.9.169 package with newer corosync-3.1 and pacemaker-2.1 on RHEL 7.7

by RUGINA Szabolcs-Gavril

Hi folks, Thank you for your time and will to help. We are in the middle of a high pressure because some problems with RHEL HA Cluster/Corosync+Pacemaker/DRBD and we arrived at the point that we upgraded corosync 2.4.3 to 3.1 and pacemaker 1.1.20 to 2.1 but then our setup gives errors with the command "pcs property set no-quorum-policy=stop". The error is: No such file or directory', 'command': '/usr/libexec/pacemaker/pengine metadata' Indeed /usr/libexec/pacemaker/pengine does not exists, I assume it is OK, because in the new pacemaker 3.1 the internal structure was changed.. In the midtime we found out that we could archive the same setting using crm_attribute --name no-quorum-policy -update stop. My questions are: * Is there a reason that pcs has no build for RHEL 7? * Is the crm_attribute the right choice for setting cluster properties and will cover all usecases? * Thank You! BR, Szabolcs
