Fixed In Version: ceph-16.2.7-115.el8cp
Doc Type: Bug Fix
Doc Text:
.MDS daemons no longer crash when receiving metrics from new clients Previously, in certain scenarios, newer clients were being used for old CephFS clusters. While upgrading old CephFS, `cephadm` or `mgr` used newer clients to perform checks, tests or configurations with an old Ceph cluster. Due to this, the MDS daemons crashed when receiving unknown metrics from newer clients. With this fix, the `libceph` clients send only those metrics that are supported by MDS daemons to MDS as default. An additional option to force enable all the metrics when users think it's safe is also added.
