I have started upgrading our systems to RHEL 8.5 (actually AlmaLinux 8.5), which was just recently released. After the upgrade, the nodes cannot rejoin the cluster. I spent about an hour searching on log entries until I found the issue below. [[PXC-3679] SST fails after the update of socat to ‘1.7.4.0’ - Percona JIRA](https://jira.percona.com/browse/PXC-3679) Apparently the fix is due in XtraDB 8.0.25, which has not yet been released. So, your choices are a) do not upgrade to RHEL 8.5 until the new version or a fix for XtraDB has been released or b) manually patch/edit the /usr/bin/wsrep\_sst\_xtrabackup-v2 file with the following changes. [https://github.com/percona/percona-xtradb-cluster/pull/1440/commits/7452bbbac40fdceca07a0801aafac61cb6faa75c](https://github.com/percona/percona-xtradb-cluster/pull/1440/commits/7452bbbac40fdceca07a0801aafac61cb6faa75c)) Hope this saves someone else some time. Wish I had known before I upgraded. Jim L ---
