Hi Guys. I wonder if anybody sees the same or similar issues which I do experience with SST, or maybe could try to reproduce it simply by: [sst] tkey = /etc/my.cnf.d/certs/sst/sst.key tcert = /etc/my.cnf.d/certs/sst/sst.crt Yes, by having SST to use TLS. If I do have those two params in my config then 'galera_new_cluster' fails to bootstrap new cluster. (naturally all other bits to required are set with TLS) Suffices to take those out and cluster bootstrap okey, then, on such up&running cluster, I can on each node put those back in and, one by one, restart the service/server and... it works!? I filled a bug report - https://jira.mariadb.org/browse/MDEV-25435 - and will appreciate if somebody can comment. many thanks, L.
