Thanks. Both FreeBSD 13.5 & 14.3 are "current", just from different major ! branches. I wonder why they use such different locale/collate versioning, ! meaning that they differ roughly by that much as in 34 vs. 43. Maybe someone ! there mistyped 34?)
Hi, I ran into that same (surprizing) error when upgrading FreeBSD 13.x to 14.x. In FreeBSD the major version switches are for exactly that purpose: to change interfaces or libaries that may induce incompatibilities The version numbers (34.0 vs 43.0) might mean anything, I don't know; but they originate from these places in the OS distribution: $ hd /usr/share/locale/en_US.UTF-8/LC_COLLATE | head -1 00000000 42 53 44 20 31 2e 30 0a 00 00 00 00 34 33 2e 30 |BSD 1.0.....43.0| In Yor case, apparently the conclusion is that you need the same FreeBSD major version throughout Your replication set. -- PMc
