FreeBSD and high availability services

[David Christensen]

freebsd-questions:

I have a FreeBSD server with a jail providing Samba file sharing 
services for my SOHO LAN:

2020-06-30 18:53:21 toor at samba ~
# freebsd-version
12.1-RELEASE-p5

2020-06-30 18:53:28 toor at samba ~
# uname -a
FreeBSD samba.tracy.holgerdanske.com 12.1-RELEASE-p5 FreeBSD 
12.1-RELEASE-p5 GENERIC  amd64

2020-06-30 19:19:16 toor at samba ~
# pkg info -xI samba
samba410-4.10.13               Free SMB/CIFS and AD/DC server and client 
for Unix


I have another jail that provides CVS services:

2020-06-30 19:18:48 toor at cvs ~
# pkg info -xI cvs
cvs-1.20120905_6               Version control system


The underlying filesystems are ZFS.


I have a second server available and am curious about implementing 
high-availability (HA) for Samba and CVS services.  (I will experiment 
with virtual machines first.)


STFW I see:

Does anyone have any experiences or suggestions with HA services on FreeBSD?
