create_cold_standby issue

jonboy86

Hi all i have 2 vms both running Ubuntu 22.04 with mailcow-dockerized installed on both.
I have ssh keys all setup and working ( no password needed to log in )
i then tried to run create_cold_standby.sh
I have made sure that i have rsync installed on both (v3.2.7)
the script seems to time out at checking rsync version so i disabled the check in the script
i then got [ERR] - Could not prepare remote for mailcow base directory transfer
I am stuck and have to migrate our company emails ASAP as our ISP is stopping hosting( PIA)

My 2 servers are on different ranges but connected via a site to site vpn no firewals between

got a bit further now gets stuck creating remote mount points
but did 2 volumes then crashed out

What happens if you just ssh between the servers?

Have you tried to just rsync’ing random folder across manually?

Hi Lnxgeek,

That all seems to work fine .
I dont need a keyfile to log into the second from the master .

sort of worked but now getting this

SOLVED
Looks like it was the site-site vpn encapsulation that was messing up the ssh packets. did a direct and worked like a charm.
