I have installed and configured DRBD on my Ubuntu 9.10 Servers, by following the links below.
link text1 and link text2
I'm in a plan to configure Ubuntu Servers for High Availability, so i have tested DRBD working and it's fine as per the links i referred. But my major requirement is I could get other server into production if the main server gets down/corrupted. Is it possible to configure DRBD so that any changes made on primary server to '/'
are replicated to secondary server?.
EDIT:
Dear Experts:
I have a Ubuntu server which hosts apache, tomcat, mysql, ldap and so on. I don't know how to say... like if this server gets corrupted or malfunctions I should immediately get another system with same databases applications, services, files and directories (just like a clone) into working. I wondering if there is something like primary and secondary which replicate (entire system) each other and if in case the primary server fails I can immediately come up with the secondary.
I'm not only talking about DRBD it might be any third party tool that meets my entire requirement. I have to do this by the time assigned to me. Somehow you try to understand what I'm in need of and put an end to this
Thank you!
