I am trying to mirror a Centos OS colo server I have. I just recently rented a temp box from my data center to start this project off a bit.
Here is the problem I am running into.
I am trying to use heartbeat and DRBD on both servers to do this unless someone here can provide me a better solution.
>>We will need a fresh partition on each servers so that we can create a DRBD between both the servers on that partition. As we cannot create a DRBD on a live partition as >>it will reinitialize it and will loose the data subsequently
>>Heartbeat can be set up without much prerequisite
>>We will need an external floating IP to be set up by the DC(working by the routers) so that we can assign them to the active server as per need
>>We will need to create internal floating IPs as well, which can be done by us(we will just need an internal IP assigned as well)
Apparently my DC can't provide me with a floating ip.
How can I setup the mirroring. Even if I had two servers in different locations how can I set this up
You can install and run DRBD without a floating IP.
The floating is used to have an automatic failover mechanism.
What are you looking for exactly? Is it just a mirror or an hot standy you are trying
