I'm currently faced with a challenge.<br>
<br>
What we have:<br>
<blockquote>A 2-Node DRBD setup:<br>
<blockquote>ClientA is the primary node and is located offsite<br>
ClientB is onsite<br>
Approximately 1.5 TB of data is currently replicated using
protocol A w/ ahead/behind enabled<br>
Data changes about 30GB per month<br>
</blockquote>
</blockquote>
<br>
Due to a unique set of requirements we need to add 2 nodes that are
relatively onsite.<br>
<br>
The primary offsite server is replicated over a slow WAN connection
with monthly data transfer limits.<br>
<br>
As such we need to replicate the data from ClientB to the 2 new
servers ending up in a 4-node cluster.<br>
<br>
Our initial replication between ClientA and ClientB was via truck,
this however is not an option for the 2 new servers.<br>
<br>
I'm looking for recommendations to migrate from this 2-node setup to
a 4-node configuration without having to pull all 1.5TB over the WAN
link<br>
<br>
Thanks,<br>
