High Availability and disk space

The freePBX wiki says HA requires 250GB of disk space.
Now before I put HA on my production servers, I want to test it on two servers that have only 160GB hard drives.
You think that might impact my test or not work at all?

It will not work; the distro installer specifies that a hard drive (or RAID array) needs to have at least 250GB before it will allow you to continue.

Thanks ds_scalar.
Are you sure?
Installing the distro has worked and FreePBX is running even though it is 160GB.
Just wondering if that is gonna bite me later.

It depends on how large your database, sound files, MoH etc. are. Just make sure you are careful to watch your available disk space since you need to accommodate replication of /drbd
