Yes I am using it on front ends for the website that runs dynamic contents.
There are 2 main content servers running hearbeat .
They also act as the main mail, ldap and mysql servers.
The are sharing a scsi raid consitsing two logical volumes.
a 56 GB volume (for mail, ldap, etc)
and a 9 gb volume (for web contents)
There are 6 frontend servers that are running apache, php3 modperl etc.
each with 2 9 gb disk.
the first 9gb disk is for system (/boot, / etc)
the second 9gb disk is /www this disk is running software raid 1
with the nbd that is mounted from the main file servers.
The load balancing of the frontend nodes is done with Cisco Localdirector (I
didnt use LinuxVirtualServer cause the hardware already existed)
I will be rolling out the site in a week.
It is the first time that I have played with this nbd thing. So I am putting my
neck on line :) I hope it performs well.
thnx
