Re: [cobalt-users] Disks when upgrading xtr to 550

[josh <josh@xxxxxxxxxxxxxxxxxx>]

I hope you get this - I've been using a RaQ 3i as a temporary server
-- but I wound up not testing thoroughly enough and tried to upgrade
too soon.

I though about it -- but I realized that the only things that I use
the server for are 1. web server 2. mail server 3. mysql database
server. 4. squid proxy and whatever I gain in redundancy I wind up
losing from adding overhead to the proxy.

Guess I'll go for it -- let me know if you get this even if you've
nothing to add.
