HDD Partitioning With 2 HDDs + CentOS V. Select
Aug 17, 2008I have 2 questions:
1) I have one 80Gb HDD and one 250Gb HDD ( all are s-ata ).
In which practical way they should be partitioned? I thought to setup OS on 80Gb HDD and /home on 250Gb HDD.
2) Which version of CentOS is currently the most stable for cPanel? I had an experince with CentOS 5, there were various problems with mail and mysql.. And now I want to install CentOS 4.6.
The server will have CentOS and cPanel installed.

Backup My Remote Dedicated Server With Centos Installed Over Ssh

Installed TightVNC. Fails. Can't Find Fonts When Ran. Running CentOS.
Aug 13, 2007I'm trying to run freenx and tightvnc. I can't get freenx working, so I moved on to try to install tightvnc. I installed the Fedora rpm on my CentOs box. Everything installed.
When I tried to run it, it failed and exited. It says I'm missing fonts. I had the technicians install GNOME when it was being installed, but I don't think its configured.

Why Are Hdds Such Low Space On Dedicated Servers
Nov 29, 2008With 1.5TB drives out now and 500GB and 1TB being dirt cheap, I still see that 80-120GB is standard on dedicated servers. If you want a 500Gig you will pay up the ***. Why is this? It's actually EASIER to buy a 500GB drive then a 120GB one nowdays.
I'm guessing it's because they still have tons of the lower space ones on site so it stops them from needing to buy new ones.

Host Ability To Self Detect
Nov 13, 2008Do web hosts have the means to self-detect or self-correct problems with people's websites? If so, is there a name for this ability?
Seems that every host I've used has to be *told* about major problems, such as the server or database being down completely. I'm tired of going out of town fearing a site crash. I don't expect them to catch every problem, but when the failure is so blatant, it would be nice if they caught it...
How would I find a host who does this?
