PARTED Questions in Red Hat, post-installation
I am fairly new to Linux and it would seem that I have made a boo-boo. I have a network of MS Windows XP and 2000 machines, and the server is a RH 8.0 Pro box. This server runs my sendmail, DNS, Samba, etc. A few days ago, in the MS Outlook clients for e-mail, I started getting messages saying:
Task 'goliath - Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 452 4.4.5 Insufficient disk space; try again later'
Goliath is the hostname of the RH server. Now, it turns out that I have indeed run out of space (as you will see). I deleted some logs to gain back some space on a temporary solution, but I need a more permanent one. "df -h" gives me this output:
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 4.8G 4.6G 1.4M 100% /
/dev/hda3 107G 21G 80G 21% /home
none 377M 0 376M 0% /dev/shm
Unfortunately, when I installed Linux, you can see that I only made 2 mount points, / and /home. I believe that what I need to do is shrink down the /home partition by 20G and create 2 new mounted partitions, /var and /etc. I would like /var to be 15GB and /etc to be 5GB. Should I also create a /boot partition of 100MB or so? Now, like I said, this is a server, so this needs to be done without harming it at all! From what I have heard, I can do all of this with a command called "parted" if I reboot the server with install CD 1. I have never even used parted, and I certainly do not know how to use it. I have rebooted the server and gotten to the parted command, but once I got there, I became overwhelmed. That is why I am writing for your help now.
Please, is there anyone who could walk me through this like I am a five year old? Like I said, I am fairly new to Linux and am learning as I go, but the biggest problem is that if something goes wrong with the server, I lose internet and e-mail access, and that is not good. I need this to go smoothly, and I am more than willing to put aside any pride and let the masters help me. The one problem you should all know is that I do NOT have a working tape backup (or any means of backup) yet. I have a DLT drive coming, but it is not here yet, so I cannot afford to screw up the system with parted. Can anyone please help me out? I would be most grateful! Thank you in advance.
