Hello all, I have a couple problems with two Centos installs. One is my Dedicated hosting plan. I have been trying very hard to build some strong skills in system administration because the task apparently is more complex than I imagined... or it appeared that way to a web developer, who reported he was not a system admin and so even though he could do quite a bit on the server - more than I could at the time - he felt my task of needing to fix a partitioning problem on my systems needed to be referred to a system administrator ( a role I'm trying to take on). On my dedicated server, I have had a couple partitions that are quite often full and one of them tends to fill up very quickly now. The other partition, I believe the /var partition seems ok now that I have moved most of my accounts elsewhere. I believe the databases were there and so by moving accounts elsewhere, much space was freed up. Not it is the /etc partition that is full every other day. It is a 10GB partition and most of the data is in the mail spool directories. I don't have many accounts, so I'm not sure how to fix the issue. I get thousands of spam messages and yet, I just realized, they don't seem to be going to the email addresses I have on that particular dedicated server - or the domains hosted there. All manner of problems develop when this happens. So, this is on a 500GB disk with a good bit of free space, such as in the home partitions. My domains are setup like this: /home/username/public_html. So, If I setup the domain mydomain.com, I'd use a username of mydom. Anyway, this partition has available space on it. How can I (maybe?) shrink one partition, moving files as necessary, and then increase the storage size for the 10GB partitions, /etc and /var? Can this be done without breaking things? Second issue... My business/development server... Centos 6.4. I cannot boot into it now because the /tmp partition is full. Most of the fixes I found online involve what you do once you boot into it. Initially I was getting an error about Power Management and googling this turned up info. Saying that a disk partition is full. Indeed, checking the boot log, that was the case. It could not create files in the /tmp partition/directory - no more space. So, I was trying to get to a place where I could delete some tmp files as a first step. Since I cannot boot up, and didn't know what to do from grub to address the issue, I tried booting to live CD. The files are locked, of course, and/or protected, or I don't have permission to delete anything. Is there any way to from adjust the size of the different partitions, shrink some space in one partition and expand it/reclaim it elsewhere, e.g. the /etc partition? Again, I cannot boot to the desktop. I got as far as the grub boot loader and didn't find anything that would let me adjust partitions.
Thanks in advance for any help, Bruce
