Hello,


We're running RedHat 7.2 on a basic webserver and for some reason, our top level mount point has filled up for reasons unknown. df -h shows me this:

Filesystem Size Used Avail Use% Mounted on
/dev/hda7 486M 487M 0 100% /
/dev/hda1 45M 6.0M 37M 14% /boot
/dev/hda8 20G 3.1G 16G 17% /home
none 250M 0 249M 0% /dev/shm
/dev/hda6 486M 8.1M 453M 2% /tmp
/dev/hda2 4.8G 1.4G 3.2G 29% /usr
/dev/hda5 486M 51M 410M 11% /var

I'm still quite the Linux newbie and I'm not sure what I can do to dig through all these directories and clear out some space. Does anyone have any likely guesses as to what's filled things up? Main applications running on the server are Apache, mySQL, ColdFusion... thanks to anyone who can help.

hmmm, is there anything installed under /root? it seems your partition scheme is about right you have separate partitions for /home, /usr, /tmp and /var. Is there a /opt directory, some programs tend to get installed there, some users tend to use it for optional software (opt - is for optional), if you do
du /root
what do you get?

Well I du'ed /root and it appears there's only about 1 MB of files in there. ColdFusion was installed in the /opt directory (was aware of this) and it occupies about 58 MB, which is significant. I totalled together all the directories except for boot, home, mnt, tmp, usr, and var and got something like 121 MB which should be well below the alotted 486 MB for the "/" mount. Here's my only question - I neglected /mnt because I figured that any network mounts I do won't count against my disk space - will they? I mounted shares from a Mac OS X server in our office using smbmount to different folders I created in the /mnt directory - could this be taking up my disk space somehow? Otherwise, I'd be totally baffled to know wherethe other 350 MB are disappearing to. Any more help you could give would be greatly appreciated - thanks!

Hey, thanks a lot for your help - I discovered what the problem was. I had some automated backup scripts running each night that tar'd and gzip'd our entire webroot and then copied them to that OS X server, which is backup up via tape. Apparently, someone rebooted the machine after it had been up for 90 days and failed to remount the network drives, so the files were actually being written to my hard disk. Sorry to waste your time with such a trivial question, but thanks very much for your help!

No problem
