Re: Disk Space Issues
Depends. Best case, you built your system using LVM and have reserved space. You can check this using the df command. If your filesystems start with /dev/mapper, then you are using LVM. You can check for free space using the vgdisplay command (as root): # vgdisplay ...Snip... Alloc PE / Size 96637 / 377.49 GiB Free PE / Size 80065 / 312.75 GiB The free PE/Size line shows you the available space. You could then extend the filesystem that is having issues: # lvextend -L+10G /dev/VG00/foo If you are using standard hard drive partitions (/dev/sda1, /dev/sdb2, etc), then you have to do it the old school way. Using a tool like df, find a directory tree that is large enough that moving it off of the filesystem would make a difference, then copy it to a partition with more space, then symlink it back to its original location. This is an older and uglier way to do it as you could, over time wind up with a bunch of these symlinks all over your hard drive. --b On Mon, May 9, 2011 at 4:23 AM, Daniel Linux darjona.li...@gmail.comwrote: Hi, Can anybody tell me the steps to troubleshoot disk space issues.

Next is take the right action, by emtying / deleting the file, or moving the directory to an new disk. The first step should be to identify all files that are known to compress w/ a decent ratio: 1. Text (logs) 2. HTML 3. etc A/V files typically don't compress well. Many binaries don't compress well. Depending on the primary use of the machine in question it may have a lot of disk space eaten by highly compressible files. If so, compress those files. If the files taking up much of the space are infrequently used, move them to a D2D backup server, CD/DVD, or to tape. If they will never be used again (large temp files) simply delete them. The answer the professor is looking for is not the action you end up taking, but the logic process you use to figure out what you should do--i.e. what steps you take, and how thorough they are, in determining the best course of action. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Hi, Daniel Linux wrote: Can anybody tell me the steps to troubleshoot disk space issues. Depending on the size of the file system to start with, you cold use find as follows to locate larger files for consideration. # find /home -size +10M -ls Generally, larger files once identified can give you a good start.
