Assuming you are running under z/VM: If you have all file systems on the same disk you may want to move one or more directories to their own physical disk. You can use the command du -sk * to get the current size of the files in a directory and its subdirectories. Create a disk of a size that includes room for files and growth, copy the files from the directory to the new disk, mount the new disk at that directory, and erase the old files. (You may need to perform the erasure from another Linux instance. See below.) Modify /etc/fstab so the new disk gets automatically mounted. Directories that are most often split off are /tmp, /usr, /var, and /home. The idea is to keep those file systems that most often fill up from affecting the root ( / ) file system.
After you mount the new file system you will not have any extra free space. The old files are still under the mounted file system taking up space. Shut down the problem operating system. Detach the problem disk (or log off). From another Linux instance link to that disk. Mount it at /mnt. Erase all the files and subdirectories under /mnt/var/. Umount the disk and detach it. Log on to the problem system and boot. Your world should be bright and sunny! Some file systems cannot be split from root ( / ). They are needed before the other file systems get mounted. An example is /etc. If this all seems overwhelming, you can just DDR your current disk to a bigger disk, swap the disk virtual addresses, and boot from the new disk. There is a resize2fs command so that will expand the file system so it can use the new space. Others who know more can expand on these notes.
