Your files are stored on one of central disk servers and are available on all Unix workstations at the IMA. We do not currently enforce strict disk quotas for our visitors; however, be aware that you are sharing space on a disk partition with many other users. Please do not use so much space in your home directory that other users can't get enough storage to do their work. We may occasionally ask users to remove files from the system that are no longer needed to make room for new files.
If you are working with or generating large amounts of data, temporary ``scratch'' space is available on many machines in /scratch. /scratch, if present, is on a local disk that is not shared with other workstations, but which is faster than your home directory. Files in ``scratch'' space are not backed up to tape. As many of our workstations do not allow ftp access, you may find it easier to use scp to transfer files in and out of local /scratch directories; see section 10.1 for details.
The command df -k will show you how much space is currently available on mounted disk partitions. If you give a directory as an argument (df -k /scratch), it will show how much space is free in that directory's disk partition. The command du -k will show you how much space the current directory is using; you must have read access to all subdirectories of the current directory to get accurate results.
