$HOME - Home file system

Each user as their own home directory which is stored on the HOME file system.  The amount of space available for a given account is restricted via quotas.  The number of files is not restricted, however.

There are two kinds of quota limits: soft and hard.  The soft limit means that one can still write files to the file system however one should reduce the amount of used space by compressing and/or deleting files.  The hard limit is a limit one cannot go over.  If one exceeds the hard limit it is no longer possible to write files to the filesystem without first deleting files and thereby reducing one's usage to below the hard limit.

To see how much disk space one is currently using on the file system and to see what one's quota is one need only use the quota command.
