Chapter 7: The AFS File System
UNIX divides disks into partitions. AFS further divides partitions into subsections called volumes. A volume houses a subtree of related files and directories. Normally, volumes are considerably smaller than traditional file systems. For example, each user's home directory would normally be stored in a separate volume. Large sub-directories are further sub-divided. You do not need to know which file server houses any volume. AFS locates volumes automatically.
To examine the quota on a volume within AFS, the fs listquota command may be used. You can request information on several directories at a time. For example the following command requests information on the current working directory (.) and on another one specified via an environment variable (see section 9.1):
% fs listquota . $UAFWWW Volume Name Quota Used % Used Partition room.aheavey 130000 126024 97%<< 75% <<WARNING files.reports.UNIX 2000000 77370 4% 63%
The output includes the name of the volume containing the specified directory(ies), the quota size, amount used, percent used, and the percent of space used on the partition containing the volume. You might also get a warning! All sizes are in kilobytes.
