Managing GPFS quotas
The GPFS quota system helps you to control the allocation of files and data blocks in a file system.
GPFS quotas can be defined
for:
- Individual users
- Groups of users
- Individual filesets
Quotas are enabled by the system administrator when control over the amount of space used by the
individual users, groups of users, or individual filesets is required. By default, user and group
quota limits are enforced across the entire file system. Optionally, the scope of quota enforcement
can be limited to an individual fileset boundary.
Note: A large number of quota records per file
system can result from the following scenarios:
- There are a very large number of users, groups, or filesets.
- If the --perfileset-quota option is enabled, the number of possible quota records is the number of filesets times number of users (and groups).
