Quotas

AFS quotas are handled quite differently from NFS quotas. Under NFS, a given uid is assigned a quota in kilobytes/inodes for a given partition.

In AFS quotas are not done per uid. Instead, they are done on a per volume basis; each volume has a maximum amount of disk space it is allowed to occupy, regardless of which user created the files there.

Volumes are also allowed a soft and hard quota. fs lq on a volume will list it's soft quota; exceeding this by a few k will not instantly cause write() to error out as it would under NFS; the user is allowed approximately 1 MB of grace before the hard quota is enforced and writes will fail. Once a volume is over the soft quota, however, attempting to open and write to new files will fail.
