These tools are used to check, define and delete quotas. Quota is set on a
directory. It can be set in one of 4 ways: for number of inodes inside the
directory (total sum of the subtree's inodes) with -i
options, for sum of (logical) file lengths with -l
for sum of chunk sizes (not considering goals) with -s
options and for physical hdd space (more or less chunk sizes multiplied by
goal of each chunk) with -r
options. Small letters set soft
quota, capital letters set hard quota. -a
mean all kinds of quota. Quota behaviour is described
below. For soft quota grace period can be defined using -p
grace period is not given then default value will be used (option defined in
mfsmaster.cfg or seven days if it's not defined there).
Quota is always set on a directory. Hard quota cannot be exceeded anytime. Soft
quota can be exceeded for a specified period of time. Once a quota is exceeded
in a directory, user must go below the quota during the grace period. If not,
the soft quota for this particular directory starts to behave like a hard

options to select format of printed numbers. -n
causes to print exact numbers, -h
uses binary prefixes (Ki, Mi, Gi as
2^10, 2^20 etc.) while -H
uses SI prefixes (k, M, G as 10^3, 10^6
show plain numbers respectivaly in
kibis (binary kilo - 1024), mebis (binary mega - 1024^2) and gibis (binary
giga - 1024^3). The same can be achieved by setting MFSHRFORMAT
environment variable to: 0
(exact numbers), 1
(binary prefixes), 2
(SI prefixes), 3
(exact numbers and binary prefixes), 4
(exact numbers and
SI prefixes). The default is to print just exact numbers.
