mfsquota - MooseFS quota management tools

mfsgetquota [ -n|-h|-H|-k|-m|-g] DIRECTORY...
mfssetquota [ -n|-h|-H|-k|-m|-g] [ -p grace_period] [ -i|-I inodes] [ -l|-L length] [-s|-S size] [-r| -R realsize] DIRECTORY...
mfsdelquota [ -a|-A|-i|-I|-l|-L| -s|-S| -r|-R] [ -n|-h|-H|-k| -m|-g] -f DIRECTORY...
mfscopyquota [ -n|-h|-H|-k|-m|-g] SOURCE_DIRECTORY DESTINATION_DIRECTORY

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, -I options, for sum of (logical) file lengths with -l, -L options, for sum of chunk sizes (not considering goals) with -s, -S options and for physical hdd space (more or less chunk sizes multiplied by goal of each chunk) with -r, -R options. Small letters set soft quota, capital letters set hard quota. -a and -A options in mfsdelquota mean all kinds of quota. Quota behaviour is described below. For soft quota grace period can be defined using -p option. When 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 quota.

Most of mfstools use -n, -h, -H, -k, -m and -g 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 etc.). -k, -m and -g 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 or h (binary prefixes), 2 or H (SI prefixes), 3 or h+ (exact numbers and binary prefixes), 4 or H+ (exact numbers and SI prefixes). The default is to print just exact numbers.
