GENERAL OPTIONS¶

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.

INHERITANCE¶

When new object is created in MooseFS, attributes such as storage class, trash retention and extra attributes are inherited from parent directory. So if you set i.e. "noowner" attribute and storage class to "important" in a directory then every new object created in this directory will have storage class set to "important" and "noowner" flag set. A newly created object inherits always the current set of its parent's attributes. Changing a directory attribute does not affect its already created children. To change an attribute for a directory and all of its children use -r option.

PATTERNS¶

Since version 4.2.0 above attributes (storage class, trash retention and extra attributes) can be overridden by defining specific name patterns.
