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, trashtime 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.
