NAME
mfstrashtime - MooseFS trash time (retention) management tools
SYNOPSIS
mfsgettrashtime [-r] [-n|-h|-H|-k|-m|-g] OBJECT...
mfssettrashtime [-r] [-n|-h|-H|-k|-m|-g] SECONDS[+|-] OBJECT...
mfscopytrashtime [-r] [-n|-h|-H|-k|-m|-g] SOURCE_OBJECT OBJECT...
mfsrgettrashtime [-n|-h|-H|-k|-m|-g] OBJECT...
mfsrsettrashtime [-n|-h|-H|-k|-m|-g] SECONDS[+|-] OBJECT...
DESCRIPTION
These tools operate on object's trashtime value, i.e. the number of seconds the file is preserved in
special trash directory before it's finally removed from filesystem. Trashtime must be non-negative
integer value.
mfsgettrashtime prints current trashtime value of given object(s). -r option enables recursive mode,
which works as usual for every given file, but for every given directory additionally prints current
trashtime value of all contained objects (files and directories).
mfssettrashtime changes current trashtime value of given object(s). If new value is specified in
SECONDS+ form, trashtime value is increased to SECONDS for objects with lower trashtime value and
unchanged for the rest. Similarly, if new value is specified as SECONDS-, trashtime value is decreased to
SECONDS for objects with higher trashtime value and unchanged for the rest. -r option enables recursive
mode. These tools can be used on any file, directory or deleted (trash) file.
mfscopytrashtime tool can be used to copy trashtime value from one object to another.
mfsrgettrashtime and mfsrsettrashtime are deprecated aliases for mfsgettrashtime -r and mfssettrashtime
-r respectively.
PRECISION
Since version 3.0 of MooseFS trashtime is stored in the system as number of hours the file is preserved
in trash directory. Given value in seconds is rounded up to hours.
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, 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.
