Only a command that conforms to one of the specifications will be processed. (LV type conformance is checked after vg_read and before single_fn processing.)

# Syntax
|
|
#
|
|
# A new command has a unique combination of:
|
|
# command name, required option args and required
|
|
# positional args.
|
|
#
|
|
# To define a new command, begin a single line with a
|
|
# command name, followed by required options/args,
|
|
# (e.g. --foo, or --foo val), followed by required
|
|
# positional args, (e.g. VG)
|
|
#
|
|
# After the single line of required elements are lines
|
|
# of optional elements:
|
|
# OO: <optional --option args>
|
|
# OP: <optional positional args>
|
|
#
|
|
# command_name required_opt_arg ... required_pos_arg ...
|
|
# OO: optional_opt_arg, ...
|
|
# OP: optional_pos_arg ...
|
|
#
|
|
# required_opt_arg/optional_opt_arg must begin with the
|
|
# long form option name, e.g. --foo. If the option name
|
|
# takes a value, then the type of value is specified,
|
|
# e.g. --foo String.
|
|
#
|
|
# Possible option names are listed in args.h
|
|
#
|
|
# Use --foo_long to specify that only the long form of
|
|
# --foo is accepted by the command. (This is uncommon.)
|
|
#
|
|
# Possible option arg types are shown in tools/vals.h,
|
|
# e.g. Bool, String, VG, SizeMB.
|
|
#
|
|
# --option args outside the list of types in vals.h are treated
|
|
# as literal (non-variable) strings or numbers.
|
|
#
|
|
# positional args can be multiple types separated by |, e.g. VG|LV|Tag
|
|
#
|
|
# If a positional arg is repeatable, it is followed by ..., e.g. VG|LV|Tag ...
|
|
#
|
|
# LV can have a suffix indicating the LV type, e.g. LV_linear, LV_thinpool.
|
|
# LV_raid represents any raidN. LV_type1_type2_type3 when the LV is
|
|
# limited to multiple specific types.
|
|
#
|
|
# Note that two commands whose required paramters differ only by
|
|
# the LV types they accept are ambiguous. That is, they cannot be
|
|
# distinguished by just looking at the command, but require reading
|
|
# the VG to find the LV type. So, command definitions that differ
|
|
# only in accepted LV types are not allowed. It would be best to
|
|
# distinguish them by using different option names.
|
|
# There are FIXME's below for some of these cases.
|
|
#
|
|
# VG, LV can have the suffix _new, indicating the named VG or LV
|
|
# does not yet exist.
|
|
#
|
|
# If Select is included in pos_arg, it means that the pos_arg
|
|
# may be empty if the --select option is used.
|
|
#
|
|
# --size and --extents are interchangable, but only --size is used
|
|
# in these definitions to keep them simpler. --extents is
|
|
# automatically included and recognized as an alternative to --size.
|
|
#
|
|
# Some options have multiple names, but only one form of the name
|
|
# is used in these definitions. Synonyms will be recognized when
|
|
# matching a command to a command definition.

|
|
# Including OO_NAME after a command name on the required line

# means that any one of the options is required and the rest
|
|
# are optional. The usage syntax for this case is printed as:
|
|
# command (--foo A, --bar B)
|
|
#
|
|
|
|
#
