These days --partial is only used with activation in lvchange/vgchange. It probably had another meaning at some point in history which is no longer used, so ignore it in those cases. When included in the OO list, the option is advertised in help/man output, implying it is meaningful to the command, when in fact the command never uses it. The IO list means the option won't cause an error if it's used, but is not displayed as an valid option for the command. If the option is not included in either OO or IO lists, using the option would cause a command error, which would cause problems for anyone is using the option for historical reasons.

# 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.
|
|
#
|
|
# lvcreate generally requires a VG arg in position 1 and does not
|
|
# require the --name option (when --name is omitted, a name is
|
|
# generated). But, all commands of that form have a variant which
|
|
# is not defined here, but which is automatically recognized as
|
|
# being equivalent. That variant allows the required VG arg to
|
|
# be omitted when --name VG/LV is specified, or when the
|
|
# LVM_VG_NAME env var is set and --name LV is specified.
|
|
# The lvcreate variants with --name and without a VG arg are
|
|
# automatically recognized as an alternative to the defined
|
|
# command forms requiring the VG and no --name.
|
|
# Also, --thinpool VG/LV or --cachepool VG/LV can be used in
|
|
# place of --name to provide the VG name instead of pos 1.
|
|
#
|
|
# Note that one the most difficult aspect of these definitions is
|
|
# the variants of --thin / --type thin / --type thin-pool,
|
|
# --cache / --type cache / --type cache-pool.
|
|
# There are no consistent rules to follow and the behaviors are
|
|
# unpredictable; each possible variation and combination needs
|
|
# to be tested individually to see what it means.
|
|
#
|
|
# 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.
