-lvconvert changes the LV type and includes utilities for LV data
-maintenance. The LV type controls data layout and redundancy.
-The LV type is also called the segment type or segtype.
-
-To display the current LV type, run the command:
-
-.B lvs \-o name,segtype
-.I LV
-
-A command to change the LV type uses the general pattern:
-
-.B lvconvert \-\-type
-.I NewType LV
-
-LVs with the following types can be modified by lvconvert:
-.B striped,
-.B snapshot,
-.B mirror,
-.B raid*,
-.B thin,
-.B cache,
-.B thin\-pool,
-.B cache\-pool.
-
-The
-.B linear
-type is equivalent to the
-.B striped
-type when one stripe exists.
-In that case, the types can sometimes be used interchangably.
-
-In most cases, the
-.B mirror
-type is deprecated and the
-.B raid1
-type should be used.  They are both implementations of mirroring.
-
-The
-.B raid*
-type refers to one of many raid levels, e.g.
-.B raid1,
-.B raid5.
-
-In some cases, an LV is a single device mapper (dm) layer above physical
-devices.  In other cases, hidden LVs (dm devices) are layered between the
-visible LV and physical devices.  LVs in the middle layers are called sub LVs.
-A command run on a visible LV sometimes operates on a sub LV rather than
-the specified LV.  In other cases, a sub LV must be specified directly on
-the command line.
-

-lvcreate creates a new LV in a VG. For standard LVs, this requires
-allocating logical extents from the VG's free physical extents. If there
-is not enough free space, then the VG can be extended (see
-\fBvgextend\fP(8)) with other PVs, or existing LVs can be reduced or
-removed (see \fBlvremove\fP, \fBlvreduce\fP.)
-
-To control which PVs a new LV will use, specify one or more PVs as
-position args at the end of the command line. lvcreate will allocate
-physical extents only from the specified PVs.
-
-lvcreate can also create snapshots of existing LVs, e.g. for backup
-purposes. The data in a new snapshot LV represents the content of the
-original LV from the time the snapshot was created.
-
-RAID LVs can be created by specifying an LV type when creating the LV (see
-\fBlvmraid\fP(7)). Different RAID levels require different numbers of
-unique PVs be available in the VG for allocation.
-
-Thin pools (for thin provisioning) and cache pools (for caching) are
-represented by special LVs with types thin-pool and cache-pool (see
-\fBlvmthin\fP(7) and \fBlvmcache\fP(7)). The pool LVs are not usable as
-standard block devices, but the LV names act references to the pools.
-
-Thin LVs are thinly provisioned from a thin pool, and are created with a
-virtual size rather than a physical size. A cache LV is the combination of
-a standard LV with a cache pool, used to cache active portions of the LV
-to improve performance.

David Teigland	5507307b5f	lvconvert: use command defs for raid/mirror types All lvconvert functionality has been moved out of the previous monolithic lvconvert code, except conversions related to raid/mirror/striped/linear. This switches that remaining code to be based on command defs, and standard process_each_lv arg processing. This final switch results in quite a bit of dead code that is also removed.	2017-02-07 10:38:30 -06:00

David Teigland	09d6229350	lvconvert: add startpoll command using command def This is a new explicit version of 'lvconvert LV' which has been an obscure way of triggering polling to be restarted on an LV that was previously converted.	2017-02-07 10:38:30 -06:00
David Teigland	6312e0872c	lvconvert: snapshot: use command definitions Lift all the snapshot utilities (merge, split, combine) out of the monolithic lvconvert implementation, using the command definitions. The old code associated with these commands is now unused and will be removed separately.	2017-02-07 10:38:30 -06:00
David Teigland	c752f4e1eb	lvconvert: remove unused calls for repair and replace repair and replace are no longer called from the monolithic lvconvert code, so remove the unused code.	2017-02-07 10:38:30 -06:00
David Teigland	cd36b1c698	lvconvert: repair and replace: use command definitions This lifts the lvconvert --repair and --replace commands out of the monolithic lvconvert implementation. The previous calls into repair/replace can no longer be reached and will be removed in a separate commit.	2017-02-07 10:36:18 -06:00
David Teigland	310d9a09fd	lvchange: make use of command definitions Reorganize the lvchange code to take advantage of the command definition, and remove the validation that is done by the command definintion rules.	2017-02-07 10:36:18 -06:00
David Teigland	81e84556b5	process_each_lv: add check_single_lv function The new check_single_lv() function is called prior to the existing process_single_lv(). If the check function returns 0, the LV will not be processed. The check_single_lv function is meant to be a standard method to validate the combination of specific command + specific LV, and decide if the combination is allowed. The check_single function can be used by anything that calls process_each_lv. As commands are migrated to take advantage of command definitions, each command definition gets its own entry point which calls process_each for itself, passing a pair of check_single/process_single functions which can be specific to the narrowly defined command def.	2017-02-07 10:36:18 -06:00
David Teigland	c903d0e4b3	commands: new method for defining commands . Define a prototype for every lvm command. . Match every user command with one definition. . Generate help text and man pages from them. The new file command-lines.in defines a prototype for every unique lvm command. A unique lvm command is a unique combination of: command name + required option args + required positional args. Each of these prototypes also includes the optional option args and optional positional args that the command will accept, a description, and a unique string ID for the definition. Any valid command will match one of the prototypes. Here's an example of the lvresize command definitions from command-lines.in, there are three unique lvresize commands: lvresize --size SizeMB LV OO: --alloc Alloc, --autobackup Bool, --force, --nofsck, --nosync, --noudevsync, --reportformat String, --resizefs, --stripes Number, --stripesize SizeKB, --poolmetadatasize SizeMB OP: PV ... ID: lvresize_by_size DESC: Resize an LV by a specified size. lvresize LV PV ... OO: --alloc Alloc, --autobackup Bool, --force, --nofsck, --nosync, --noudevsync, --reportformat String, --resizefs, --stripes Number, --stripesize SizeKB ID: lvresize_by_pv DESC: Resize an LV by specified PV extents. FLAGS: SECONDARY_SYNTAX lvresize --poolmetadatasize SizeMB LV_thinpool OO: --alloc Alloc, --autobackup Bool, --force, --nofsck, --nosync, --noudevsync, --reportformat String, --stripes Number, --stripesize SizeKB OP: PV ... ID: lvresize_pool_metadata_by_size DESC: Resize a pool metadata SubLV by a specified size. The three commands have separate definitions because they have different required parameters. Required parameters are specified on the first line of the definition. Optional options are listed after OO, and optional positional args are listed after OP. This data is used to generate corresponding command definition structures for lvm in command-lines.h. usage/help output is also auto generated, so it is always in sync with the definitions. Every user-entered command is compared against the set of command structures, and matched with one. An error is reported if an entered command does not have the required parameters for any definition. The closest match is printed as a suggestion, and running lvresize --help will display the usage for each possible lvresize command. The prototype syntax used for help/man output includes required --option and positional args on the first line, and optional --option and positional args enclosed in [ ] on subsequent lines. command_name <required_opt_args> <required_pos_args> [ <optional_opt_args> ] [ <optional_pos_args> ] Command definitions that are not to be advertised/suggested have the flag SECONDARY_SYNTAX. These commands will not be printed in the normal help output. Man page prototypes are also generated from the same original command definitions, and are always in sync with the code and help text. Very early in command execution, a matching command definition is found. lvm then knows the operation being done, and that the provided args conform to the definition. This will allow lots of ad hoc checking/validation to be removed throughout the code. Each command definition can also be routed to a specific function to implement it. The function is associated with an enum value for the command definition (generated from the ID string.) These per-command-definition implementation functions have not yet been created, so all commands currently fall back to the existing per-command-name implementation functions. Using per-command-definition functions will allow lots of code to be removed which tries to figure out what the command is meant to do. This is currently based on ad hoc and complicated option analysis. When using the new functions, what the command is doing is already known from the associated command definition.	2017-02-07 10:36:18 -06:00
