438e0050df config: add silent mode
Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.

When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]

Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.

6e55201144 args: increase major:minor limit to 4095:1048575
Remove the limit for major and minor number arguments used while specifying
persistent numbers via -My --major <major> --minor <minor> option which
was set to 255 before. Follow the kernel limit instead which is 12 bits
for major and 20 bits for minor number (kernel >= 2.6 and LVM formats
that does not have FMT_RESTRICTED_LVIDS - so still keep the old limit
of 255 for lvm1 format).

2729720fd3 args: add --activate synonym for --available arg
We're refererring to 'activation' all over the code and we're talking
about 'LVs being activated' all the time so let's use 'activation/activate'
everywhere for clarity and consistency (still providing the old
'available' keyword as a synonym for backward compatibility with
existing environments).

0c506d9a40 Support the ability to replace specific devices in a RAID array.
RAID is not like traditional LVM mirroring.  LVM mirroring required failed
devices to be removed or the logical volume would simply hang.  RAID arrays can
keep on running with failed devices.  In fact, for RAID types other than RAID1,
removing a device would mean substituting an error target or converting to a
lower level RAID (e.g. RAID6 -> RAID5, or RAID4/5 to RAID0).  Therefore, rather
than removing a failed device unconditionally and potentially allocating a
replacement, RAID allows the user to "replace" a device with a new one.  This
approach is a 1-step solution vs the current 2-step solution.

example> lvconvert --replace <dev_to_remove> vg/lv [possible_replacement_PVs]

'--replace' can be specified more than once.

example> lvconvert --replace /dev/sdb1 --replace /dev/sdc1 vg/lv

6d04311efa Add the ability to split an image from the mirror and track changes.
~> lvconvert --splitmirrors 1 --trackchanges vg/lv
The '--trackchanges' option allows a user the ability to use an image of
a RAID1 array for the purposes of temporary read-only access.  The image
can be merged back into the array at a later time and only the blocks that
have changed in the array since the split will be resync'ed.  This
operation can be thought of as a partial split.  The image is never completely
extracted from the array, in that the array reserves the position the device
occupied and tracks the differences between the array and the split image via
a bitmap.  The image itself is rendered read-only and the name (<LV>_rimage_*)
cannot be changed.  The user can complete the split (permanently splitting the
image from the array) by re-issuing the 'lvconvert' command without the
'--trackchanges' argument and specifying the '--name' argument.
	~> lvconvert --splitmirrors 1 --name my_split vg/lv
Merging the tracked image back into the array is done with the '--merge'
option (included in a follow-on patch).
	~> lvconvert --merge vg/lv_rimage_<n>

The internal mechanics of this are relatively simple.  The 'raid' device-
mapper target allows for the specification of an empty slot in an array
via '- -'.  This is what will be used if a partial activation of an array
is ever required.  (It would also be possible to use 'error' targets in
place of the '- -'.)  If a RAID image is found to be both read-only and
visible, then it is considered separate from the array and '- -' is used
to hold it's position in the array.  So, all that needs to be done to
temporarily split an image from the array /and/ cause the kernel target's
bitmap to track (aka "mark") changes made is to make the specified image
visible and read-only.  To merge the device back into the array, the image
needs to be returned to the read/write state of the top-level LV and made
invisible.

77d308ef77 Fix --[vg]metadatacopies arg processing 2010-06-30 20:21:03 +00:00
Dave Wysochanski
a9d8bf269a Allow 'all' and 'unmanaged' values for --vgmetadatacopies.
Allowing an 'all' and 'unmanaged' value is more intuitive, and
provides a simple way for users to get back to original LVM behavior
of metadata written to all PVs in the volume group.

If the user requests "--vgmetadatacopies unmanaged", this instructs
LVM not to manage the ignore bits to achieve a specific number of
metadata copies in the volume group.  The user is free to use
"pvchange --metadataignore" to control the mdas on a per-PV basis.
If the user requests "--vgmetadatacopies all", this instructs LVM
to do 2 things: 1) clear all ignore bits, and 2) set the "unmanaged"
policy going forward.

Internally, we use the special MAX_UINT32 value to indicate 'all'.
This 'just' works since it's the largest value possible for the
field and so all 'ignore' bits on all mdas in the VG will get
cleared inside _vg_metadata_balance().  However, after we've
called the _vg_metadata_balance function, we check for the special
'all' value, and if set, we write the "unmanaged" value into the
metadata.  As such, the 'all' value is never written to disk.

72e0743621 This patch adds the capability to split off a mirror legs.
It is pretty much the same as reducing the number of
mirror legs, but we just don't delete them afterwards.

The following command line interface is enforced:
  prompt> lvconvert --splitmirror <n> -n <name> <VG>/<LV>
where 'n' is the number of images to split off, and
where 'name' is the name of the newly split off logical volume.

If more than one leg is split off, a new mirror will be the
result.  The newly split off mirror will have a 'core' log.
Example:
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
  LV            Copy%  Devices
  lv            100.00 lv_mimage_0(0),lv_mimage_1(0),lv_mimage_2(0),lv_mimage_3(0)
  [lv_mimage_0]        /dev/sdb1(0)
  [lv_mimage_1]        /dev/sdc1(0)
  [lv_mimage_2]        /dev/sdd1(0)
  [lv_mimage_3]        /dev/sde1(0)
  [lv_mlog]            /dev/sdi1(0)
[root@bp-01 LVM2]# lvconvert --splitmirrors 2 --name split vg/lv /dev/sd[ce]1
  Logical volume lv converted.
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
  LV               Copy%  Devices
  lv               100.00 lv_mimage_0(0),lv_mimage_2(0)
  [lv_mimage_0]           /dev/sdb1(0)
  [lv_mimage_2]           /dev/sdd1(0)
  [lv_mlog]               /dev/sdi1(0)
  split            100.00 split_mimage_0(0),split_mimage_1(0)
  [split_mimage_0]        /dev/sde1(0)
  [split_mimage_1]        /dev/sdc1(0)

It can be seen that '--splitmirror <n>' is exactly the same
as '--mirrors -<n>' (note the minus sign), except there is the
additional notion to keep the image being detached from the
mirror instead of just throwing it away.

7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'

0ddb66efba Add --pvmetadatacopies as a synonym for --metadatacopies in various commands.
Going forward, we would like to allow users to specify the total
number of metadatacopies in a VG rather than on a per-PV basis.  In
order to facilitate that, introduce --pvmetadatacopes to replace
--metadatacopies everywhere.  We still allow --metadatacopies for
pv commands, but require --pvmetadatacopies for vg commands.
Eventually we will introduce --vgmetadatacopies.  Once we do that,
we should either deprecate --metadatacopies or make it a synonym based
on the command (pvmetadatacopies for pv commands, and vgmetadatacopies
for vg commands).  The latter option would likely just require a simple
'strncpy' check against cmd->command->name to qualify the merge_synonym
call.

Update nightly tests to cover the pvmetadatacopies synonym.

Note that this patch is the result of an eariler review comment for
the implicit pvcreate patches.  Should apply cleanly on top of the
implicit pvcreate patches (I applied after patch 10/10 in that series).

NOTE: This patch will require --pvmetadatacopies for vgconvert as
--metadatacopies is no longer accepted.

8929ce6651 Add --dataalignment to pvcreate to specify alignment of data area. (mbroz)
This patch is not fully tested and leaves some related bugs unfixed.

Intended behaviour of the code now:

  pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.

  In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.

  Currently, the field storing the size of the data area in the PV label
header always holds 0.  As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).

Jonathan Earl Brassow
19583d115c This patch changes the arguments that specify the mirror
log type.  Previously, we had a '--corelog' argument that
would change the default type from 'disk' to 'core'.  I
think that creates too much confusion - especially when
doing conversions on mirrors.

The new argument '--log' takes either "disk" or "core"
as a parameter.  This could be expanded in the future
for additional logging types as well.

Examples:
# Creating a 2-way mirror
$> lvcreate -m1 ... # implicitly use default disk logging
$> lvcreate -m1 --log disk ... # explicit disk logging
$> lvcreate -m1 --log core ... # specify core logging
$> lvcreate -m1 --corelog ... # old way still works

# Conversion examples
$> lvconvert --log core ... # convert to core logging
$> lvconvert --log disk ... # convert to disk logging
$> lvconvert -mX --corelog ... # old way still works
$> lvconvert -mX ... # old way of converting to disk logging still works

Changes are reflected in the man pages.

25b733809a Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

a45f546fe0 o Use 'pvcreate --setphysicalvolumesize' with no short form (instead of -s)
and add severe warning if it's used to make a device seem bigger than
  it really is.  This is not an option people should be using as it
  breaks metadata integrity.
o Use uint64_t throughout (rather than unsigned long long)
o Convert a few messages that contain pathnames into the more common form:
  pathname: message

812c699c8d Basic support for persistent minor numbers;
slightly different from the current LVM1 method.

  lvcreate --persistent y  --minor 10   (to specify when created)
  lvchange --persistent n  (to turn off)
  lvchange --persistent y  --minor 11   (to change)

--persistent uses a new LV status flag stored on disk
minor number is stored on disk the same way as LVM1 does
(but major number stored is 0; any LVM1 major/minor setting gets lost)

  lvchange -ay --minor 12 (to activate using minor 12, regardless of the
                           on-disk setting, which doesn't get changed)

--minor == -m
--persistent == -M

add7dc2d5a o pvcreate --uuid to specify the uuid (required before using vgcfgrestore
onto a new device).  uuid specified must not already exist on the system.
o More message tidying.
o When checking for label, only read PV metadata.
o Add ataraid.  [Needs moving into config/defaults files.]

9f23b355f7 o Changed the macro name in args.h from 'xx' to 'arg'
o  There is now a _default_debug, and _default_verbose level, when
   using lvm interactively -vv and -dd switches just effect the current
   command.

o  Added a --quiet switch which sets both verbose and debug to zero.

8a6d1dd408 I had another look at the argument processing code:
o You must list long args with no short option (eg. --version) at the
  front of the args.h file.

o If an argument has no short option, set the short option in args.h to '\0'

o The index into the 'the_args' var is now stored as the option value
  for getopt, iff there is no short opt.
