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

5986ec940f o Removed the -z (suspend) option from the tools
o  New function: int lv_setup_cow_store(struct logical_volume *lv)
   This zeroes the start of the cow device.

o  Made lvcreate call above fn.

294ddff8a6 o snapshot support for the text format.
The logical_volumes, and snapshots sections of the text format are now
optional.

Joe Thornber
7d68b08028 o First changes to add snapshot support.
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather).  As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

fdc7af232a o Turn the device_create_* functions into device_populate_*, they only
fill in an already created dm_task.  This allows common code, such
  as minor number selection, and read_only to be lifted.

8d6a8717bb Now that most of the usage of 'stack' only occurs when there's an error,
don't suppress it from the screen output any longer.

59d6420b9a o I decided that the archive_format shouldn't really be a format at
all since it only supports vg_write.  It has been replaced with:

int archive_vg(struct volume_group *vg,
	       const char *dir,
	       const char *desc,
	       uint32_t retain_days,
	       uint32_t min_archive);

which is now called directly by tools/archive.c

e74999af51 o Add cmd_line field to struct cmd_context
o  Text format now has a description and time field at the top level.

o  archiving and backup set the description appropriately. eg,

   for an archive:

     description = "Created *before* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

   for a backup:

     description = "Created *after* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

This is preparing the way for a simple vgcfgundo command.

d6750e9d76 lv->minor >= 0 (ejt) 2002-02-04 13:08:31 +00:00
Alasdair Kergon
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

7ae5a778d5 Basic support for (read-only) partial activation if any PVs are
missing from a VG.  (Linear targets use the device-mapper 'error' target
which returns ioerror; striped targets use '/dev/ioerror' for now - which must
already exist e.g. as a sufficiently large block device version of /dev/zero).

4b2ec1929a o There were some alignment problems with pool-debug which I've resolved
by allocating the data block with an additional dbg_malloc.

o  Added an assertion to check that no one is requesting alternate
   alignment for memory allocated from pool.  I can't see us needing this
   for LVM2.
