15c325f06a o Use new LCK_HOLD flag to indicate whether lock should be held on return
from lock_vol() - otherwise it now attempts to acquire the lock and then
  immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
  for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible.  (Another
  step towards using them instead of VG names internally.)

841da63e77 o Format1 wasn't recording the snapshot chunk size properly
o  Activation of snapshots now works - though the resulting device
   doesn't (pjc ?)

o  text format wasn't setting vg->cmd.

187cf4c97d o Convert lv->id back to lv_number when writing back to disk

o Use lv_number for refs to snapshots
o Update persistent minor logic after the lvcreate restructure
o Reset all parameters before use in lvcreate.

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

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.

60274aba6e Preparation for an LVM2 liblvm - pass cmd_context into each tool and
link some globals that the tools need into that structure.

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).

cc282870dd o Changed
struct pv_list {
	struct list list;
	struct physical_volume pv;
   };

   to

   struct pv_list {
	struct list list;
	struct physical_volume *pv;
   };


o  New function in toollib 'create_pv_list', which creates a list of pv's
   from a given command line array of pv's.

o  Changed lvcreate/extend to use this (fixes lvextend [pv list] bug).

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.]

288adea256 o missing labeller free

o  roll vgcache back to agk's implementation, we'll revisit this as part
   of the cluster integration.

Alasdair Kergon
4a624ca055 o ACTIVE is no longer a status flag - lv_active() used to check if an LV
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
  active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.
