b8c919b402 o Metadata area struct change.
o Support physical extent restrictions on PV lists for allocations
    e.g. lvcreate -l 200 vg1 /dev/sda1:100-199:300-399

8ef2b021ed Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

097d49e73d i) There's now a seperate field in struct logical_volume that stores the
allocation policy.  This can currently take one of three values:

   typedef enum {
        ALLOC_NEXT_FREE,
        ALLOC_STRICT,
        ALLOC_CONTIGUOUS
   } alloc_policy_t;

    Notice that 'SIMPLE' has turned into the slightly more meaningful NEXT_FREE.

ii) Put code into display.[hc] for converting one of these enums to a
    text representation and back again.

ii) Updated the text format so this also has the alloc_policy field.

1951dba955 o Actually read snapshot percentage from the kernel - what a pain! :)
o Not sure if the code in dev_manager is really optimal, but it works..
   will look at adjusting it a bit now.
 o I *think* it works right when one snapshot if full but others aren't,
   but I haven't really been able to test it because the full snapshot
   somehow resets itself and weird things start happening to the system...

fccc39a3a7 o Added function find_snapshots to snapshot_manip.c that returns a list
of snapshots whose origin is the lv passed in.
 o Used this new function to make lvdisplay properly display all snapshots
   attached to a origin.

6e2ff7fb35 o Updated *display output for LVM1 compatibility
o There is still a bit missing
   + all are missing the {PV,VG,LV} # - that is not applicable in LVM2
   + pvdisplay doesn't show how many LVs are contained on it
   + much of the snapshot information isn't available for lvdisplay
 o Look at the code for other potiential FIXMEs  :)

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.

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.)

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

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).

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.

  PV is allocatable - free extents on it may be allocated to LVs
