288adea256 o missing labeller free 
o updated vgcfgrestore args
o change _check_for_open_devices only to check devices present in the hash
  table instead of using dev_iter which triggers a full scan even when only
  displaying command line help

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.

Joe Thornber
fc63d04f42 o Moved the current label.[hc] sideways to lvm2_label.[hc]

515df8784a Write the location of both labels in the labels so we can check them. I don't do 
much with this ATM (apart from check that they all match up).
Use a different CRC routine.

839f595181 Handle orphan PVs too, so hints remain valid after vgreduce. 2001-12-13 15:08:58 +00:00
Patrick Caulfield
75f7aa5563 made the hard-coded 512 into BLOCK_SIZE just for neatness sake. 
log_error() if writing the label fails so someone knows which was in error.
 2001-12-13 08:40:47 +00:00
Alasdair Kergon
faa556e759 Add internal cache holding a 'hint' list of the PVs belonging to each VG. 
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.

Patrick Caulfield
f4a7ce7c49 - Change label format to include a string disk_type and a version number. 
- The iterator can find labels by string and also appropriate version number (==,
  <= or any) if you want.
- Add labels_match() call that compares the two labels and returns an error if
  they do not match.
- Write labels in sector 1 & last rather than 2 & last as per Joe.

descending order.

o free off the sort array when finished with it.

Joe Thornber
488a58a998 o Striped allocator 
o  Changed pv_map.c to maintain the list of free areas in size order, which
   is more helpful to the allocators.  If you want to allocate a bit of an
   area call consume_area(area, size), this will adjust the area if there's
   some space left and shuffle it to the correct place in the list.


Not tested.
