3d2d379ce4 Have a pe_total check using theoretically big number instead of the 
unnecessarily small limit LVM1 imposes in vgcreate (but not vgextend)

c50c2886f7 Don't bother to write out an empty cache. 2002-01-24 23:17:16 +00:00
Alasdair Kergon
b849de1d18 Fix the device cache to cope reasonably safely with device name changes. 
This should be a rare occurrence so the aim is to recover if it's
straightforward to do so, otherwise just to abort the operation.
If people *knowingly* change device names, they should always run vgscan
afterwards.

A few bytes of memory gets leaked inside a pool each time an alias
has to be discarded - it's not worth restructuring the code to reuse it.

More of LVM2 needs updating to pass device objects (or uuids) about
instead of pathnames so that resolution of pathname->object only happens
once per operation.

dev_cache_get() should now always return the *current* device at the path given

dev_name_confirmed() replaces dev_name() whenever it's important to
know that name for the device is still current (ie when opening it).
If the cache doesn't know a current name, the function fails.

dev_open() guarantees that the file descriptor returned is for the dev_t
of the device structure it was passed.

7743c8685e Clear a FIXME about checking for identical devices by comparing dev_t 
instead of name.

610c25e8b1 o Remove redundant symlink-handling code. 
o When opening device, return error if its cached name is incorrect (eg if
  it's changed since the cache was generated).  This prevents use until

- The iterator can find labels by string and also appropriate version number (==,

- 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.

c0ca88c287 o Comparison function was sorting things in ascending rather than 
descending order.

o free off the sort array when finished with it.

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.

4a8d120415 o pool-debug.c contains an alternative implementation of pool that gets 
a seperate chunk of memory from dbg_malloc for each pool_alloc.  This
   will allow the bounds checking code in dbg_malloc to do it's stuff.

o  The normal implementation moved to pool-fast.c

o  pool.c now just contains a #ifdef and includes the appropriate .c file.

Alasdair, could you make sure that gcc -MM get's passed all the
CFLAGS please, otherwise the dependencies get calculated incorrectly.

0bab65915d o Sync up todays work on converting to the segmented representation of 
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   activate.c changes.

Nothing has been near a compiler as yet.

Alasdair can you look at changing display.c to use to output the mappings
in a more segment oriented format please ?

I haven't put the span list into struct physical_volume to represent allocated
extents.  I think the burden of maintaining it for things like lv_extend may
out weigh it's uses.
