03888774a5 o Added functions to display what's in the archive.
o  For now vgcfgrestore -l <vg> displays this list.

A bit hacky, but it'll get better.

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.

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.

77712b1ecb Set pv->pe_size when reading in text-file backup.
Otherwise LVM1 decides the PV structure is corrupt.
But do we need to keep both pv->pe_size and vg->extent_size
in internal metadata or can we generate pvd->pe_size when writing out
a PV that belongs to a VG?

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
