c4856caebb Preparation for an LVM2 liblvm - pass cmd_context into each tool and
link some globals that the tools need into that structure.

fc1030bb22 Now that most of the usage of 'stack' only occurs when there's an error,
don't suppress it from the screen output any longer.

a56fa1558b o Split activate.c into a high level (remaining in activate.c) and low level (ll-activate.[hc]) API.

286a79d94d 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.

138a27570b 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

c2ed40a74f 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.

71958bc0f1 lv->minor >= 0 (ejt) 2002-02-04 13:08:31 +00:00
Alasdair Kergon
366ec35612 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

0800dcfdc4 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).

089b5052e6 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.

Alasdair Kergon
e1c24bd5a2 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?

45b7322488 Don't bother to write out an empty cache. 2002-01-24 23:17:16 +00:00
Alasdair Kergon
b3055e992f 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.

3da548565c Clear a FIXME about checking for identical devices by comparing dev_t

f7912d88b1 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 cache is rebuilt (eg with vgscan).  Doesn't catch every case.
