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.

39ed033adb o the _status fxns now take more arguments - this way i don't get the 
preparsed status info, shove it all into a string, and then parse it
   again to get the info back out (which is what i was doing before)
 o basically that's it...i like this *much* better than the previous
   method and i think it makes the _status fxn more flexible if we need
   to use it to get other info out.

   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...

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.

snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

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
 2002-02-08 11:58:18 +00:00
Joe Thornber
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.

Alasdair Kergon
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

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.

  they do not match.
- Write labels in sector 1 & last rather than 2 & last as per Joe.

   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.

12eabe3031 o composite filter that allows us to merge filters. Think of it as &&'ing 
filters in order.

eg,

	f = composite_filter_create(2, regex_filter, persistent_filter);

  ownership of the filters passes, they will be destroyed when f's
  destroy method is called.

5f16718b19 o Filter which caches valid devices in a file. Pass in init == 1 to the 
constructor if you want it to ignore the existing cache and check every
  device again (eg, vgscan, pvscan).

devices {

        # first match is final, eg.  /dev/ide/cdrom
		        # get's rejected due to the first pattern

					filter=["r/cdrom/",         # don't touch the music !
							"a/hd[a-d][0-9]+/",
							"a/ide/",
							"a/sd/",
							"a/md/",
							"a|loop/[0-9]+|", # accept devfs style loop back
							"r/loop/",        # and reject old style
							"a/dasd/",
							"a/dac960/",
							"a/nbd/",
							"a/ida/",
							"a/cciss/",
							"a/ubd/",
							"r/.*/"] # reject all others
}


Alasdair this is ready to roll into the tools now.

d1b28647ed o First pass at the regex code. lib/regex/matcher takes an array of regex's 
and builds a *very* efficient engine that will tell you which regex a string
  matches with only a single pass through the string.  To be used in the config
  file when specifying devices.

o Anchor's aren't supported yet (^ and $) but that won't take long.

o Also when we get some realistic config files we may want to consider adding an
  extra level of indirection to the dfa state in order to compress the table.
  It all depends on how large typical tables get.
