dd2157534b Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

0e43107c87 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.

archive_vg is called.

63875e7591 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.

950d9d6ee7 Missing seg->lv gives segfault when activating from text format. 2002-04-16 19:41:54 +00:00
Alasdair Kergon
fc8b7efc6f o Use new LCK_HOLD flag to indicate whether lock should be held on return
from lock_vol() - otherwise it now attempts to acquire the lock and then
  immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
  for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible.  (Another
  step towards using them instead of VG names internally.)

de7f7b96db o Format1 wasn't recording the snapshot chunk size properly
o  Activation of snapshots now works - though the resulting device
   doesn't (pjc ?)

o  text format wasn't setting vg->cmd.

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.

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).

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?

34458e0c57 o Changed
struct pv_list {
	struct list list;
	struct physical_volume pv;
   };

   to

   struct pv_list {
	struct list list;
	struct physical_volume *pv;
   };


o  New function in toollib 'create_pv_list', which creates a list of pv's
   from a given command line array of pv's.

o  Changed lvcreate/extend to use this (fixes lvextend [pv list] bug).

c46d20fa92 o pvcreate --uuid to specify the uuid (required before using vgcfgrestore
onto a new device).  uuid specified must not already exist on the system.
o More message tidying.
o When checking for label, only read PV metadata.
o Add ataraid.  [Needs moving into config/defaults files.]

0092790c7d 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.
