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.

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.)

1ca18f501a o split the uuid -> device map out from vgcache
o  roll vgcache back to agk's implementation, we'll revisit this as part
   of the cluster integration.

o  change the extra_info field in a label to be a void *

45fa428bf1 Handle orphan PVs too, so hints remain valid after vgreduce. 2001-12-13 15:08:58 +00:00

d4de7934f8 Add internal cache holding a 'hint' list of the PVs belonging to each VG.
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.
