851002b87d Fix vgsplit for lvm1 format (set and validate VG name in PVs metadata).

5b61ca7281 When lvconvert allocates a mirror log, respect parallel area constraints. 
Use loop to iterate through the now-ordered policy list in _allocate().
Check for failure to allocate just the mirror log.
Introduce calc_area_multiple().
Support mirror log allocation when there is only one PV: area_count now 0.

(See lvm-devel list archives for further details.)

5a52dca9c2 Some new features. 2002-11-18 14:04:08 +00:00
Joe Thornber
7cc602c800 i) Add the VISIBLE flag to the text format. (Other changes are pending 
for lib/activate.)
 2002-07-11 15:28:49 +00:00
Joe Thornber
291906a208 i) Added a little macro to aid defining the status flags. 2002-07-11 14:36:45 +00:00
Joe Thornber
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.
 2002-07-11 14:21:49 +00:00
AJ Lewis
fccc39a3a7 o Added function find_snapshots to snapshot_manip.c that returns a list 
of snapshots whose origin is the lv passed in.
 o Used this new function to make lvdisplay properly display all snapshots
   attached to a origin.
 2002-05-08 16:57:46 +00:00

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.
 2002-04-24 18:20:51 +00:00
Alasdair Kergon
15c325f06a 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.)
 2002-03-05 20:03:09 +00:00
Alasdair Kergon
413cc9189e Begin conversion so LV id is passed to activation unit instead of 
struct logical_volume.
 2002-02-25 12:56:16 +00:00

Alasdair Kergon
b6afcf6458 Remove VG arg from lv_is_cow() and lv_is_origin() - use lv->vg instead. 2002-02-20 19:04:55 +00:00
Heinz Mauelshagen
f48d3bcbd0 First cut on "pvcreate -s" 2002-02-15 01:26:16 +00:00
Joe Thornber
0a9f8bcf97 o First pass at format1 snapshot support. 2002-02-13 11:43:29 +00:00
Joe Thornber
7d68b08028 o First changes to add snapshot support. 
I'm taking a different route from LVM1 here in that snapshots are a
seperate entity from the logical volumes, I think of them as an
application of an LV (or two lvs rather).  As such there is a list of
snapshots held against the vg, and there is *not* a SNAPSHOT, or
SHAPSHOT_ORG flag in lv->status.

60274aba6e Preparation for an LVM2 liblvm - pass cmd_context into each tool and 
link some globals that the tools need into that structure.
 2002-02-11 20:50:53 +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.
