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

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).

6435b49153 o Basic support for exporting (but importing not completed yet).

e210599fa6 o Similar changes for lv_list. 2002-01-21 16:49:32 +00:00
Joe Thornber
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.]

7e77a31b96 o missing labeller free
o updated vgcfgrestore args
o change _check_for_open_devices only to check devices present in the hash
  table instead of using dev_iter which triggers a full scan even when only
  displaying command line help

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 *

b06f6b9545 o LVM1 labeller. 2002-01-14 10:00:56 +00:00
Alasdair Kergon
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.

f8b6e5b414 Clarify terminology:
VG is resizeable  - PVs can be added or removed
  PV is allocatable - free extents on it may be allocated to LVs

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

Joe Thornber
b31dc66628 o Sync up todays work on converting to the segmented representation of
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   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.

0b6d132759 Miscellaneous tidying 2001-11-14 13:52:38 +00:00
Joe Thornber
3d95cfb367 o Added dev_open and dev_close functions
o  Changed disk-rep to use these

o  if NDEBUG is not defined the dev_cache will check for open devices on
   teardown.

I was hoping this would speed things up.  But I'm still getting:

reti:/home/joe/sistina/LVM2/tools# time ./lvm vgchange -a n
  Volume group vg0 successfully changed

real    0m5.751s
user    0m0.060s
sys     0m0.070s

even though I have only 1 device with the vg on it passing the filters.
