f7ff4d005f Zero gap after PV structure on write to disk in order to make non LVM tools happier (AED's idea and patch for LVM1) 2002-01-29 15:52:11 +00:00

ba76e378e9 Ignore all except one PV found with the same UUID. Use one which 
has the md major number if there is such.

d518bc39f3 Avoid using VG metadata on PVs that are not in VGs. 2002-01-23 15:50:34 +00:00
Alasdair Kergon
add7dc2d5a 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.]

839f595181 Handle orphan PVs too, so hints remain valid after vgreduce. 2001-12-13 15:08:58 +00:00
Alasdair Kergon
faa556e759 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.

5238b63f1a Miscellaneous tidying 2001-11-14 13:52:38 +00:00

29aa6d5850 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.

c7f0b573ac o use dev_name(dev) to get the name of a device, this operation is cheap 
since it just get's the first alias.
