Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)

a9dbabe07e o the _status fxns now take more arguments - this way i don't get the 
preparsed status info, shove it all into a string, and then parse it
   again to get the info back out (which is what i was doing before)
 o basically that's it...i like this *much* better than the previous
   method and i think it makes the _status fxn more flexible if we need
   to use it to get other info out.

02543bad1c o Actually read snapshot percentage from the kernel - what a pain! :) 
o Not sure if the code in dev_manager is really optimal, but it works..
   will look at adjusting it a bit now.
 o I *think* it works right when one snapshot if full but others aren't,
   but I haven't really been able to test it because the full snapshot
   somehow resets itself and weird things start happening to the system...

46127e673d Some partial VG support with format_text. 2002-04-30 17:12:37 +00:00
Alasdair Kergon
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.

 2002-03-07 15:29:31 +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.)
