a9953411a8 o Rejig activation code device dependencies to make things a bit more robust
and further reduce the number of ioctl calls made.
o Metadata area struct change.
o Make config file accessible to activation functions & get stripe_filler
  from it.
o Allow kernel to return snapshot status as a fraction or a percentage.

8ef2b021ed Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

39ed033adb 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.

1951dba955 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...

6b4c9ff740 Some partial VG support with format_text. 2002-04-30 17:12:37 +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.

584404f8f4 Return status from _lv_activate and friends.
Alasdair, I think this is right (and I need it) but you may like to check.

eea1d6932c o Top level device is now just called <vg>-<lv> (there's no 'top'
layer appended).

o  Got rid of the unused layer->type field and enum.
