1d3e407c8f 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.

dd2157534b 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

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.

3ed065de37 Return status from _lv_activate and friends.
Alasdair, I think this is right (and I need it) but you may like to check.

than the uuid.

0fd2ba033f o Comment out some new code that was preventing pjc activating
snapshots.  This will go back in when the active_list is working.

b2ef256910 o Add comment describing what we're aiming for with dev_manager.
o  Remove dev_manager_reactivate, since it'll be the same as activate.

o  Merge the mark, visible and dirty fields into the same flags field.

63d6ce95db 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.
