Version 2.02.97 -
===============================
Update man pages with --activate ay option and auto_activation_volume_list.
Fix _alloc_parallel_area to avoid picking already-full areas for raid devices.
Use vgchange -aay instead of vgchange -ay in clmvd init script.
Add activation/auto_activation_volume_list to lvm.conf.

By default, new Logical Volumes are activated (\fB-a\fIy\fR).
If it is possible technically, \fB-a\fIn\fR will leave the new Logical
Volume inactive. But for example, snapshots can only be created
in the active state so \fB\-a\fIn\fR cannot be used with \fB\-\-snapshot\fP.
Normally the \fB\-\-zero n\fP argument has to be supplied too because
zeroing (the default behaviour) also requires activation.

If autoactivation option is used (\fB\-a\fIay\fR), the logical volume is
