sparse: configurable type for sparse volumes
Support compile type configurable defaults for creation of sparse volumes. By default now create 'thin-pools' for sparse volumes. Use the global/sparse_segtype_default to switch back to old snapshots if needed. Apply the same compile logic for newly introduces mirror/raid1 options.

Version 2.02.112 -
|
||||
=====================================
|
||||
Configurable support for creation of sparse volumes with thin-pools.
|
||||
Update and correct lvcreate and lvcovert man pages.
|
||||
Mark pools and snapshots as unzeroable volumes.
|
||||
Check for zeroing of volume after segment type is fully detected.
