BD Backend: Volume creation support

2012-11-29T17:39:25+00:00

A new parameter type is added to volume create command. To use BD xlator
one has to specify following argument in addition to normal volume
create

device vg brick:

for example,
$ gluster volume create lv_volume device vg host:/vg1

Changes from previous version

* New type 'backend' added to volinfo structure to differentiate between
  posix and bd xlator
* Most of the volume related commands are updated to handle BD xlator,
  like add-brick, heal-brick etc refuse to work when volume is BD xlator
  type
* Only one VG (ie brick) can be specified for BD xlator during volume
  creation
* volume info shows VG info if its of type BD xlator

So lvextend binary is forked to achieve the same
