[lvm-devel] [PATCH] Remove LV if zeroing was requested but failed

[Jun'ichi Nomura]

If zeroing of LV was requested for lvcreate but failed,
it seems nicer if the lvcreate fails and the (incomplete) LV is removed.

Attached patch changes lvcreate to abort in the following cases:
  - if zeroing was requested but activation was disabled
  - if zeroing was requested but activation failed,
  - if zeroing was requested but zeroing failed

A test script is also attached.

Thanks,
