New Revision: 246175
URL: http://svnweb.freebsd.org/changeset/base/246175

Log:
  MFC r245341:
  Windows handles INIT and VERIFY as array-wide and it doesn't specify which
  disks should be rebuilt. Our rebuild code is same time disk-centric.  To
  handle this situation  properly check all disks for RBLD flags, and if no
  disk specified try rebuild/resync all of them except newly inserted.
