blind guess, lvm sometime do block device scan and search for metadata, u happen to have nbd module available or compiled in kernel. so if you set a skip list for all u nbd devices, or disable the nbd in u kernel, u might be able to solve this. but nbd code should check if nbdX is configured or not. ming On Wed, 2006-05-17 at 11:52 -0400, Ricardo Sanchez wrote: > Toby > > Thanks for the reply.
