Re: md: can not impport hdb1, has active inodes!

[Cameron Moore <lists@unbeatenpath.net>]

I've been battling the same problem using Debian testing/sarge with SCSI
devices.  I followed (mostly) the same howto and have subsequently tried
many other things with no success.  I'm willing to help debug this as
well if anyone has any advice.  Thanks
