I'm actually not sure I'm reading this right, but I don't think you want to dd to an NFS share? Maybe you meant "XFS should match correctly?"
If you're trying to do it over a network, I would have thought you'd have more luck by piping dd through an nc connection, then dd back to a disk on the target ie, on old server : dd if=/dev/vg1/lv1 conv=noerror,sync | nc NEWSERVER PORT on new server: nc -l PORT | dd of=/dev/vg/lv01 Also I'm not sure how the LVM is going to interact because I don't tend to use LVM on my production servers with XFS On Wed, May 13, 2009 at 7:14 PM, Ken Foskey <fos...@tpg.com.au> wrote: > > I have a very large xfs file system that is corrupt and there is an IO > error in the middle of the file system, xfs_repair crashes.
