Cheers. I'll post this back to the list for now. I'll sort out those other
questions later :)

er.. but i can't mount the xfs filesystem due to the 512byte blocksize....

ok. This is what i get (all you non-linux types forgive the linux notations -
i've read quite a bit of the news groups :)
/dev/hdb is an 9 GB IDE disk, contents (currently) ext2 however it's not
and it's ready to be blanked by whatever happens next
Disk /dev/hdb: 128 heads, 63 sectors, 782 cylinders
Units = cylinders of 8064 * 512 bytes

/dev/hdb1 * 1 740 2983648+ 83 Linux
/dev/hdb2 741 782 169344 82 Linux swap
/dev/sda is a 4 GB SCSI disk from the Octane.

Fair enough. OK. So we attempt to 'dump' the filesystem from my unreadable
(512bytes blocksize) xfs disk (i'm deliberately not using the word partition as
normally would) to the IDE drive (not currently xfs, but ext2). Neither are
xfsdump -f /dev/hdb1 -b 512 /dev/sda1
after being prompted for a label i get the following error :
xfsdump: ERROR: /dev/sda1 does not identify a file system
which suggests to me that xfsdump cannot read the filesystem due to this 512byte
!= 4096byte incompatability with the SGI Octane disk and the linux XFS driver.
I get this also with the following command line variations :
xfsdump -f /dev/hdb1 -b 512 /dev/sda
xfsdump -f /dev/hdb1 /dev/sda
xfsdump -f /dev/hdb1 /dev/sda1
Could anyone offer any help/advice.
