for various reasons I can not just set up new nodes and extend the cluster,
I need to replace it. Wrong machines, wrong disks, you get the idea.
Now, the current setup is distributed replication setup with two disks on
two nodes like that: a:b, A:B
The new setup will be two nodes with four disks: a:b:c:d, A:B:C:D
can i just cp -a the contents of my original setup on the corresponding
disks in the new setup? Will the extended attributes be correct? If not,
what would be the issues?
