README_RAID.TXT unexpectedly clones disk identifier
by guanx from LinuxQuestions.org on (#5EZ7P)
The command provided for convenience to clone partitions of member disks:
Code:Now that /dev/sda is partitioned as appropriate, copy the partitions to all
the other drives to be used in your RAID arrays.
An easy way to do this is:
sfdisk -d /dev/sda | sfdisk --Linux /dev/sdb
This will destroy all partitions on /dev/sdb, and replicate /dev/sda's
partition setup onto it.also clones the disk identifier, which causes management problems. It would be nice to add a command here to reset the disk identifier to some other random value, or just don't clone that.
