The partition table has been altered!
NOTE: Follow these rules:
• Do not try to use LVM to configure the lock LUN.
• The partition type must be 83.
• Do not create any filesystem on the partition used for the lock LUN.
• Do not use md to configure multiple paths to the lock LUN.
To transfer the disk partition format to other nodes in the cluster use the command:
sfdisk -R <device>
where <device> corresponds to the same physical device as on the first node. For
example, if /dev/sdc is the device name on the other nodes use the command:
