Usually this is not a problem but if you use a external journal and after a reboot the device number change will prevent the MDT from mounting. The proper solution is to add a mount option for ldiskfs to locate the journal using the device path instead of the device number.</p> MDT server with a installed RHEL6.4 distro. The MDT uses a external journal. LU-4015

Have ldiskfs handle changing device numbers for an external journal
