SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2)
rename '/dev/root.tmp-b254:0' '/dev/root' failed appears when the system start on a LVM configured host.
1. Since LVM VG's create /dev entries with the same name, do not choose VG names which may be used by other devices or services.
2. The /dev/root link provided by the systemd-udev-root-symlink service is currently deprecated and will be removed from future systemd versions.
The /dev/root symlink created is not currently used by any system components. As such, if a customer environment also does not make use of the /dev/root symlink, the systemd-udev-root-symlink service may be masked with the command:
systemctl mask systemd-udev-root-symlink.service
The system administrator should exercise caution in choosing VG names to ensure such collisions do not occur.
