XFS with an external log device does not always mount

Issue

• Filesystem logdev device causes a no boot scenario with sd device names in fstab for logdev
• Sometimes the filesystem is mountable, but sometimes it is not.
• When the expected sd device name changes, the system fails to boot to completion.
• Below is an example /etc/fstab resembling such a setup:

/dev/mapper/vg_satellite-lv_info1      /var/lib/info1   xfs     defaults,logdev=/dev/sdg1,noatime       1 2
/dev/mapper/vg_satellite-lv_info2      /var/lib/info2   xfs     defaults,logdev=/dev/sdn1,noatime       1 2
/dev/mapper/vg_satellite-lv_data1      /var/lib/data1   xfs     defaults,logdev=/dev/sdk2,noatime       1 2
/dev/mapper/vg_satellite-lv_data2      /var/lib/data2   xfs     defaults,logdev=/dev/sdz2,noatime       1 2
