unorderly shutdowns will, even will full journaling, lead to dataloss of all
data in the buffercache. Filesystem consistency is far more important,

very sensitive to unorderly shutdowns.

AIX LVM system (even booting from a LV, though not in the most elegant
fashion thinkable) is quite mature. It is one of AIX typical features I like
