Well, sort of. When I actually tried it out, I got an error message
from LVM 0.8.1's vgscan:
vgscan -- ERROR "lvm_remouverecursive(): opendir" removing volume group director
y and special files
vgscan -- ERROR "lvm_remouverecursive(): opendir" creating "/etc/lvmtab" and "/e
tc/lvmtab.d"
vgscan -d showed me an interesting thing:
<4444> vg_check_name -- vg_name: "5HozPsvN3ueT3iLNQpeAE08HISKPy1O7"
First I thought that bogous vg_name may be caused by data corruption, until
I noticed that the string above is 0.9's uuid of that VG.
I didn't try to fix the bug as 0.9 is fine for me.
The above happend with some random -testxx-preyy kernel, so it may be
caused by something completely different. I'm just not as sure as I was
before that going back from 0.9 to 0.8 is possibly without any problems.
