I've taken a look at the physical extent count and hde, hdb1, hdc1 agree
on what it should be. During my hexediting, I changed hdg1 to match the
other three. Is there a way that I can calculate or scan the true PE
count so I can compare it to the number stored at the top of the PVs?
Also, in case you missed it, I listed the other changes that I made via
hexediting a couple of postings back.
I'm too, along with a recent poster, am interested implementation
documentation. Specifically, at what offset does lvm end and the actual
filesystem and data begin?
Thank you,
Emmanuel
