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 > > That vgimport fails might be caused by out-of-sequence physical volume > number.
