Something that I thought would be simple turned out ta not ta be simple at all. What's new.
Anyway, the outputs:

I thought I was doing a simple install to a new disk. I use openSUSE and I thougt that I could install with the old disk unplugged then plug in the old disk and boot the new system then access the old home partition to retrieve my data, settings, etc.
The Partitoiner in Yast tells me that it will not mount a partition with unknown or non-existent file system. I'm pretty sure the filesystem is still there and I want to be careful to keep it intact. I'm not practiced enough to go it on my own.
/sda is my new disk 500 Gib it is working correctly as far as I can tell.
/sdb is my old disk and /sdb3 is the partition I want to mount.
in pvscan there is a mistake where there is only 1.5 Tib disk space in my machine.
I used Yast Partitioner to change the Volume Group names I think.
I'm still a little unclear about the distinction between PVs and LVs and VGs, but I'm starting to get it.
I'm paranoid to try anything else lest I lose my data.
Anyway, whatever help I can get would be greatly appreciated.
Thanks,
AARON
