Background: Once a year, I install a new drive to use in that year, call it year Y. The previous year's drive (Y-1) stays on line but read only so I can copy files from it as needed. The drive from the year before (Y-2) is retired, but I have it should I ever need to go back to it. That works just fine for non-LVM encrypted drives.
Last year I used LVM and encrypted (dm-mod) it. This year, I did the same. I can boot to either Y or Y-1, but which ever one I boot too, I can't read the other. On hard drive Y, how do I make the physical volume on Y-1 visible? fdisk -lu reveals a partition on Y-1 which is marked as "8e Linux LVM". pvscan only shows one PV. Judging both by the size and by the fact that it's the one in use, I think it is showing the PV on Y. root@dzur:~# pvscan PV /dev/dm-0 VG dzur lvm2 [1.82 TiB / 0 free] Total: 1 [1.82 TiB] / in use: 1 [1.82 TiB] / in no VG: 0 [0 ] root@dzur:~# pvs --all PV VG Fmt Attr PSize PFree /dev/dm-0 dzur lvm2 a- 1.82t 0 /dev/dm-2 -- 0 0 /dev/root -- 0 0 /dev/sda1 -- 0 0 /dev/sda2 -- 0 0 /dev/sda3 -- 0 0 /dev/sdb1 -- 0 0 /dev/sdb5 -- 0 0 root@dzur:~# I conjecture the physical volume I want is on dm-2.
