My 8 year old computer with fc22 died. I have a new computer now running fc25. I had routinely backed up my most important data, so not all is lost, but I would like to look at what I have on my old disk.
I have a usb enclosure and put my old disk in it. It generates /dev/sdb1 and /dev/sdb2 on plugging in. The /dev/sdb1 partition is immediately accessible and it held /boot. The /dev/sdb2 was broken into partitions logically. Unfortunately, the volume group name given was "fedora". That is the same name given to the disk running my fc25 system. Output from pvs is
PV VG Fmt Attr PSize PFree /dev/sda3 fedora lvm2 a-- 928.51g 0 /dev/sdb2 fedora lvm2 a-- 465.27g 4.00m
It is the second volume group that I want to get at.
Output from vgdisplay shows both "fedora" volume groups:
The info from each group is relatively boring except the last line. For one volume I get:
VG UUID nMitQe-QmR1-tBP7-CTqm-VBR3-zUj5-UuTIml
and for the other I get:
VG UUID 0Fuho1-nVos-nYkZ-HFih-hPSK-dilF-AIDaxI
Of course both volumes show the VG name as "fedora".
That difference in UUID is my ray of hope that I can get to the data on the volume in the enclosure. A direct
# mount /dev/fedora/home /mountpoint
does not get what I want. It just gives me a second mount of my fc25 disk, and not the disk in the enclosure.
Does anyone know how to exploit the info I have given to give me access to the logical volumes in the second partition of the disk in the enclosure?
