[LUAU] Linux HD Recovery

[John S. Johnson]

One of my favorite things about going away to events like CES is the opportunity to flirt with disaster recovery. Usually the extent of our disaster is a HECO-induced blackout that requires a power button press to solve everything. This time, however, a capacitor on my motherboard blew and said linux system went bye-bye. In an ideal world I would have recently backed up my files and Postgres database. In reality, I hadn't. The drive is still intact and I figured I would hook it up to another linux box via an external USB enclosure. When I connect the drive and look at it with fdisk, I notice it has a small boot partition(type Linux) and the rest is a Linux LVM partition. In /etc/fstab I tried to set up both /dev/sdb1(boot) and /dev/sdb2(rest) with the following lines:
/dev/sdb1   /mnt/tempdrive       auto  defaults, ro  0 0 
/dev/sdb2   /mnt/tempdrive2       auto  defaults, ro  0 0 
I can mount sdb1 but sdb2 flags me with the error:
mount: you must specify the filesystem type
 
Looking at the drive with fdisk shows me that sdb1 is Linux and sdb2 is a Linux LVM drive...any ideas on how to get sdb2 mounted? Thanks in advance!!
 
Sincerely,
