I had to reinstall CentOS on a system with a separate disk array for data. I installed on the OS disks and kept the other disk array as storage (so they were not formatted).
When I try to mount the disks, I'm blocked due to unknown filesystem lvm2.
First some background. The system has two arrays of drives. One is for the OS (CentOS 6), the other for Data. Here is the physical disk count on the machine:
# Description Total Gigs 2 HARD DRIVE, 300GB, SAS6, 10, 2.5, H-CE, E/C 600 6 HARD DRIVE, 600G, SAS6, 10, 2.5, W-SIR, E/C 3600
The two smaller drives are mirrored as 300g - this is where the OS lives.
The volume names are not listed when using
PV VG Fmt Att PSize PFree /dev/sda5 vg_ursula lvm2 a-- 276g 0 /dev/sdb1 lvm2 --- 1.8t 1.8t /dev/sdc1 lvm2 --- 948g 948.67g
The PSize and PFree lines worry me.
Here's output from
PV /dev/sda5 VG vg_ursula lvm2 [276.34 GiB / 0 free] PV /dev/sdb1 lvm2 [1.80 TiB] PV /dev/sdc1 lvm2 [948.67 GiB] Total: 3 [3.00 TiB] / in use: 1 [276.34 GiB] / in no VG: 2 [2.73 TiB]

Reading all physical volumes. This may take a while... Found volume group "vg_ursula" using metadata type lvm2
partial output from

When installing this OS, I only moved the 276g drive to the "Install" list and left the other two as storage only. When I reviewed the format/partition settigns, the two storage drives did not have a check under the Format column.
What are my next steps to mount and get the data from the other drives?
