LVM from Fedora to ClearOS


Hello All,

I hope you can help. I have a problem with LVM.

I have reinstalled my server with ClearOS from Fedora 17 as I felt that Fedora wasn't right for my needs.

Anyway the installation went well but I am having an issue with my LVM partition that was on the previous install.

I have 3 disks:
80GB - OS disk
2TB - Files disk
2TB - Files disk


[root@fileserver ~]# pvscan
PV /dev/sda2 VG vg_fileserver lvm2 [74.04 GiB / 0 free]
PV /dev/sdb1 lvm2 [1.82 TiB]
PV /dev/sdc1 lvm2 [1.82 TiB]
Total: 3 [3.71 TiB] / in use: 1 [74.04 GiB] / in no VG: 2 [3.64 TiB]

/dev/sdb1 and /dev/sdc1 were part of the same LVM but the Volume group name is missing.

I'm guessing that you need to recreate the volume group with vgcreate however I am worried that I this might delete the files already on there. Does anyone know how to recreate the LVM without losing the data on the disk? I have done some reading on this however haven't found the solution. Your help would be much appreciated. Thank you

Are we to assume you reformatted the OS disk without first saving the /etc/lvm/backup ?.
Try this to get the vg and lvs back as-is
Code:
vgchange -ay

Hasn't worked.Looks like it may be completely messed up. I'm attempting to use testdisk to get files back. But is not looking promising. Luckily I use crashplan so most of the important stuff should be backed up. I think I have learnt the hard way on this one. At least I know that LVM is not as simple to transfer to another server like standard partitions.

here is an article I've referred people to before, and gives a good idea of what LVM needs to work. Might give you some ideas.
I'm not a huge fan of LVM, but I wouldn't expect just mangling the OS to cause you to lose data is a separate LVM.
