XEN. After the reboot, Local Storage does not join. How to raise?

Question

Xen

Hello! Please help me. I don't understand Xen virtualization, the server is still from the previous admin. After turning off the light, Local Storage did not join. I looked around the forums, nothing helps, but I'm not sure if I dug in the right direction or not. In general, I'm sorry, I'm such a teapot. Please help if you can..Thank you!

Well, I think it's worth starting with what localstorage physically is, what is it a separate disk, a raid array, a partition on a disk? Where is the xen server installed: on a separate disk, on a partition? Perhaps your hard drive failed after turning off the light.

Answer 3

What type are you using for LocalStorage? LVM or EXT3?
If LVM and the problem is not hard, you can try to restore the section table:
habrahabr.ru/post/254011
For this reason, you need to set "archive=1" in /etc/lvm/lvm.conf
Once I had to be pretty nervous, but the sections were pulled out.
Good luck!
