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.

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!
