Recover disk after a hard reset [unusual situation] ???
 

Hello,

I have VPS (KVM) 15GB disk. Provider somehow attached another disk (with the same older data) to this VPS. (blkid, fstab etc. here). Everything was working fine untill hardreset (hs).
After hardreset I see old data only. Do I have any chance to get to newer data on another disk?

Please see details before and after hardreset:

I would appreciate your help.

have you tried gpart (g[uess]part[ition]?
Be aware that on a large HDD, it can take hours to days, so if you don't have a battery backup, it might be a bad idea.
