This error occurs when nomount is started, so it is related to the system.
I asked my friend what actions they had recently and I couldn't recall any questions. Some time ago, the machine was always OK, that is, machine maintenance today. This problem occurs when Oracle is restarted.

Because errors occur during nomount, you can definitely judge that it is related to the system,

I checked it online. This problem occurs when the hostname is modified. I confirmed with my friend that the hostname of the machine has been modified. The reason is clear. It is easy to solve the problem. Modify the/etc/hosts file and add it to hostanme.
