The virtual machine cannot be accessed via SSH. What should I do?
Symptom
The virtual machine responds to Ping but cannot be connected via SSH.
Cause
A storage disconnection caused an I/O error on the virtual machine, putting it in read-only mode.
Solution
-
Log in to the virtual machine console and run the following command to create a file and check whether the virtual machine is in read-only mode:
[root@localhost ~]# touch /root/zstack.txt -
If the file cannot be created, restart the virtual machine.
