I was able to connect to the machine, but now while working, it has shut down suddenly and I can no longer connect via ssh.
In the FIWARE cloud, the status is active and running, and I can trace the whole route to the machine.
I would appreciate your help again.
Thanks in advance

Summary: [Fiware-tech-help] FIWARE LAB Instance shutdown and won't recover
Key: HELP-6210
URL: https://jira.fiware.org/browse/HELP-6210
Project: Help-Desk
Issue Type: extRequest
Components: FIWARE-LAB-HELP
Reporter: FW External User
Assignee: José Ignacio Carretero Guarde
Hello,
Today I detected that I couldn't connect to my instance (130.206.125.211). When I went to the FIWARE LAB dashboard, I detected that the status of the machine was "SHUTDOWN", so I tried to activate, I found the following logs, where it's said that the HDD cannot be mounted. Could you please provide me a solution?
Thanks in advance

Dear José,
This seems to be a CentOS / Red Hat bug which happens after a kernel update. We are working to find out a solution to this problem.
However, we've realized that the virtualized disk is ok and there seem to be no sign of data loss.
Regards,
José Ignacio.
