Hi,
I have a PVE server with two VMs.
Tonight at about 23.40, the VM100s shut down and I had to manually reboot.
In the logs I found the following:
Apr 07 23:35:18 pve smartd[2326]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 121 to 122

Can you help me to interpret the log?
