Hi,
I've noticed today that my kernel log file is abnormaly increasing.
I took a look inside the log and i could discover the following messages are constantly appearing.
It looks like that i've a serious problem with my SSD.
But.. this volume is virtual. My UTM runs under ESXi 6.5.

Then i've connected on my VMWare shell and i've typed the command to retrieve the SMART information from my SSD.
Actually it is difficult for me to conclude that my SSD has really a problem since each value is far above its corresponding threshold value.
Or maybe i'm not looking at the right place or i do not interpret correctly those values?
