Hi list, I'm running Centos 7.6 on an Corsair Force MP500 120 GB. Root fs is ext4 and this drive is ~1 year old. System works very well except on boot. During boot process I got always a file system check on nvme drive.

Running smartctl on this drive I got this:

I noticed that Unsafe shutdowns increased rapidly and I don't know why there is an unsafe shutdown. Every 3/4 boot this value is increased by 1 and I don't know why.

I can't find any errors on system logs.

Can someone point me in the right direction?

Thanks in advance.

Alessandro.
