input / output error on /etc/pve

Hi Guys,

Just a quick question, I'm getting input / output errors on /etc/pve aka /dev/fuse.

This server is a single server not a node / cluster or anything. If i did /etc/init.d/pve-cluster restart what would happen, baring in mind this is a live server with live vm's that I can not take down. Also would this fix the input / output errors?


Thanks
Paul
