I’m using the infscape Appliance on baremetal install. It has worked great for 5+ months. Suddenly in the last couple days I’ve noticed backups taking way longer than normal and slow load times on the web interface. I checked the netdata stats today and noticed that iowait is sitting at 95-100% on the CPUs almost all the time. It was not like that a few weeks ago. I have added more endpoints to be backed up but it just seemed to go from nothing to super high very quickly rather than a gradual thing as I added more endpoints. I have included my hardware below. Does anyone have any insight on ways to fix this? Would replacing the RAID controller with one that has 1GB cache help? Or do I just need to buy an additional server and spread the load out between the two? (or more)
