I have server with 4 nvme disks that formatted in
I only mount one root btrfs subvolume, with simple command like this
mount /dev/nvme0n1 /home
My problem is that Netdata reporting wrong disk usage(at least I think and hope that it’s wrong :slight_smile )
For example, it show that
nvme0n1 has 100% disk utilization. But I cannot see it with other tools, like
iostat. This is output of iostat on
nvme0n1 disk show something close to ~2%util, when netdata reporting 100% util.
Netdata also show that my disk backlog is 94:33:22.
Is there a way for me to confirm this util and disk backlog with some linux tools? I don’t see any slowness during server usage, so I wondering if this netdata checks are correct
