Hi guys!
I have server with 4 nvme disks that formatted in btrfs raid.
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

Hi @Stanislav_Rybak
No worries, i think your disk is ok
utilization and backlog are Field 10 and Field 11 from /proc/diskstats.
Let’s do the following
for ((i=0; i<10; i++)); do cat /proc/diskstats; echo; sleep 1; done

Ok, i see, then both those metrics has no sense for you. I believe you can ignore both alarms (they are to: silent, so you see them on the dashboard only).
That utilization in fact is busy_ms, 100% busy doesn’t mean the disk can handle no more additional operations.
Hi @ilyam8 , thanks for the quick reply!
So, if I understand correctly, this checks does not really work for raid setups?
Output of the command you suggested above(I only show numbers related to nvme disks):

Look at #5744 (comment) . In your case, the problem is the same - wrong major and minor numbers.

You can delete the alarms (they are not accurate anyway) or try applying #5799 as a temporary workaround, but in general, it is better to look for a correctly working NVMe driver.

Hey @vlvkobal ,
What do you mean that the alarms are not accurate? I know that we are working on improving our sane defaults, so should I ping product to look into these alarms as well?
Hi @vlvkobal , thanks for the explanation.
I was checking github issue, where you mention that this issue with specific kernel version.5.8.0 version. I also saw some reports that changing io scheduler for nvme disk may show correct values, but apparently I already haveis set:
sudo cat /sys/block/nvme0c0n1/queue/scheduler
[none] mq-deadline

As you see there is correct major and minor device numbers, but they, not actually display any usage data.
Disk utilization can be misleading depending on actual hardware. There is nothing we can do to improve it.
@Stanislav_Rybak can you show the whole content of /proc/diskstats, /proc/self/mountinfo, and ls -al /sys/dev/block?
