Filesystem for Disk I/O stats

[gehrleib]

Description

I can't seem to get any disk I/O stats using Unraid. I've tried variations of

/dev/md1p1
/mnt/disk1
shfs
/mnt/user0
etc..

OS / Architecture

Beszel version

0.9.1

Installation method

With Docker you should mount a directory in /extra-filesystems instead of using the env var:

volumes:
  - /mnt/disk1/.beszel:/extra-filesystems/md1p1:ro
  - /mnt/disk2/.beszel:/extra-filesystems/md2p1:ro

Edit: Nevermind, reading is hard. What's your output of lsblk?

This is my lsblk

Which one do you want to use as the root disk? md1p1?

[gehrleib]

There is no way to look at the array as a whole, right? If so, md1p1 is fine.

Do I just put "md1p1" instead of "/dev/md1p1"?

When using docker the agent can only see devices that are mounted in the container.

It looks like maybe nvme0n1 is the current root disk where the container storage is? If so, you need to mount a folder from /mnt/disk1 in the container as shown above. That will provide access to the device, then you can use the FILESYSTEM env var to override the root disk.

I recommend adding LOG_LEVEL=debug to the agent temporarily. Then check the logs on startup for the lines starting with DEBUG Disk partitions and DEBUG Disk I/O diskstats. That will show you all devices the agent can see.

Great, I'll try this in the morning
