Problem Description

I have a daily backup script that creates a snapshot then reads it & uploads to backblaze. ZFS automatically mounts a snapshot when you read from it. You can see the disk usage with iotop/htop but it doesn't appear in the graph for my ZFS pool.

For example I can see 30 MB/s read in htop but my pool appears idle.

Expected Behavior

Reading a snapshot under the hidden .zfs directory should show the read/s on the ZFS pool graph since it's still reading from the pool.

Steps to Reproduce

  1. zfs snapshot mypool@test
  2. navigate to /mypool/.zfs/snapshot/test
  3. do some reads
  4. verify htop/iotop doesn't match beszel
