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