Hi,
are you using zfs? There is a bug report about a zfs related issue that might explain this output in our issue tracker already [1].

You can check your current ARC-usage with: arc_summary -s arc on the host.

More context would be good.

The screenshots in your first post are from hpe1, which uses ZFS (local-zfs storage).

The screenshot in your second post is from hpe2 and you say you set it up with ext4.
So do I understand correct, that hpe2 has no disks with ZFS at all, but the ARC-cache is nevertheless utilized?

Can you please post the output of zpool status from hpe2?

No, I just reinstalled the hpe1. but hpe2 has zfs disk.
