Hi, I assume it's this prometheus alert rule definition: - alert: "CephNodeDiskspaceWarning" annotations: description: "Mountpoint {{ $labels.mountpoint }} on {{ $labels.nodename }} will be full in less than 5 days based on the 48 hour trailing fill rate." summary: "Host filesystem free space is getting low" expr: "predict_linear(node_filesystem_free_bytes{device=~\"/.*\"}[2d], 3600 * 24 * 5) *on(instance) group_left(nodename) node_uname_info < 0" labels: oid: "1.3.6.1.4.1.50495.1.2.1.8.4" severity: "warning" type: "ceph_default" It's located on your prometheus node under /var/lib/ceph/{fsid}/prometheus.{hostname}/etc/prometheus/alerting/ceph_alerts.yml. You could try playing around with the expression to not consider all devices. You can just edit this file and then restart prometheus.

Greetings -

Forgive me if this is an elementary question - am fairly new to running CEPH. Have searched but didn’t see anything specific that came up.

Is there any way to disable the disk space warnings (CephNodeDiskspaceWarning) for specific drives or filesystems on my CEPH servers?

Running 18.2.0, installed with cephadm on Ubuntu 22.04 on Arm. Keep seeing these warnings in the Dashboard for /boot/firmware, which, in my opinion shouldn’t really be something that ceph needs to worry about - or at least, should be something I can configure it to ignore.

Thanks in advance.

Dan.
