Description
Incorrect MTU mismatch warning¶
We're currently getting a lot of MTU mismatch warnings in 16.2.5 indicating a mismatch in MTU on our OSD nodes.
In our case this is actually correct, we have 4 NICs per OSD server, 2 of which are bonded with LACP as our cluster network (MTU 9000) and 2 of which are our public network (MTU 1500).
We also noticed that even though this alert has been muted, we're still getting popups every few seconds.
Environment¶

string: ceph version 16.2.5 (0883bdea7337b95e4b611c768c0279868462204a) pacific (stable)- Platform (OS/distro/release): Debian (Running ceph containerized)
- Cluster details (nodes, monitors, OSDs): 3 mons, 4 OSDs
- Browser used (e.g.:
