Feature #20087

Updated by Vikhyat Umrao almost 7 years ago

- OSD: Add heartbeat message for Jumbo Frames(MTU 9000)

- When we have jumbo frames enabled in cluster network and if MTU is not configured properly like the recommendation is all interconnecting network gear must also have jumbo frames enabled but if any device is misconfigured for jumbo frames then we see a lot of issues like peering stuck, slow requests and backfilling not progressing.

- And the issue is we do not see heartbeat timeout messages in the OSD logs because heartbeat messages packet size is below 1500.

- We checked the communication issue with below command:

<pre>
# ping -W 2 -I <interface> -M do -s <pkt size> <IP address>
</pre>
