It is inconvenient for us to use MTU 9K for our gluster servers for various reasons. We typically have bonded 10G interfaces. We use distribute/replicate and gluster NFS for compute nodes. My understanding is the negative to using 1500 MTU is just less efficient use of the network. Are there other concerns? We don't currently have network saturation problems. We are trying to make a decision on if we need to do a bunch of extra work to switch to 9K MTU and if it is worth the benefit. Does the community have any suggestions? Erik

On the other side allow jumbo frames and change mtu on even hundreds on nodes is extremely simple, you can just test it. I don't see "bunch of extra work" here, just use ssh and some scripting or something like ansible...
