Issues related to LLT

This section covers the known issues related to LLT in this release.

LLT port stats sometimes shows recvcnt larger than recvbytes

With each received packet, LLT increments the following variables:

■ recvcnt (increment by one for every packet)

■ recvbytes (increment by size of packet for every packet)

Both these variables are integers. With constant traffic, recvbytes hits and rolls

over MAX_INT quickly. This can cause the value of recvbytes to be less than the

value of recvcnt. [1788315]

This does not impact the LLT functionality.

LLT may incorrectly declare port-level connection for nodes in large cluster

configurations

When ports get registered and unregistered frequently on the nodes of the cluster,

LLT may declare that a port-level connection exists with another peer node. This

occurs in some corner cases even though a port is not even registered on the peer

node. [1809827]

Issues related to I/O fencing

This section covers the known issues related to I/O fencing in this release.

All nodes in a sub-cluster panic if the node that races for I/O fencing panics

At the time of a network partition the lowest node in each sub-cluster races for

the coordination points on behalf of that sub-cluster. If the lowest node is unable

to contact a majority of the coordination points or the lowest node itself

unexpectedly panics during the race, then all the nodes in that sub-cluster will

panic. [1965954]
