Rolling upgrade from earlier version to InfoScale 7.4.2 may fail for LLT over UDP configuration in FSS environment (3981917)
In a Flexible Storage Sharing (FSS) environment where LLT is configured over UDP, the rolling upgrade of InfoScale from earlier version to 7.4.2 may fail. The failure may occur if the NIC MTU is set to 9000 and the value of the MTU field in the /etc/llttab file is set to - (dash). Due to the mismatch in the MTU values, the remote I/Os initiated by the VxVM layer may get stuck and the upgraded node remains in Joining state.
Workaround:
In an FSS environment where LLT is configured over UDP, before you perform a rolling upgrade from an earlier InfoScale version to 7.4.2, ensure that the MTU value in the /etc/llttab
file is set to 1500 instead of a - (dash).
That is, instead of setting the value as dash as:
link eth1 udp - udp 50000 - 192.168.10.1 -
Set the MTU value to 1500 manually:
link eth1 udp - udp 50000 1500 192.168.10.1 -
