SUSE Linux Enterprise Server 15 SP1
There could be many causes for such a symptom. This document only covers one possible cause. This particular problem only occurs if the network interface has scatter-gather turned off, which is not common. This setting can be checked with:
ethtool -k eth0 | grep scatter
This did not occur on SLES 12 SP4.
Can't mount NFS over IPv6.
For SLES 12 SP5, depending on your kernel flavor:
For SLES 15 SP1, depending on your kernel flavor:
An alternative to updating the kernel is to insure scatter-gather is on, for the network interface used for the communication in question. This can be accomplished on-the-fly with the command:
ethtool -K eth0 sg on
(Where "eth0" may need to be replaced with the actual name of the interface in question.)
To create a "permanent" setting that comes into effect during boot, edit /etc/sysconfig/network/ifcfg-eth0
ETHTOOL_OPTIONS='-K eth0 sg on'
Where "eth0" (in both the file name and the setting) may need to be replaced with the actual name of the interface in question.
