Master node in an FSS cluster may panic or behave unexpectedly if ‘vol_taskship’ is set to 1 (4003796)

Task shipping is an internal feature that enhances the performance of a Flexible Storage Sharing (FSS) cluster and manages the data exchanges between the cluster nodes. This feature is enabled when the vol_taskship tunable is set to 1. While this feature is enabled, any mismatch in the data sizes can lead to an unexpected behaviour of the master node, for example, the system may panic.

Workaround:

Before using an FSS cluster, disable the task shipping feature by setting the value of the vol_taskship tunable to 0. You may also want to perform this workaround while upgrading an FSS cluster.
