Apparent filesystem corruption on zFCP connected volumes
This document (3766948) is provided subject to the disclaimer at the end of this document.
A filesystem or a mirrored device mapper volumes appears to be corrupt on each boot, even though the system was shut down correctly previously. Accessing the volume may also show performance issues or the filesystem going read-only.
Some zFCP adapters do not implement QDIO modes for FCP correctly. As a workaround, turning off QIOASSIST with #CP SET QIOASSIST OFF for the affected z/VM guests avoids the apparent filesystem corruption.
