GPFS is 'IBM General Parallel File System', also called
'IBM Spectrum Scale', stalls when a process issues a lot
of fsyncs in a short timeframe.
It is better if the VM I/O is not synchronous.
It is racommended to use writeback caching policy.
In order to permit that it is added VIR_FILE_SHFS_GPFS to
the list of shared file systems in virStorageFileIsClusterFS
function.
