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.
