Pinned topic Flashes (Alerts): IBM Spectrum Scale (GPFS) running CES NFS service: possible undetected data corruption with NFS client using CES-based NFS service to store data

‏2019-04-02T13:36:45Z |


IBM has identified an issue in IBM Spectrum Scale when running CES-based NFS (a.k.a NFS Ganesha server) services, in which an application running on an NFS client may experience undetected data corruption. If the NFS Ganesha server starts file sync for processing a data commit request from NFS client and, at the same time, there is a "stripe group panic," or the mmfsd deamon is killed on the NFS Ganesha server, then data which was supposed to have been written to disk may be lost.
