Are you doing this for EC/disperse volume?

Hi,
        Hole punching through fallocate succeeds for a ext4 mount path. But it fails for a glusterfs mount path. The volume is a disperse volume.

        fallocate(fd,FALLOC_FL_PUNCH_HOLE|FALLOC_FL_KEEP_SIZE,0,sizeof(array)) fails with a return code of EOPNOTSUPP.

       The ext4 file system mount arguments are “rw,noexec,nosuid,nodev,user_xattr,discard”.

Thanks and Regards,
Ram
