    Problem Text

    The test is trying to force an ENOSPC error on the almost-full
    filesystem VSX_NOSPC_DEV. The test makes an arbitrary number of
    attempts to do so:

    (tset/PTHR.os/all/pwrite/pwrite_13.c)

    #define VSTH_PWRITE_TRIES 8192




    ...
    /* provide leniency due to filesystem behavior constraints */
    for ( cnt = 0; cnt < VSTH_PWRITE_TRIES; ++cnt )
    {
    offset = lseek( fd, (off_t) 0, SEEK_END );
    if ( offset != (off_t) -1 )
    {
    rval = pwrite( fd, (void *) &c, 1, offset );
    if (( rval == -1 ) && ( errno == ENOSPC ))
    {
    ...

    On some of our implementations, 8192 tries are not enough. The test
    passes if the value of VSTH_PWRITE_TRIES is increased:

    200|0 13 16:03:48|TP Start
    520|0 13 00005914 1 1|When there was no free space remaining on the device cont
    aining
    520|0 13 00005914 1 2|the file,
    520|0 13 00005914 1 3|then a call to pwrite(fildes, buf, nbytes, offset) will r
    eturn -1
    520|0 13 00005914 1 4|and set errno to ENOSPC.
    520|0 13 00005914 1 5|XCAE ref: Component PWRITE Assertion 13(A)
    520|0 13 00005917 4 1|pwrite failed on attempt 8442
    220|0 13 0 16:03:51|PASS
    410|0 13 1 16:03:51|IC End

    Since the value assigned to VSTH_PWRITE_TRIES is arbitrary and not
    derived from any standard, the test suite cannot make a conformance
    distinction based upon that value.
