I looked for PVFS_ENOSYS and its alias in the code, printed some stuff
and recompiled it... but I couldn't find anything.
Then I managed to use the strace as Sam Sampson suggested and found my
ENOSYS:
(...)
fcntl(4, F_SETLK, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = -1
ENOSYS (Function not implemented)
(...)
fcntl(5, F_SETLK, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = -1
ENOSYS (Function not implemented)
(...)
So, it seems that Rob Latham was right from the beginning.
You'll have to speak with your vendor to see if there are lock-free
alternatives. Despite "open" in the name "opencps" I cannot quickly see
where one would download and inspect the source.
