What version of Ganesha are you using? V2.8.x now restricts which symbols from being
exported by the nfs-ganesha .so, so if that’s the version you are using, that COULD be a
problem.

The most common reason I've seen for a new fsal not to load would be if it has
undefined symbols or otherwise can't be loaded. If you think it's not being
loaded, you could set a gdb breakpoint on dlopen() and step through it. I'd suggest
you start with fixing your logging configuration, there is detailed information about
fsals being loaded that I'd look for first.

Do you have following lines in main.c of your FSAL?

dear devel
Very sorry to trouble you！I think I have checked it according to you, but I still
don't know the cause of the problem。I feel very depressed because of having wasted
several days on this issue。I changed the name of module from NCSF to NCDFS。Please tell me
where my mistake is and thank you very much!
ganesha.conf
The log of problem are the same as before！
I am looking forward to hearing from you. Thank you very much!

You will generally get a faster response by posting to the mailing list

contributors directly.
FSALs are loaded by the fsal_manager in fsal_load.c. The library that is loaded is
<libdir>/ganesha/lib<fsal>.so where <fsal> is the Name given in the
config for that FSAL, transformed to lower case. You will need to make sure there are 3
things done correctly:
1. The name of your fsal library must match the name given in the config
2. Your fsal must be installed in the correct location
3. Your fsal must have MODULE_INIT and MODULE_FINI functions built into it.
Without seeing the source, it's a bit hard to debug.
