Hi Daniel, Thanks for your prompt reply. I'm trying to implement the lock_op2 fct , we have a FS supporting lock owner basing on the host IP & pid of the program on the host (and also the file & ranges). That's why while converting from the Ganesha lock to FSAL lock, I need to find something to simulate the PID. Can you advice?

I don't believe there's any necessity for a client to send different client_id's for different processes, as long as it can tell locally which lock is which. So a server cannot depend on these being different to do things.
What exactly are you trying to achieve here? What's the problem being solved?

Hi Daniel,
Thank you for your reply. I've also tried with the client_id but it also has the same value for 2 different processes. So if the client_id and the opaque always have the same value (for 2 different processes), how can we distinguish the client?
I've tried with this field
so_owner.so_nfs4_owner.so_clientid
Thank you. Viet

The client program ID in a lock owner is an opaque. That is, it's not defined in the spec, and the server can't use it for anything other than a byte string. The concatenation of the client-ID and the opaque part of the lock owner is unique, but the opaque part of the lock owner itself is not.
That value only has meaning to the client.

Hello,
While trying to get more information related to the lock owner, I'm trying to get the client program id and realize that it always takes the same value (easy to do with a test program forking another process, parent lock a file range then the child locks another range). Is it something similar to the client process id that is stored in the client record structure? or any other suggestions?
Thank you
