<div>Hello,</div><div><br></div><div> I wasn't using the synctask_new worker, but now I implemented my code using it to trigger the create/write call. Btw, is the usage of syncop calls documented somewhere? I found it through the history of the dev-list.<div>
<br></div><div> But going ahead on my issue, I was able to create the file avoiding the NFS stale handle error. The file is being created at the backend, but the syncop_create call it's still returning an error from the posix translator at the server side. I copied the error from the glusterd log below... I am checking the code trying to figure it out.</div>
<div><br></div><div> To write the file I am generating a new gfid for the local file and setting the pargfid as 1 (root node) with the loc.parent pointing to the inode->table->root inode. Below I copied what is being copied the loc, fd, flag and mode_t structures being used at the create call. </div>

You can check how fuse-bridge, nfs, api/src/glfs.c are all setting gfid-req. In your case you would want to copy the GFID of the original file for the cached file as well.</div>
