Okay, so there are a few places where files are unconditionally closed,
regardless of whether or not they were open to begin with. The FSAL
would return ERR_FSAL_NOT_OPENED, but the caller would ignore the error,
since all it wanted to do was ensure the global FD was closed. Examples
of this are:
On remove
When we're recycling a handle
When a handle transitions from L1 to L2 of the LRU
My guess is that the last case is the one you're hitting. If the file
is in use, and very few handles are in use, then the handle will
transition back and forth across the L1/L2 border. Since you haven't
implemented open()/close() in your FSAL, the status() op can't tell the
handle was closed, so it might not open() again, if it thought it was
open already.

There was a read between open and first close.
Is this a known issue in that version of ganesha?

No, there should be a single close for each open. There may be
multiple opens, but only a single close for each open.
Which version of Ganesha?

When I write a lot of data to an NFS share using NFSv3 clients,
I see that Nfs-Ganesha opens file once but calls close on same
FD multiple times.
What is the reason behind that?
