My NFS client does not retry I/O.
Ganesha is reusing FD instead of opening file for every read request.
Sometimes it closes the fd even when there is a worker waiting still in
read() call on the same fd. As a result that worker returns read error and
ganesha drops the RPC. NFS client does not get any reply and it eventually
times out the I/O.
I see 2 solutions.
1. NFS client implement I/O retry
2. Ganesha open the file and try read again when file not opened error is
returned by FSAL.
3. Ganesha open the file for every read RPC instead of reusing FD.
NFS client is a legacy implementation and it is not going to be fixed.
Is there a way to achieve solutions 2 or 3?
