I finally got the cycles to take a look at these... My apologies for
taking so long...
So I went ahead took a look... Clean them up a bit. There were a couple
typos and they did not apply cleanly to my tree... While I was
doing this I got this gnawing feeling that we probably should have
some type of global configuration file where all these command
line variables can be set.
It would have to be distro friendly meaning the same place in all
distros... Maybe something like /etc/nfsclient.conf patterned off
the /etc/nfsmount.conf config file??
So I'm thinking it does make sense to have a way to set
all these but I'm just not keen on how they are being set.
IDK... Maybe I'm over thinking it.. :-)
Finally, during my testing the only flags that seem to work
was the statd ones:
# rpc.nfsd --rdma 8
rpc.nfsd: Unable to request RDMA services: Protocol not supported
# rpc.nfsd --grace-time 66
rpc.nfsd: Unable to set /proc/fs/nfsd/nfsv4gracetime: Device or resource busy
# rpc.nfsd --lease-time 66
rpc.nfsd: Unable to set /proc/fs/nfsd/nfsv4leasetime: Device or resource busy
Is this expected?
