nfsd: Adjust nfs.conf setting/parsing of rdma port
|
|
|
d4362b |
|
|
|
d4362b |
The rpc.nfsd program can use option "--rdma" to enable
|
|
|
d4362b |
RDMA on the standard port (nfsrdma/20049) or "--rdma=port"
|
|
|
d4362b |
for an alternate port.
|
|
|
d4362b |
|
|
|
d4362b |
But now in /etc/nfs.conf, we need to specify the port
|
|
|
d4362b |
number (e.g. rdma=nfsrdma) to enable it, which is not
|
|
|
d4362b |
convenient.
|
|
|
d4362b |
The default setting "rdma=n" may cause more confusion.
|
|
|
d4362b |
|
|
|
d4362b |
Update to enable RDMA on standard port when setting
|
|
|
d4362b |
boolean YES to "rdma=". And using "rdma-port=" for an
|
|
|
d4362b |
alternate port if necessary.
|
|
|
d4362b |
|
|
|
d4362b |
Also let previous config (e.g. rdma=nfsrdma) work as well.
