When using the same system as nfs-server and nfs-client, and
|
|
|
d702dc |
using `nobind` option for autofs we would fall to the code where
|
|
|
d702dc |
we let `mount.nfs(8)` to handle the mount. However, when the
|
|
|
d702dc |
nfs-server and the nfs-client is the same system we end up calling
|
|
|
d702dc |
`rpc_ping` which gives negative return code. Due to this we fall to
|
|
|
d702dc |
the label next: and never attempt a mount of nfs share.
|
|
|
d702dc |
This patch fixes this BUG by not probing rpc_ping if we're
|
|
|
d702dc |
using rdma.
