Ian Kent 2017-01-10 10:38:00 UTC Doc Text The availability probe isn't done for anything autofs thinks is a local mount because it's the local machine.

It first tries a bind mount and that fails it falls back to trying a local NFS mount. But if the local NFS server is not running mount.nfs(8) can suffer a lengthy timeout.

Work around this by checking if an NFS server on the local machine is responding before trying the mount.

Ian Kent 2017-03-16 05:27:47 UTC Doc Text The availability probe isn't done for anything autofs thinks is a local mount because it's the local machine.

It first tries a bind mount and that fails it falls back to trying a local NFS mount. But if the local NFS server is not running mount.nfs(8) can suffer a lengthy timeout.

Work around this by checking if an NFS server on the local machine is responding before trying the mount.
Cause:
A server availability probe is not done for mount requests that autofs thinks are local because a bind mount on the local machine should be able to be used. If the bind mount fails an NFS mount on the local machine then tried.

Consequence:
But if the NFS server is not running on the local machine the mount attempt can suffer a lengthy time out before failing.

Fix:
To resolve this an availability probe has been added to the case where a bind mount is first tried but fails and autofs falls back to trying to use an NFS server on the local machine.

Result:
If a bind mount on the local machine fails the fall back to trying an NFS mount on the local machine fails quickly if the local NFS server is not running.
