Dear all.
@work we are struggling with NFS server timeouts and subsequentially

The server timing out is a storage cluster with multiple IPs, served in
round-robin mode. Does autofs in cases of connectivity problems try to
resolve the server name multiple times - and then maybe get a "good" IP
- or is it "stuck" on the IP it get's when the initial mount request is
made?
If autofs does not re-resolve server names: Is there a way to provide
autofs with multiple names/ips which autofs tries all to find a possibly
working head node? How would this have to be configured?
I found the "Replicated Server" feature. How does autofs use the
different entries? Does it make a "round-robin" on it's own? And how
does autofs behave, if one of the multiple entries is not reachable or
the NFS server times out?
