hi ya david
i see... now ya cheating a little bit...
nothing tricky eh ... as originally posted...
yes..amd supports the syntax for failovers...
autofs is supposed to be able to do so also in autofs-4
but i have not tested it autofs-4...
( dont know if it made it in )
vi /etc/auto.home
home -fstype=nfs,.... home1,home2,home3:/export/home
----
trick for above ( or any scenario where you have "same data" )
on multiple servers.... is to keep data in /export/home sync on
all 3 servers ... ( mirrored ... )
- if a server dies... the mirroring scheme wont help
as it'd need to play back all the missed transactions
while it was dead/sleeping/offline
----
you can also do (smart) round robin dns for automatic failovers...
and does NOT have to do all the "fancy stuff" in the automounter
