Re: amd

[Alvin Oga <aoga@Maggie.Linux-Consulting.com>]

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
