I received 6 replies. The conclution I made from them is to try it out on a
test configuration and then load it live if it works. I also put in a call
to Sun to see if this is an "Offical" supported configutation. And guess
what... It doesn't work and it is NOT a supported configuration! The 2
respondents who mentioned that the Prestoserv doesn't understand meta devices
created by DiskSuite are right on the money. What I don't understand is why
the documentation for either of these products doesn't say THAT!!!!!!!!
Especially when it is a KNOWN problem!
The presto command will tell you that it has a problem when you bring the
board up with the "presto -u" command. It returns the message...
presto: PRENABLE failed /dev/md1a: No such device
/dev/md1a is a meta device for 3 concatenated file systems. Not a very
accurate message since /dev/md1a does exist, but presto doesn't understand it.
Also if you do a "presto -l" to list all the file systems being acceletated,
/dev/md1a is NOT there.
Thanks to those who replied...
