Background - I used to work for Sun's CPRE and PTS support
organisations, getting customers back on their feet after
large scale disasters in the storage area.
Here's where I start to take a hard line about configs.
If your 4 hosts are db servers, dumping ~1Tb per night
and you cannot afford either:
- sufficient space for them to have their own large luns, or
- a dedicated GigE network for dumping that data,
then you need to make an investment in your business and
do is very soon. That would either be purchasing QFS, and/
or purchasing extra space for your array.
You haven't - as far as I can see - explained why you must
have each of these hosts being able to read and write that
data in a shared configuration.
Perhaps if you explain what you are really trying to
achieve we could help you more appropriately.
