...is setting up IPFailover as easy as Apple makes it out to be?
What's your experience?
For the second half of the equation, I'd like to have an Apple RAID
(14x750) set up with RAID-5 on both sides. They need to kept in
sync so when Xserve1 (which will be connected to the left side of
the RAID) dies, Xserver2 will grab the IP and chug along with the
right side of the RAID.
This means I need to sync both halves of the RAID. Apple mentions
rsync in their High Availability PDF, but from what I've read, this
part may not be reliable given rsync issues (dhan, feel free to
chime in! <G>). If rsync will work, would like to see some real
life examples of how people are keeping two volumes in sync...if
rsync isn't the answer, what is?
You don't normally architect things like this is HA systems but
instead use tiers that provide common services (file) to each member
of the coupled systems.
So the problem disappears if you use the right architecture.
