Now I'm simply confused.
Do you mean one cachefile shared between the two nodes for this zpool? How, may
I ask, would this work?
Either that or a way for the nodes to update each others copy very
quickly. Such as a parallel filesystem.
It is the job of the cluster software to provide a mechanism to do that.
What I don't understand is how the second node is either a) supposed to share
the first nodes cachefile or b) create it's own without importing the pool.
Are you writing your own cluster framework ?
You say this is the job of the cluster software- does ha-cluster already handle
this with their ZFS modules?
Searching google for "solaris ha-cluster zfs zpool.cache" I found
this opensolaris.org thread on the ha-cluster list:
http://opensolaris.org/jive/thread.jspa?messageID=338413
That thread has information on which cluster release/patch is needed.
I've asked this question 5 different ways and I either still haven't gotten an
answer- or still don't understand the problem.
My apologies but I jumped in part way through the thread.
Are you writing your own cluster software or are you trying to use an
already existing cluster framework that already supports ZFS ?
