Hi,
I'm trying to configure a HAST on FreeBSD, and suddenly it appears to be
a mind-breaking procedure. I totally don't get it, thus it doesn't work,
dumps cores and behaves weirdly. First of all, in an existing
configuration files paradigm, used widely in the whole IT industry, the
local view is usually described, and then remote mentioned. Here both
local and remote views are described and the configuration file (and
they aren't named explicitely local and remote since they are both
"remote"), like I understand the handbook article, must be _the_same_ on
both nodes. So, given that the sections are named arbitrarily, the local
hostname isn't mentioned or linked anywhere - how do I configure it
considering that I have _different_ GEOM providers of different machines ?
So, let's consider I have written this configutaion file:
resource hasta {
on gw0 {
local /dev/ada2p3
remote 192.168.0.247
}
on gw1 {
local /dev/ada0p4
remote 192.168.0.248
}
}
resource hastb {
on gw0 {
local /dev/ada3p3
remote 192.168.0.247
}
on gw1 {
local /dev/ada1p4
remote 192.168.0.248
}
}
The main question which IP do I mention where ? As far as I understand I
should mention "remote" IP in the "local" device block, and vice-versa,
but first of all - this doesn't work (dumps cores, complains bout FIFOs,
and so on ) - second of all - how the hastd itself finds who's local and
who's remote ? Thank god I have a GEOM configuration which cannot be
applied on both nodes, so only the correct node wouyld have the GEOM
provider mentions - otherwise I suggest this would corrupt my data and
make a total mess of it.
With thsi configuration file hastd doesn't work. "create" stage goes
smoothly, but then on one node (the one with /dev/ada1p4 and
/dev/ada0p4) hastd just loops crashing:
