Hi,
I know you're busy with testing OSCAR 4.1 but maybe you want to have a
look at mksiadapter http://home.arcor.de/efocht/oscar/mksiadapter .
When setting up clusters with multiple ethernet or IP-like adapters
(like myrinet over IP or IBoIP) I usually did it by modifying the
autoinstall script manually before the installation. It's not really
nice... Now there's a better way to do it:
Use mksiadapter to define the additional adapters in your cluster. For
example:
mksiadapter --Add --name $node --ipaddr $myriip --netmask $netmask --devname
myri0
Usage: mksiadapter [ operation ] <options>
operation
-A, --Add add an adapter to machine
-D, --Delete delete adapter from machine
-U, --Update update adapter info for machine
-L, --List list all adapters for machine
options
--name <name> machine name.
--all apply to all adapters (valid for --Delete)
--ipaddress <address> the IP address of the adapter.
--MACaddress <MACaddress> the MAC address of the adapter.
--devname <devname> the adapter device name (default: sometimes eth0)
--netmask <mask> the netmask for the interface (default,
255.255.255.0)
-v, --verbose massive verbose output
--parse print colon-delimited output (valid with --List)
This is derived from mksimachine and similar in use.
Call "sis_reload network" on all nodes. (Details to this in a later
email).
One additional patch to systeminstaller is required:
http://home.arcor.de/efocht/oscar/sin-multiadapter.patch
This changes the synchosts subroutine in SystemInstaller::Machine to
consider only the "eth0" adapters for the IP -> hostname assignment in
/etc/hosts. If you don't apply this your /etc/hosts will contain the
last adapter IP for the cluster hosts. This is not what one usually
wants.
Regards,
Erich
