Title: RE: [Oscar-users] Oscar installation with gigabit ethernet controllers

Hi Martin:

 

Unfortunately, OSCAR currently only supports one distribution at a time - so either you use Red Hat Linux 9 on all the nodes, or Red Hat Enterprise Linux 3.

 

I guess you have 2 choices:

 

1) Use network cards which are compatible with RHEL3

2) Use Red Hat Linux 9

 

If you are going to go back to Red Hat Linux 9, you may be better off using a newer distribution like Fedora Core 2 or 3, since we will no longer be supporting Red Hat Linux 9 for our next release.

 

Thanks,

 

Bernard

Well, I found out the problem. The SuperMicro X5DPA-GG is not compatible
with RedHat Linux Enterprise v3.

http://www.supermicro.com/support/resources/OS/E7501Compatibility.cfm

So I guess I have to use RedHat 9.0 on these nodes instead.

Would there be any problem if I use one OS (RH Enterprise 3) on one set of
nodes and another OS (RH 9) on the newer ones? Or should the cluster run
the same OS on all nodes?

Thanks again.
