I've added the option (just like you have it below) as the last line in the file, OSCAR nodes couldn't image any more. Checking the oscarmaster script shows that when the /dev/shm option is added to the .disk file, SIS tries to install to the second physical hard drive. I think that is the same problem Paul had.
To me, that is a real bug. If I need to add devices to the .disk file, OSCAR needs to interpret them in the correct order. I've solved the /dev/shm issue by dropping a post-install script in the appropriate bin. As I've brought up before, /dev/shm should added to standard OSCAR installs, as it's standard on RHEL installs. There are several cluster applications (some I can't tell you about yet) that use this device.

There are several ways to customize the partition table one wants on the nodes and I consider it normal that you change the partitioning for your nodes if you don't like the default. The method described in my previous email is (IMO) the best one, it gives you full control over what will happen. Alternatively: - copy the disktab file you want to adapt from /opt/oscar/oscarsamples/*.disk - edit it, i.e. in your case add a line like none - tmpfs /dev/shm defaults - select the edited disktable file when building your preferred image I hope this helps. regards, Erich On Thursday 12 January 2006 06:21, Paul Greidanus wrote: > Hi Erich, (and everyone else) > > I'm just wondering if anyone's working on this one?
