Hi guys, Forwarding this to the plug mailing list to get more help. My thread in the rocks-cluster list is getting a bit inactive. Hoping to get more results here.
Rocks 4.3 is a CentOS 4.4 based system. The compute nodes boot from the network and then get the kickstart file on the frontend. The system design was meant for large computing clusters so a pxeboot is a very scalable solution. I built a custom initrd.img for the script to be able to use the Realtek 8111B GigEthernet drivers. I downloaded the sources from the realtek website and plugged it into the build directory. I got this error message when i booted <F3> Terminal on slave node * ROCKS:getFileFromUrl:calling kickstartNetworkUp * ROCKS:rocksNetworkUp:no network devices in choose network device! <F4> Terminal on slave node <4> r8168: disagrees about version of symbol struct_module <4> r8168: disagrees about version of symbol struct_module It seems that the module is not loaded/ installed properly. the rocks-boot package uses the ddiskit module for creating initrd.img using a custom makefile different from the realtek source code. Based on reading Makefile logs, i was able to successfully build the r8168.ko module.

Our compute nodes uses a RTL8111B Gigabit ethernet controller. Its linux drivers can be downloaded from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false Then i followed the instructions in building a custom device driver from http://www.rocksclusters.org/rocks-documentation/4.3/customization-driver.html and created a "r8168" directory here are the files and some of its contents in the directory in rocks-4.3/src/roll/kernel/src/rocks-boot/enterprise/4/images/drivers : r8168/ r8168/r8168.mod.c r8168/r8168_n.c r8168/Makefile r8168/modinfo r8168/pcitable r8168/rtl_ioctl.c r8168/r8168.h r8168/rtl_ioctl.h r8168/LICENSE r8168/Makefile.build r8168/modules.dep [xxxxxxxxxxxxxxx drivers]$ cat r8168/modinfo r8168 net "RealTek RTL8168B/8111B and RTL8168C/8111C, Gigabit Ethernet controller" [xxxxxxxxxxxxxxx drivers]$ cat r8168/pcitable 0x10ec 0x8168 "r8168" "RealTek RTL8168B/8111B, RTL8168C/8111C Gigabit Ethernet controller" [xxxxxxxxxxxxxxx drivers]$ cat r8168/modules.dep [xxxxxxxxxxxxxxx drivers]$ head -n 15 r8168/Makefile MODULES := r8168 SOURCES := \ r8168.mod.c \ r8168_n.c HEADERS := \ r8168.h \ rtl_ioctl.h define MODULE_template I was able to successfully build the rocks-boot rpm using "make rpm" . I installed it as instructed and copied initrd.img and vmlinz to /tftpboot/pxelinux. The slave nodes were able to boot off via dhcp but I am having the following errors on the compute node when it installs the r8168 driver: (the F1 terminal gives me prompts since it was not able to obtain the kickstart files) <F3> Terminal on slave node * ROCKS:getFileFromUrl:calling kickstartNetworkUp * ROCKS:rocksNetworkUp:no network devices in choose network device! <F4> Terminal on slave node <4> r8168: disagrees about version of symbol struct_module <4> r8168: disagrees about version of symbol struct_module -- Allan M.
