HOWTO Install OpenGFS for IEEE1394 (Firewire) Devices I have gotten this to work with the ADS Pyro Firewire Drive (it has the Oxford ieee1394-->IDE chipset) box. If you have other success stories let me
know. Detailed steps for Firewire shared storage: 1. Get the source, either from CVS or via tarball (some releases are also available as source RPMs). Copy to each computer in the cluster. A. Retrieve (check out) the OpenGFS source from CVS: export CVSROOT=:pserver:email@example.com:/cvsroot/opengfs cvs login (just hit "enter" key for the password) cvs -z3 co opengfs (-z3 invokes compression, if desired) HINT: Any subsequent updates of the code can use "cvs up opengfs". *OR* B. Download a tarball from http://opengfs.sourceforge.net. Click on "Download". Tarballs come in two varieties: 1) Releases (click on "Sourceforge Download Page"), and 2) Nightly CVS tarballs (click on "Nightly CVS Tarball"). For Release tarballs: tar -xvzf opengfs-n.n.n.tar.gz (substitute version for n.n.n) For Nightly tarballs: tar -xvzf opengfs-cvsroot.tar.gz If you are having trouble with the ieee1394 drivers you will probably need to download the ieee1394 drivers from http://www.linux1394.org Just follow the directions on that site to install them. 2. Patch/Rebuild Kernel Change to your kernel source directory and apply the kernel patches for ogfs and ieee1394 (sbp2-reset.patch, you need this patch even if you got the ieee1394 drivers from http://www.linux1394.org), then rebuild your kernel (make sure you enable the ieee1394 drivers). NOTE: It is now (for CVS code since July 30, 2003, and any releases after that) a *requirement* that patches for the DM device manager are applied to your 2.4.x kernel! See step 2 in HOWTO-nopool. 3. Insert ieee1394 Modules If you compiled the ieee1394 drivers as modules do a: modprobe ohci1394 modprobe sbp2 sbp2_exclusive_login=0 Now you should be able to mount the ieee1394 drive between each computer, but not at the same time. Check for success: cat /proc/partitions shows shared drive(s) HINT: You may have to rmmod sbp2 and reload it to get it to list the drive in /proc/partitions , but I think loading the ohci1394 driver first should take care of the problem I was having. OR You can use the rescan-scsi-bus.sh script from the kernel_patches/ieee1394 directory 4. Progress Report At this point you should be running a kernel patched with the OpenGFS patches and the ieee1394 patches. 5.
