It is perfectly okay to create a number of journals greater or equal to the number of nodes. So 3 and 4 are both okay. Second, if you created the volume group without clvmd running, you may have created it without the clustered bit set. You may need to do this command: vgchange -cy /dev/your_vg Third, GFS does not reboot the system. The system is most likely being fenced due to a problem discovered by the cluster infrastructure. That problem might be GFS's fault, but we have no way to know. Fourth, if your file system is shared between nodes, you probably want to use a shared file system. Using ext3 will only work properly if the file system is only mounted by a single computer. If it's mounted by more than one computer, use GFS or GFS2. Fifth, to debug the problem please send the console messages to this mailing list so we can tell more about the symptoms. I hope this helps.
