Hi Marc -- Thanks for the help. I got past my rpm problems and am now much further along but have hit another roadblock. First, FYI, I am using a different approach then the RHEL5 OCFS2 Shared Root Mini Howto, because of the way that I want to use the shared root. Specifically, I am first building and booting a root ocfs2 filesystem, using my own kernel (2.6.29) and my own initrd.img. With this (and before I install any OSR stuff), I am able to boot it as a Xen paravirtualized guest, using the Xen kernel= and ramdisk= config options; the root disk is NOT an LVM because I don't need a /boot. The 2.6.29 kernel has CONFIG_IP_PNP and I pass in the IP address and hostname from the Xen config file. This all seems to work fine (for a single node). Next, I install the OSR rpms directly in the running ocfs2-root guest, then shut it down. Next, I mount the ocfs2-root-disk from another guest (that also has the OSR rpms installed) and follow the howto steps to create the cdsl infrastructure and links. Then I shut down the other guest. Next, I try to boot the OSR-modified ocfs2-root guest, but it has problems. It appears that /var doesn't exist as I get many messages such as: /etc/rc.d/rc.sysinit: /var/log/dmesg: No such file or directory and then the boot process seems to hang trying to start the System Logger. No, it just takes a very long time and eventually I get to a login prompt. (Or I can boot single-user mode and get the same error messages, but get to a bash prompt.) With a "ls -l /var", I see: lrwxrwxrwx 1 root root 14 <date> /var -> cdsl.local/var (Note no leading / before cdsl.local) but "ls -ld /cdsl.local" shows it is empty. Browsing around, I see that /cluster/cdsl is populated (with subdirectories 0 ... 7 and default) and each has an etc and a var subdirectory. /cluster/shared has a var subdirectory and a var/lib subdirectory. So I'm guessing that cdsl.local should somehow be linked to /cluster but isn't. True? One other thing I should mention... since my cluster.conf has 8 nodes numbered 0 to 7, in the "mount --bind" command during the cdsl setup steps, I used cluster/cdsl/0 instead of cluster/cdsl/1 to bind to cdsl.local. Any ideas? Maybe your initrd creates some necessary links and mine does not? (I tried booting with your initrd, but my ocfs2-root failed to mount giving a kernel panic... have you tested with linux-2.6.29? The error message "Heartbeat has to be started to mount a read-write clustered device" looks like it comes from a somewhat recent ocfs2 kernel patch I found here: http://www.mail-archive.com/ocf...@os.../msg00293.html and I worked around it by mounting with -o heartbeat=local) Sorry this is so long!
