Tao, Thank you very much for your response. I figured out the problem - it was because (somehow) the file system was already mounted - DUH! So I have it up and running now.
Again, thank you for your time and assistance! -----Original Message----- From: Tao Ma [mailto:[EMAIL PROTECTED] Sent: Monday, June 30, 2008 9:35 PM To: Tina Soles Cc: V Srinivas; ocfs2-users@oss.oracle.com Subject: Re: [Ocfs2-users] Problems building ocfs2 rpm on Fedora 9 Hi Tina, AFAIK, if you can see the same device from both 2 nodes, you don't need to configure multipath(at least I never configure it when using ocfs2. ;) ) You mean you see the same UUID when execute 'echo "stats" | debugfs.ocfs2 -n /dev/sdb1' in 2 nodes, right? If yes, then the device should be ok. So could you please do like this: in node 2: 1. debugfs.ocfs2 -l DLM_DOMAIN SUPER JOURNAL allow this will open the debug message in ocfs2. 2. do mount and wait until it fails. 3. debugfs.ocfs2 -l DLM_DOMAIN SUPER JOURNAL off 4. paste the error dmesg here. Let us see what is going on there.
