[Ocfs2-users] Problems building ocfs2 rpm on Fedora 9

Tue Jul 1 04:59:28 PDT 2008

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!

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.

Regards,
Tao
