[Ocfs2-users] kernel panic on redhat 5-7 x64

[Le Duy Phuong Nam]

Hi all,

 

I am using OCFS2-1.4.7 for 2 servers which is running Red hat enterprise 5.7
kernel 2.6.18-274.el5.

 

OCFS2 I use for drdb for replicating master-master. My 2 servers was
installed HA-Proxy.

 

Yesterday, server web1 was down with the log kernel panic. And today, web2
was down too. After that, I trace the log file on these server and found
that the reason from ocfs2.

 

The log like this:
