Re: [Ocfs2-users] one node kernel panic
uek is a different kernel entirely. It is hard to say whether you
will or will not hit it with uek mainly because the underlying code
is different.

Re: [Ocfs2-users] one node kernel panic
Thank you for responding.
I think UEK5 is based on RHEL5 kernel.
Does the problem same as UEK5 arise?

Re: [Ocfs2-users] one node kernel panic
int sigprocmask(int how, sigset_t *set, sigset_t *oldset)
{
int error;
spin_lock_irq(¤t->sighand->siglock); < CRASH
if (oldset)
*oldset = current->blocked;
...
}
current->sighand is NULL. So definitely a race. Generic kernel issue.
Ping your kernel vendor.

[Ocfs2-users] one node kernel panic
Hi, I run ocfs2/drbd active-active 2node cluster. ocfs2 version is 1.4.7-1 ocfs2-tool version is 1.4.4 Linux version is RHEL 5.4 (2.6.18-164.el5 x86_64) 1 node crash with kernel panic once. What is the cause? The bottom is the analysis of vmcore.
