[Ocfs2-users] ocfs2/o2cb problem with openais/pacemaker

[Patrick J. LoPresti]

Hi, Juergen.  I found your message from back in April while
researching the same issue.

Using "strace" on ocfs2_controld.pcmk, I discovered the problem:
/dev/misc/ocfs2_control does not exist.  (It might be nice if the
error message simply said that...)

To fix this, I created a file /etc/udev/rules.d/99-ocfs2_control.rules
containing the following single line:

KERNEL=="ocfs2_control", NAME="misc/ocfs2_control", MODE="0660"


I am not sure whether Debian already has a udev .rules file for doing
this, or if so, which package it is in (or should be in).

P.S.  The latest redhat-cluster (dlm etc.) and ocfs2-tools (plus
ocfs2-tools-pacemaker) in Debian experimental now include support for
Pacemaker.
