...ed to add it (but i did'nt find a way to flip the fs in RO). Here is a proposal for this functionnality, based on ocfs2-1.4.7. This patch add an entry 'fence_cmd' in /sys to specify an userspace fence script. This behavior can be selected by echoing the new keyword 'cmd' in fence_method. Example : echo "/usr/local/sbin/my_fencer"> /sys/kernel/config/cluster/ocfs2/fence_cmd echo "cmd"> /sys/kernel/config/cluster/ocfs2/fence_method Hope this could interest someone.

...While this scheme works well in production, it comes in the way during testing as it does not let the tester take stack/core dumps for analysis. This patch allows user to dynamically change the fence method to panic() by: # echo "panic" > /sys/kernel/config/cluster/<clustername>/fence_method Signed-off-by: Sunil Mushran <sunil.mushran at oracle.com> --- fs/ocfs2/cluster/nodemanager.c | 50 ++++++++++++++++++++++++++++++++++++++++ fs/ocfs2/cluster/nodemanager.h | 7 +++++ fs/ocfs2/cluster/quorum.c | 14 +++++++++- 3 files changed, 69 insertions(+), 2 deletions(-) di...

...nics. So unless you want the same, our recommendation would be for you to leave the fence method as-is. Do note that the fence method of a node can be toggled between "reset" and "panic" at anytime. To view the current fence method, do: # cat /sys/kernel/config/cluster/CLUSTER/fence_method reset To change to panic, do: # echo panic > /sys/kernel/config/CLUSTER/cacl10/fence_method # cat /sys/kernel/config/cluster/CLUSTER/fence_method panic The bug fixes can be classified under three groupings. The first group involves cluster locking. Specifically in the area of downconver...

Hi, I have a 2 nodes ocfs2 cluster running UEK 2.6.32-100.0.19.el5, ocfs2console-1.6.3-2.el5, ocfs2-tools-1.6.3-2.el5. My problem is that all the time when i try to run /etc/init.d/o2cb stop it fails with this error: Stopping O2CB cluster CLUSTER: Failed Unable to stop cluster as heartbeat region still active There is no active mount point. I tried to manually stop the heartdbeat with

Hi, everyone I have some questions with the OCFS2 when using it as vm-store. With Ubuntu 1204, kernel version is 3.2.40, and ocfs2-tools version is 1.6.4. As the network configure change, there are some issues as the log below. Why is there the information of "Node 255 (he) is the Recovery Master for the dead node 255" in the syslog? Why the host ZHJD-VM6 is blocked until it reboot
