2009-12-02ocfs2/cluster: Make fence method configurable - v2Sunil Mushran
By default, o2cb fences the box by calling emergency_restart(). 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@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
2008-06-16ocfs2: Move the hb_ctl_path sysctl into the stack glue.Joel Becker
ocfs2 needs to call out to the hb_ctl program at unmount for all cluster stacks. The first step is to move the hb_ctl_path sysctl out of the o2cb code and into the generic stack glue. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2007-07-10ocfs2: live heartbeat depends on the local node configurationJoel Becker
Removing the local node configuration out from underneath a running heartbeat is "bad". Provide an API in the ocfs2 nodemanager to request a configfs dependancy on the local node, then use it in heartbeat.

2007-07-10ocfs2: Depend on configfs heartbeat items.Joel Becker
ocfs2 mounts require a heartbeat region. Use the new configfs_depend_item() facility to actually depend on them so they can't go away from under us. First, teach cluster/nodemanager.c to depend an item on the o2cb subsystem. Then teach o2hb_register_callbacks to take a UUID and depend on the appropriate region. Finally, teach all users of o2hb to pass a UUID or NULL if they don't require a pin. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2007-02-14[PATCH] sysctl: register the ocfs2 sysctl numbersEric W. Biederman
ocfs2 was did not have the binary number it uses under CTL_FS registered in sysctl.h. Register it to avoid future conflicts, and change the name of the definition to be in line with the rest of the sysctl numbers. Signed-off-by: Eric W.

Allow configuration of OCFS2 timeouts from userspace via configfs Signed-off-by: Andrew Beekhof <abeekhof@suse.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-07[patch 1/3] OCFS2 - Expose struct o2nm_clusterAndrew Beekhof
Subsequent patches (namely userspace heartbeat and configurable timeouts) require access to the o2nm_cluster struct. This patch does the necessary shuffling. Signed-off-by: Andrew Beekhof <abeekhof@suse.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-01-03[PATCH] OCFS2: The Second Oracle Cluster FilesystemKurt Hackel
A simple node information service, filled and updated from userspace. The rest of the stack queries this service for simple node information. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com>
