| * ocfs2/cluster: Release debugfs file elapsed_time_in_msSunil Mushran2010-10-151-0/+1
| | | | | | | | | | | | An earlier commit forgot to remove a debugfs file, elapsed_time_in_ms. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Bump up dlm protocol to version 1.1Sunil Mushran2010-10-092-2/+2
| | | | | | | | | | | | | | | | | | dlm protocol 1.1. activates messages DLM_QUERY_REGION and DLM_QUERY_NODEINFO that are a must for global heartbeat. It also activates o2hb_global_heartbeat_active(). Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Show per region heartbeat elapsed timeSunil Mushran2010-10-061-0/+23
| | | | | | | | | | | | | | This patch adds a per region debugfs file that shows the elapsed time since the time the o2hb timer was last armed. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Add mlogs for heartbeat up/down eventsSunil Mushran2010-10-061-0/+4
| | | | | | | | | | | | This patch adds mlogs for o2hb up and down events. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Create debugfs dir/files for each regionSunil Mushran2010-10-061-0/+77
| | | | | | | | | | | | | | | | This patch creates debugfs directory for each o2hb region and creates files to expose the region number and the per region live node bitmap. This information will be useful in debugging cluster issues. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Create debugfs files for live, quorum and failed region bitmapsSunil Mushran2010-10-061-0/+63
| | | | | | | | | | | | | | This patch prints the bitmaps of live, quorum and failed regions. This information will be useful in debugging cluster issues. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Maintain bitmap of failed regionsSunil Mushran2010-10-071-0/+41
| | | | | | | | | | | | | | | | In global heartbeat mode, we track the bitmap of regions that have seen heartbeat timeouts. We fence if the number of such regions is greater than or equal to half the number of quorum regions. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Maintain bitmap of quorum regionsSunil Mushran2010-10-061-0/+35
| | | | | | | | | | | | | | | | o2hb allows online adding of regions. However, a newly added region is not used in quorum calculations unless it has been added on all nodes. This patch tracks a bitmap of such quorum regions. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Track bitmap of live heartbeat regionsSunil Mushran2010-10-061-1/+8
| | | | | | | | | | | | | | A heartbeat region becomes live (or active) after a fixed number of (steady) iterations. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Track number of global heartbeat regionsSunil Mushran2010-10-071-2/+22
| | | | | | | | | | | | | | | | In global heartbeat mode, we have a upper limit for the number of active regions. This patch adds the facility to track the number of active global heartbeat regions and fails to start heartbeat if the number exceeds the maximum. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2/cluster: Maintain live node bitmap per heartbeat regionSunil Mushran2010-10-061-0/+7
| | | | | | | | | | | | | | | | | | | | | | Currently we track a global livenode bitmap that keeps track of all nodes that are heartbeating in all regions. This patch adds the ability to track the livenode bitmap on a per region basis. We will use this facility in a later patch to allow us to withstand the loss of a minority number of regions.

| * ocfs2/cluster: Reorganize o2hb debugfs initSunil Mushran2010-10-071-23/+78

| | | | | | | | | | | | | | | | o2hb currently checks slots for configured nodes only. This patch makes it check the slots for the live nodes too to take care of a race in which a node is removed from the configuration but not from the live map.

| * ocfs2/dlm: Add message DLM_QUERY_NODEINFOSunil Mushran2010-10-072-1/+198
| | | | | | | | | | | | | | | | | | Adds new dlm message DLM_QUERY_NODEINFO that sends the attributes of all registered nodes. This message is sent if the negotiated dlm protocol is 1.1 or higher. If the information of the joining node does not match that of any existing nodes, the join domain request is rejected. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
| * ocfs2: Print message if user mounts without starting global heartbeatSunil Mushran2010-10-061-0/+2

| * ocfs2/dlm: Add message DLM_QUERY_REGIONSunil Mushran2010-10-093-1/+235
| | | | | | | | | | | | | | | | | | Adds new dlm message DLM_QUERY_REGION that sends the names of all active heartbeat regions. This message is only sent in the global heartbeat mode. If the regions in the joining node do not fully match the ones in the active nodes, the join domain request is rejected. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

| | | | | | | | | | | | | | | | | | | | Export function in o2hb to get a list of heartbeat regions. It also adds an upper limit to the length of the heartbeat region name. o2hb_global_heartbeat_active() currently disables global heartbeat. It will be enabled in a later patch after all the code is added. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

| * ocfs2: Add an incompat feature flag OCFS2_FEATURE_INCOMPAT_CLUSTERINFOSunil Mushran2010-10-093-9/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OCFS2_FEATURE_INCOMPAT_CLUSTERINFO allows us to use sb->s_cluster_info for both userspace and o2cb cluster stacks. It also allows us to extend cluster info to include stack flags. This patch also adds stackflags to sb->s_clusterinfo. It also introduces a clusterinfo flag OCFS2_CLUSTER_O2CB_GLOBAL_HEARTBEAT to denote the enabled global heartbeat mode. This incompat flag can be set/cleared using tunefs.ocfs2 --fs-features. The clusterinfo flag is set/cleared using tunefs.ocfs2 --update-cluster-stack. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 31c984a5acabea5d8c7224dc226453022be46f33 introduced a new syscall getdents64. However, in the syscall table, the new syscall still refers to the old getdents which doesn't work. The problem appeared with a system that uses the eglibc 2.12-r11187 (that utilizes that new syscall) is very confused. The fix has been tested with that eglibc version.

Originally it was introduced to describe a backing device which includes an unplug and congestion function and various bits of readahead information and VM-relevant flags. We're also using for tracking dirty inodes for writeback. To make writeback properly find all inodes we need to only access the per-filesystem backing_device pointed to by the superblock in ->s_bdi inside the writeback code, and not the instances pointeded to by inode->i_mapping->backing_dev which can be overriden by special devices or might not be set at all by some filesystems. Long term we should split out the writeback-relevant bits of struct backing_device_info (which includes more than the current bdi_writeback) and only point to it from the superblock while leaving the traditional backing device as a separate structure that can be overriden by devices. The one exception for now is the block device filesystem which really wants different writeback contexts for it's different (internal) inodes to handle the writeout more efficiently. For now we do this with a hack in fs-writeback.c because we're so late in the cycle, but in the future I plan to replace this with a superblock method that allows for multiple writeback contexts per filesystem.
