| * | ocfs2/dlm: dlm_is_lockres_migrateable() returns booleanSunil Mushran2011-05-232-84/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | Patch cleans up the gunk added by commit 388c4bcb4e63e88fb1f312a2f5f9eb2623afcf5b. dlm_is_lockres_migrateable() now returns 1 if lockresource is deemed migrateable and 0 if not.

| * ocfs2: add cleancache supportDan Magenheimer2011-05-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This eighth patch of eight in this cleancache series "opts-in" cleancache for ocfs2. Clustered filesystems must explicitly enable cleancache by calling cleancache_init_shared_fs anytime an instance of the filesystem is mounted. Ocfs2 is currently the only user of the clustered filesystem interface but nevertheless, the cleancache hooks in the VFS layer are sufficient for ocfs2 including the matching cleancache_flush_fs hook which must be called on unmount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | During resource migration, if the target node were to die, the thread doing the migration spins until the target node is not removed from the domain map.

* | | ocfs2/cluster: Increase the live threshold for global heartbeatSunil Mushran2011-05-131-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen isolated cases (very few, I might add) of o2hb not detecting all live nodes on startup. One plausible reasoning for it is that other node had a hb io delay at the same time. The live threshold set at 2 (as low as it can be) could be increased to ameliorate the situation. But increasing the threshold directly affects mount time. Currently it takes around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing the threshold will make mounts even slower. As the issue itself is rare, we have left things as they are for the local heartbeat mode. However we can improve the situation for global heartbeat mode as in that mode, we start the heartbeat much before the mount. This patch doubles the live threshold for the start of the first region in global heartbeat mode. Addresses internal Oracle bug#10635585.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes a bug in the o2dlm protocol negotiation in that it is using the builtin version rather than the negotiated version during the domain join. This causes join errors when a node having kernel >= 2.6.37 joins a cluster with nodes having kernels < 2.6.37. This only affects the o2cb cluster stack.

* | | ocfs2: skip existing hole when removing the last extent_rec in punching-hole ↵Tristan Ye2011-05-131-0/+12

In the case of removing a partial extent record which covers a hole, current punching-hole logic will try to remove more than the length of whole extent record, which leads to the failure of following assert(fs/ocfs2/alloc.c): 5507 BUG_ON(cpos < le32_to_cpu(rec->e_cpos) || trunc_range > rec_range); This patch tries to skip existing hole at the last attempt of removing a partial extent record, what's more, it also adds some necessary comments for better understanding of punching-hole codes.
