2006-09-25ocfs2: Allow binary names in the DLMMark Fasheh1-1/+2
The OCFS2 DLM uses strlen() to determine lock name length, which excludes the possibility of putting binary values in the name string. Fix this by requiring that string length be passed in as a parameter. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-30[PATCH] fs/ocfs2/dlm/dlmrecovery.c: make dlm_lockres_master_requery() staticAdrian Bunk1-2/+6
dlm_lockres_master_requery() became global without any external usage. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-28[PATCH] spin/rwlock init cleanupsIngo Molnar1-2/+2
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-27[PATCH] fs/ocfs2/dlm/: cleanupsAdrian Bunk1-1/+1
This patch #if 0's the no longer used dlm_dump_lock_resources(). Since this makes dlmdebug.h empty, this patch also removes this header. Additionally, the needlessly global dlm_is_node_recovered() is made static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-27ocfs2: move dlm work to a private work queueKurt Hackel1-2/+11
The work that is done can block for long periods of time and so is not appropriate for keventd. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-06-27ocfs2: dlm_remaster_locks() should never exit without completingKurt Hackel1-54/+62
We cannot restart recovery. Once we begin to recover a node, keep the state of the recovery intact and follow through, regardless of any other node deaths that may occur. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-27ocfs2: special case recovery lock in dlmlock_remote()Kurt Hackel1-0/+4
If the previous master of the recovery lock dies, let calc_usage take it down completely and let the caller completely redo the dlmlock() call. Otherwise, there will never be an opportunity to re-master the lockres and recovery wont be able to progress.

2006-03-25[PATCH] ocfs2: dlm recovery fixesKurt Hackel1-17/+21
when starting lock mastery (excepting the recovery lock) wait on any nodes needing recovery. fix one instance where lock resources were left attached to the recovery list after recovery completed. ensure that the node_down code is run uniformly regardless of which node found the dead node first.

2006-03-01[PATCH] ocfs2: use hlists for lockres hashMark Fasheh1-11/+12
Switch from list_head to hlist_head. Make the size of the hash dependent upon the allocated area, rather than a constant. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-02-16[PATCH] ocfs2: add dlm_wait_for_node_deathKurt Hackel1-0/+18
* add dlm_wait_for_node_death function to be used after receiving a network error. this will wait for the given timeout to allow the heartbeat callbacks to update the domain map. without this, some paths may spin and consume enough cpu that the heartbeat gets starved and never updates.

2006-02-16[PATCH] ocfs2: recheck recovery state after getting lockKurt Hackel1-0/+24

fs/ocfs2/dlm/dlmrecovery.c does now use msleep(), and does therefore need to #include <linux/delay.h> for getting the prototype of this function. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* fix a hang which can occur during shutdown migration * do not allow nodes to join during recovery * when restarting lock mastery, do not ignore nodes which come up * more than one node could become recovery master, fix this * sleep to allow some time for heartbeat state to catch up to network * extra debug info for bad recovery state problems * make DLM_RECO_NODE_DATA_DONE a valid state for non-master recovery nodes * prune all locks from dead nodes on $RECOVERY lock resources * do NOT automatically add new nodes to mle nodemaps until they have properly joined the domain * make sure dlm_pick_recovery_master only exits when all nodes have synced * properly handle dlmunlock errors in dlm_pick_recovery_master * do not propagate network errors in dlm_send_begin_reco_message * dead nodes were not being put in the recovery map sometimes, fix this * dlmunlock was failing to clear the unlock actions on DLM_DENIED Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-01-03[PATCH] OCFS2: The Second Oracle Cluster FilesystemKurt Hackel1-0/+2132
A distributed lock manager built with the cluster file system use case in mind. The OCFS2 dlm exposes a VMS style API, though things have been simplified internally. The only lock levels implemented currently are NLMODE, PRMODE and EXMODE. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com>
