2006-08-07ocfs2: allocation hintsMark Fasheh4-13/+145
Record the most recently used allocation group on the allocation context, so that subsequent allocations can attempt to optimize for contiguousness. Local alloc especially should benefit from this as the current chain search tends to let it spew across the disk. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-08-07ocfs2: better group descriptor consistency checksMark Fasheh1-20/+94
Try to catch corrupted group descriptors with some stronger checks placed in a couple of strategic locations. Detect a failed resizefs and refuse to allocate past what bitmap i_clusters allows. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-08-07ocfs2: limit cluster bitmap information saved at mountMark Fasheh2-3/+6
We were storing cluster count on the ocfs2_super structure, but never actually using it so remove that. Also, we don't want to populate the uptodate cache with the unlocked block read - it is technically safe as is, but we should change it for correctness. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-08-07[PATCH] fs/ocfs2/dlm/dlmmaster.c: unexport dlm_migrate_lockresAdrian Bunk1-1/+0

2006-08-07ocfs2: fix check for locally granted state during dlmunlock()Kurt Hackel1-1/+1
If a process requests a lock cancel but the lock has been remotely granted already then there is no need to send the cancel message. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-08-07ocfs2: do not modify lksb->status in the unlock astKurt Hackel1-25/+12
This can race with other ast notification, which can cause bad status values to propagate into the unlock ast. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-08-07ocfs2: Fix lvb corruptionKurt Hackel1-0/+6

2006-06-29ocfs2: clean up some osb fieldsMark Fasheh4-42/+4
Get rid of osb->uuid, osb->proc_sub_dir, and osb->osb_id. Those fields were unused, or could easily be removed. As a result, we also no longer need MAX_OSB_ID or ocfs2_globals_lock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-29ocfs2: fix init of uuid_net_keyMark Fasheh1-1/+1

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>

Print a warning to the user when a node with a different dead count joins the region. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-29ocfs2: Compile-time disabling of ocfs2 debugging output.Joel Becker3-7/+25
Give gcc the chance to compile out the debug logging code in ocfs2. This saves some size at the expense of being able to debug the code. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar7-8/+8
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>
2006-06-26[PATCH] fs/ocfs2/dlm/: cleanupsAdrian Bunk5-35/+3
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>

2006-06-26ocfs2: retry operations when a lock is marked in recoveryKurt Hackel1-0/+20
Before checking for a nonexistent lock, make sure the lockres is not marked RECOVERING. The caller will just retry and the state should be fixed up when recovery completes. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-06-26ocfs2: 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>
2006-06-26ocfs2: special case recovery lock in dlmlock_remote()Kurt Hackel2-10/+27
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. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-26ocfs2: pending mastery asserts and migrations should block each otherKurt Hackel1-0/+21
Use the existing structure for blocking migrations when ASTs are pending to achieve the same result. If we can catch the assert before it goes on the wire, just cancel it and let the migration continue.

2006-06-26ocfs2: temporarily disable automatic lock migrationKurt Hackel2-5/+23
Now we never change the owner of a lock resource until unmount or node death. This will be re-enabled once some issues in the algorithm used have been resolved. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-26ocfs2: do not unconditionally purge the lockres in dlmlock_remote()Kurt Hackel1-1/+7
In dlmlock_remote(), do not call purge_lockres until the lock resource actually changes. otherwise, the mastery info on the lockres will go away underneath the caller. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-26ocfs2: increase backoff before waiting for recoveryKurt Hackel1-1/+1
When mastering non-recovery lock resources, additional time was frequently needed to allow the disk heartbeat to catch up with the network timeout. the recovery lock resource is time critical and avoids this path.

2006-06-26ocfs2: have dlm_pre_master_reco_lockres() ignore dead nodesKurt Hackel1-0/+1
