* GFS2: Send useful information with uevent messagesSteven Whitehouse2009-01-05
| | | | | | | | | | | | | | | | | | | | | | In order to distinguish between two differing uevent messages and to avoid using the (racy) method of reading status from sysfs in future, this adds some status information to our uevent messages. Btw, before anybody says "sysfs isn't racy", I'm aware of that, but the way that GFS2 was using it (send an ambiugous uevent and then expect the receiver to read sysfs to find out the status of the reported operation) was. The additional benefit of using the new interface is that it should be possible for a node to recover multiple journals at the same time, since there is no longer any confusion as to which journal the status belongs to. At some future stage, when all the userland programs have been converted, I intend to remove the old interface. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* dlm: allow multiple lockspace createsDavid Teigland2008-08-28
| | | | | | | | | | Add a count for lockspace create and release so that create can be called multiple times to use the lockspace from different places. Also add the new flag DLM_LSFL_NEWEXCL to create a lockspace with the previous behavior of returning -EEXIST if the lockspace already exists. Signed-off-by: David Teigland <teigland@redhat.com>

* [GFS2] Remove all_list from lock_dlmSteven Whitehouse2008-06-27
| | | | | | | | | | | I discovered that we had a list onto which every lock_dlm lock was being put. Its only function was to discover whether we'd got any locks left after umount. Since there was already a counter for that purpose as well, I removed the list. The saving is sizeof(struct list_head) per glock - well worth having.

* [GFS2] Remove remote lock dropping codeSteven Whitehouse2008-06-27
| | | | | | | | | | | | | | | | | | | There are several reasons why this is undesirable: 1. It never happens during normal operation anyway 2. If it does happen it causes performance to be very, very poor 3. It isn't likely to solve the original problem (memory shortage on remote DLM node) it was supposed to solve 4. It uses a bunch of arbitrary constants which are unlikely to be correct for any particular situation and for which the tuning seems to be a black art. 5. In an N node cluster, only 1/N of the dropped locked will actually contribute to solving the problem on average. So all in all we are better off without it. This also makes merging the lock_dlm module into GFS2 a bit easier. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [GFS2] Fix ordering bug in lock_dlmSteven Whitehouse2008-06-27
| | | | | | | | | | | | | | | | | This looks like a lot of change, but in fact its not. Mostly its things moving from one file to another. The change is just that instead of queuing lock completions and callbacks from the DLM we now pass them directly to GFS2. This gives us a net loss of two list heads per glock (a fair saving in memory) plus a reduction in the latency of delivering the messages to GFS2, plus we now have one thread fewer as well. There was a bug where callbacks and completions could be delivered in the wrong order due to this unnecessary queuing which is fixed by this patch.

* [GFS2] Clean up the glock coreSteven Whitehouse2008-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a number of cleanups to the core of the GFS2 glock code. As a result a lot of code is removed. It looks like a really big change, but actually a large part of this patch is either removing or moving existing code. There are some new bits too though, such as the new run_queue() function which is considerably streamlined. Highlights of this patch include: o Fixes a cluster coherency bug during SH -> EX lock conversions o Removes the "glmutex" code in favour of a single bit lock o Removes the ->go_xmote_bh() for inodes since it was duplicating ->go_lock() o We now only use the ->lm_lock() function for both locks and unlocks (i.e. unlock is a lock with target mode LM_ST_UNLOCKED) o The fast path is considerably shortly, giving performance gains especially with lock_nolock o The glock_workqueue is now used for all the callbacks from the DLM which allows us to simplify the lock_dlm module (see following patch) o The way is now open to make further changes such as eliminating the two threads (gfs2_glockd and gfs2_scand) in favour of a more efficient scheme. This patch has undergone extensive testing with various test suites so it should be pretty stable by now. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> Cc: Bob Peterson <rpeterso@redhat.com>

* [GFS2] Invalidate cache at correct pointBenjamin Marzinski2008-03-31
| | | | | | | | | | | | | | | | GFS2 wasn't invalidating its cache before it called into the lock manager with a request that could potentially drop a lock. This was leaving a window where the lock could be actually be held by another node, but the file's page cache would still appear valid, causing coherency problems. This patch moves the cache invalidation to before the lock manager call when dropping a lock. It also adds the option to the lock_dlm lock manager to not use conversion mode deadlock avoidance, which, on a conversion from shared to exclusive, could internally drop the lock, and then reacquire in. GFS2 now asks lock_dlm to not do this. Instead, GFS2 manually drops the lock and reacquires it.

| * [GFS2] Check for installation of mount helpers for DLM mountsFabio Massimo Di Nitto2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch is a fix to abort mount if the mount.gfs* and possible umount.* are missing from /sbin. While we do what we can to guarantee that they are installed properly in userland (CVS HEAD), we want to make sure that mount still aborts properly. The only sign of missing helpers is that lock_dlm will receive no mount options at all. According to David the problem does not exist for lock_nolock as the helpers are not required. The patch has been tested for both gfs and gfs2 and it works as expected. The lack of mount.gfs* will generate an error that is propagated to mount: oot@node1:~# mount -t gfs2 /dev/nbd2 /mnt/ mount: wrong fs type, bad option, bad superblock on /dev/nbd2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so [ 3513.303346] GFS2: fsid=: Trying to join cluster "lock_dlm", "gutsy:gfs2" [ 3513.304546] DLM/GFS2/GFS ERROR: (u)mount helpers are not installed properly!

* | [GFS2] GFS2: chmod hung - fix race in thread creationBob Peterson2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem boiled down to a race between the gdlm_init_threads() function initializing thread1 and its setting of blist = 1. Essentially, "if (current == ls->thread1)" was checked by the thread before the thread creator set ls->thread1. Since thread1 is the only thread who is allowed to work on the blocking queue, and since neither thread thought it was thread1, no one was working on the queue. So everything just sat. This patch reuses the ls->async_lock spin_lock to fix the race, and it fixes the problem. I've done more than 2000 iterations of the loop that was recreating the failure and it seems to work.

* [GFS2] Use void * instead of typedef for locking module interfaceSteven Whitehouse2006-09-08
| | | | | | | | | | | As requested by Jan Engelhardt, this removes the typedefs in the locking module interface and replaces them with void *. Also since we are changing the interface, I've added a few consts as well.
