similar to: [GIT PULL] ocfs2 changes for 2.6.37

Linus et al, Here is the second batch of ocfs2 changes for 2.6.36. We've ironed out all of the ordering with the extN/jbd2 folks, and they have stewed for a little as well. There's nothing large in here. ocfs2 has long supported devices larger than 2^32 sectors in the code; we now toggle that capability on. Tao has added readahead to our CoW operations. We also have one more ECC fix

Linus et al, Here are the ocfs2 updates for 2.6.35. There are two major changes. Mark added allocation reservations to our node-local allocators. This gets us much more contiguousness when many processes are growing files in parallel. On the other end of contiguousness, ocfs2 has had a major limitation since the beginning. When ocfs2 needs new inodes, it has always grown its metadata

Linus, et al, Here are the major ocfs2 fixes for 2.6.35-rc5. A few more fixes have trickled in, but as these major fixes have been tested, I didn't want to delay them any longer. The first major fix you know about: the tail zeroing fix when extending files. It's been run under heavy testing for a week now, and we're quite happy. We should also no longer be touching any pages past

These patches comprise the bulk of our outstanding changes for Ocfs2 and Configfs. Configfs gets some lockdep updates, and we remove it's EXPERIMENTAL tag as things have been quite stable for some time now. Ocfs2 gets fixes that made it in too late for 2.6.24, and several new features. The most interesting are listed below: We've been on the path to removing the "vote"

Linus et al, Here are the last ocfs2 and configfs fixes for 2.6.39-rc. These include a configfs crash and a compatibility regression in the ocfs2 internal DLM. Please pull.

All, We are pleased to announce the release of OCFS2 1.4.10-1 and OCFS2 tools 1.6.3-2 for Oracle Linux 5 Update 7 and higher and Redhat Enterprise Linux 5 Update 7 and higher. Oracle's Unbreakable Linux Network users who are subscribing to the "OCFS2 1.4 packages for Enterprise Linux 5" channel can upgrade to this release by running up2date. Red Hat's Enterprise Linux 5

In reflink we update the id info in the disk but forget to update the corresponding information in the VFS inode. So update them accordingly in case we want to preserve the attributes.

Hello, I have an active, balanced webcluster with 2 SLES10SP2 nodes, both running ocfs2 with an iscsi target. The ocfs2 volume is mounted on both nodes. Everything works fine, except sometime the load on both systems go as high as 200, then both systems freeze, only reboot helps to regain control. I noticed that this behaviour does not occur when the cluster is NOT balanced. When the load on both

As we test the ocfs2 cluster, the cluster is sometime hangs up. I got some information about the dead lock, which cause the cluster hangs up, the sys dir / lock is held and the node did not release it which cause the cluster hangs up. root at cvknode-21:~# ps -e -o pid,stat,comm,wchan=WIDE-WCHAN-COLUMN | grep D PID STAT COMMAND WIDE-WCHAN-COLUMN 7489 D jbd2/sdh-621

Currently the process of dlm join contains 2 steps: query join and assert join. After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount

As part of adding support for OCFS2 to mount huge volumes, we need to check that the sector_t and page cache of the system are capable of addressing the entire volume. An identical check already appears in ext3 and ext4. This patch moves the addressability check into its own function in fs/libfs.c and modifies ext3 and ext4 to invoke it.

After some parallel mount/umount test on ocfs2, we got this: slab error in kmem_cache_destroy(): cache `o2dlm_mle': Can't free all objects. Then we found a memleak situation in dlm_add_migration_mle(). When a mle found, it will be removed from dlm->hlist. If there is no pointer to it at that moment, the mle will become an ?orphan mle? that no process can find and release.
