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

From: Xue jiufei <xuejiufei at huawei.com> Subject: ocfs2: dlm_request_all_locks() should deal with the status sent from target node dlm_request_all_locks() should deal with the status sent from target node if DLM_LOCK_REQUEST_MSG is sent successfully, or recovery master will fall into endless loop, waiting for other nodes to send locks and DLM_RECO_DATA_DONE_MSG to me. NodeA

dlm_request_all_locks() should deal with the status sent from target node if DLM_LOCK_REQUEST_MSG is sent successfully, or recovery master will fall into endless loop, waiting for other nodes to send locks and DLM_RECO_DATA_DONE_MSG to me. NodeA NodeB selected as recovery master

Wether the dlm_lock needs to access lvb or not depends on dlm_lock_resource it belongs to. So a new parameter "struct dlm_lock_resource *res" is added to dlm_new_lock() so that we can know if we need to allocate lvb for the dlm_lock. And we have to make the lockres availale for calling dlm_new_lock(). Signed-off-by: Wengang Wang <wen.gang.wang at oracle.com> ---

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

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 all the outstanding ocfs2 fixes for 2.6.31. The major fixes are for aio write and for non-sparse file extending. There are also a couple of b-tree fixes as well as some for quotas. Please pull.

In the current recovery procedure, recovering node recovers orphans from the slot it is holding and the slots that dead nodes were holding. Other online nodes recover orphans from their slots. But orphans in offline slots are left un-recovered. This patch queues recovery_completion for offline slots. Signed-off-by: Srinivas Eeda <srinivas.eeda at oracle.com> --- fs/ocfs2/journal.c | 21

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"

During recovery, a node recovers orphans in it's slot and the dead node(s). But if the dead nodes were holding orphans in offline slots, they will be left unrecovered. If the dead node is the last one to die and is holding orphans in other slots and is the first one to mount, then it only recovers it's own slot, which leaves orphans in offline slots. This patch queues complete_recovery

This is Hide. This is the first contribution. I'd like to configure cluster file system by OCFS2. The number of nodes are two. CompactFlash card(CF) is used as shared DISK. Guarantees of the writing frequency to CF are up to 100,000 times. However, it exceed in two day, due to the disk_heart_beat executed every two seconds. I tried following procedures to solve that. It seems solved. 1.

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging
