All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil

Hello, We just experienced a hang that looks superficially very similar to http://www.mail-archive.com/ocfs2-users at oss.oracle.com/msg02359.html There are 3 nodes in the cluster ocfs2-1.4.1 rhel 5.2. Versions, uname's in the attached text file which also includes fs_locks dumps and various other diagnostics. The lock up happened when we were restarting a java application that was

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

Hello, First of all, i am new at the list and i have several questions about ocfs2 performance. Where i am working i am having huge performance problens with ocfs2. Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI. ( acctualy 3 LUNS, 3 ocfs2 clusters ) I am not the one who configured the envoriment, but it is making the performance of my MAIL

These patches convert the mle list to a hash. The same patches apply on ocfs2 1.4 too. Currently, we use the same number of hash pages for mles and lockres'. This will be addressed in a future patch that will make both of them configurable. Sunil

The changes from the last drop are: 1. Patch 11 removes struct dlm_lock_name. 2. Patch 12 is an unrelated bugfix. Actually is related to a bugfix that we are retracting in mainline currently. The patch may need more testing. While I did hit the condition in my testing, Marcos hasn't. I am sending it because it can be queued for 2.6.30. Give us more time to test. 3. Patch 13 will be useful

Please review the list of patches being applied to the ocfs2 1.4 tree. All patches list the mainline commit hash. Thanks Sunil

Linus, et al, Here are the ocfs2 changes for 2.6.37. There are three major additions. Tao Ma has added readahead to our CoW operations. Sunil Mushran has added a global heartbeat mode, allowing one device heartbeat to support multiple ocfs2 mounts. Finally, Patrick J. LoPresti has done the final work to enable ocfs2 mounts on devices larger than 16TB. The ocfs2 disk format has always

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

The versioning information is confusing for end-users. The numbers are stuck at 1.5.0 when the tools have moved to 1.8.3. I suggest removing the versioning system in the kernel altogether and let the kernel version be the guide to debug issues. However, if you think versioning is still required, please state the reason and modify the version string in the ver.* files to reflect the uptodate

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.

Found 15 patches (out of 162) that appeared relevant to ocfs2 1.4. Please review. Sunil
