similar to: [git patches] Ocfs2 and Configfs fixes

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"

The only non-fix here is Joel's new configfs convenience macros, but nobody is using them yet, so I think the patch is safe. By the way, these patches (as usual) are all rebased on top of your latest tree. I think that since the vast majority of ocfs2 and configfs patches are self-contained and within a small area of the kernel that this should probably be fine. If you feel otherwise however,

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

I've seen others with a similar problem, but have yet to find a solution. I'm using CentOS 4.4, installed the ocfs2 package to match my kernel. Installed ocfs2tools. I can open the ocfs2console just fine, but when trying to add a node, it tells me the cluster stack could not be loaded. When I do /etc/init.d/o2cb configure, I get: Cluster to start on boot (Enter "none" to clear)

Hi, The following patches fix few bugs/APIs in configfs. The third one depends on the patch introducing configfs_dirent_lock previously submitted in http://lkml.org/lkml/2008/6/12/232 Louis -- Dr Louis Rilling Kerlabs Skype: louis.rilling Batiment Germanium Phone: (+33|0) 6 80 89 08 23 80 avenue des Buttes de Coesmes http://www.kerlabs.com/ 35700 Rennes

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

I was able to get the source code for ocfs2 and compile it. This worked and created the necessary .ko files Now I have to figure out why gnu parted 1.6.15 has bugs. when I try a partprobe on a partitioned firewire maxtor drive mount -t ocfs2 /dev/sdb1 /u01/oradata/orcl It says no such device.... Any ideas anyone?... Regards, Mandar Vengurlekar ----- Original Message ----- From: Mandar P

In ocfs2_remove_btree_range, when calling ocfs2_lock_refcount_tree and ocfs2_prepare_refcount_change_for_del failed, it goes to out and then tries to call mutex_unlock without mutex_lock before. And when calling ocfs2_reserve_blocks_for_rec_trunc failed, it should free ref_tree before return. Signed-off-by: Joseph Qi <joseph.qi at huawei.com> --- fs/ocfs2/alloc.c | 8 ++++---- 1 file

This patch plugs a race between the downconvert thread and an unlock ast message. Specifically, after the downconvert worker has done its task, the dc thread needs to check whether an unlock ast made the downconvert moot.

ocfs2_quota_write needs to release the lock if it fails to read quota block. So use "goto out" instead of "return err".

Hello. I plan to use OCFS2 + DRBD for email server. Problem: I use "seeker" for testing http://www.linuxinsight.com/how_fast_is_your_disk.html And get this: Results: 65 seeks/second, 15.23 ms random access time Then I do rm of many files - it fals to 10 seeks/second and performance is terrible. What can I do to increase it? What`s wrong? Below is many info. What we have: Debian

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call

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.

ocfs2_read_virt_blocks() does BUG when we try to read a block from a file beyond its end. Since this can happen due to filesystem corruption, it is not really an appropriate answer. Make ocfs2_read_quota_block() check the condition and handle it by calling ocfs2_error() and returning EIO.
