Hi, According to this site, http://oss.oracle.com/osswiki/OCFS2/Roadmap cluster ware flock feature is available in (2.6.25) for Red hat 5.2 U2. But on download page of OCFS2 website I didn't find 2.6.25 version for 64 bit Red Hat Linux 5.2. Current download are only for Red Hat (kernel 2.6.18 ), from where I can download 2.6.25? Thanks Rahee...

...equally) empty groups, new inodes will tend to get spread out amongst them, which in turn can put them all over the disk. This is undesirable because directory operations on conceptually "nearby" inodes force a large number of seeks. For more details, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/InodeAllocationStrategy. So this patch set try to fix this problem. patch 1: Optimize inode allocation by remembering last group. We add ip_last_used_group in core directory inodes which records the last used allocation group. Another field named ip_last_used_slot is also added i...

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

Hi all, this patch set are the backport of inode alloc improvement from mainline to ocfs2-1.4. the patches are almost the same excpet one thing: Joel has added JBD2 support to ocfs2, so he has added "max_blocks" to alloc_context and add a new function "ocfs2_reserve_clusters_with_limit". We don't have that in ocfs2-1.4. So there are some great difference in patch 2.

...ry inodes which records the last used allocation group. Another field named ip_last_used_slot is also added in case inode stealing happens. When claiming new inode, we passed in directory's inode so that the allocation can use this information.

Hi everyone. Does anyone know why the user-space heartbeat (linux-ha) patches from SuSE / Novell are not commited to the mainline ocfs2 source tree? Or are they? Is there an easy way (which does not break the distros package management) to apply these? Thanks, Christian

Currently f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (at least it should be filled with 0). Since in some conditions, f_fsid value might be used as (f_fsid, ino) pare to uniquely identify a file, ocfs2 should return a defined unique f_fsid value from ocfs2_statfs(). This patch uses uuid_hash as a unique ID to initiate f_fsid value, the 32bits width is enough for ocfs2

Tristan, could you please run your xattr test against it? xs->base used to be allocated a 4K size and all the contents in the bucket are copied to the it. So in ocfs2_xattr_bucket_set_value_outside, we are safe to use xs->base + offset. Now we use ocfs2_xattr_bucket to abstract xattr bucket and xs->base is initialized to the start of the bu_bhs[0]. So xs->base + offset will overflow

Hi everyone Firstly, apologies for the cross post, I am not sure which list is most appropriate for this question. I should also point out, that I did not install OCFS2 and I am not the person that normally looks after these kind of things, so please can you bear that in mind when you make any suggestions (I will need a lot of detail!) The problem: accessing certain directories within the

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

Hi everyone, I described the reflink operation at the Linux Storage & Filesystems Workshop last month. Originally implemented as an ocfs2-specific ioctl, the consensus was that it should be a syscall from the get-go. Here's some first-cut patches. For people who have not seen reflink, either at LSF or on the ocfs2 wiki, the first patch contains Documentation/filesystems/reflink.txt to

The following patches implement indexed directory support in Ocfs2, mostly according to the design doc I wrote up a while ago: http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedDirectories The patches have been rebased on top of 2.6.29-rc2. It should be trivial to put them into merge_window. Things are what I'd call complete now. I'd like to get these into the merge_window branch sooner rather than later, so any reviews are appreciated :)...
