...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 in case inode ste...

Hello list: Is there any way to implement a GPO for linux clients with samba4? Best regards

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.

...h 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

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

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 :) Changes from la...
