Hi all, So I have finally finished the v3 of reflink for ocfs2. The biggest change is that we support 64bit cluster offset now(Thank Mark and Joel for it).

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

The patch was created against a 1.4 tree. However, it applies cleanly to mainline too. The patch has been lightly tested. I am running fill_verify_holes on a non sparse volume currently. Please review. Sunil

One line fix from Joel's version. Also, some comments removed. 18:58 <sunil> wc->w_first_new_cpos = 18:58 <sunil> - ocfs2_align_bytes_to_clusters(inode->i_sb, i_size_read(inode)); 18:58 <sunil> + ocfs2_clusters_for_bytes(inode->i_sb, i_size_read(inode));

The new code is dedicated to calculate free inodes number of all inode_allocs, then return the info to userpace in terms of an array. Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent' from userspace, is now going to be involved. setting the flag on means no cluster coherency considered, usually, userspace tools choose none-coherency strategy by

Add online resize in tunefs.ocfs2 so that user can increase the volume when it is mounted.

Two patches follow this message. One fixes the default implementation of SEEK_HOLE/DATA. This patch applies atop Josef's last posted patch. The second patch implements the same on ocfs2. The test tool for the same is available here. http://oss.oracle.com/~smushran/seek_data/seek_test.c It is improved since the last post. It runs cleanly on zfs, ocfs2 and ext3 (default behavior).

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

I am still having this weird problem with nodes hanging while I'm running OCFS. I'm using OCFS 1.0.9-12 and RHAS 2.1 I've been working on tracking it down and here's what I've got so far: 1. I create a file from node 0. This succeeds; I can /bin/cat the file, append, edit, or whatever. 2. From node 1, I do an operation that accesses the DirNode (e.g. /bin/ls) 3. Node 0

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct
