Hi all, This patch set adds batched discard support to ocfs2. Please check. Thanks. Regards, Tao

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

Another simple question. How do I calculate the size of the volume from the superblock? Do I just use the two fields: u_int32_t s_blocksize_bits; /* Blocksize for this fs */ u_int32_t s_clustersize_bits; /* Clustersize for this fs */ What is the formula to use? Thanks, John

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));

Hi, We are trying to use OCFS2 as VM storage. After running into problems with qemu's disk_mirror feature we now think there could be a problem with the FIEMAP ioctl in OCFS2. As far as I understand the situation looks like this: Qemu inquiries the FS if the given section of the image is already allocated via the FIEMAP ioctl [1] It especially checks if fm_mapped_extents is greater 0.

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).

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

Hi, These three patches fix the problems in the version two. And them base on the Tao's patches: ocfs2/xattr: xattr improvement The first patch fix some problem in xattr code. The second patch add security EA support. The third patch add ACL support. Best regards, tiger

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

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. For the design doc, please

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 v3 of reflink for ocfs2. The biggest change is that we support 64bit cluster offset now(Thank Mark and Joel for it).

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
