If I have an image of a filesystem taken with dd, I can look at it with a hex editor and discover that an ext2/3 superblock is at offset 1024 and I can figure out a lot of info about it. I cannot figure out, however, how the superblock differs from ext2 in ext3. I can't tell them apart... the "magic number" is the same as well as the "revision" field. If I have such an

Now it's a good time to introduce the new tool 'o2info' since kernel part of OCFS2_IOC_INFO ioctl has been pulld upstream by linus. The following 6 patches have already got sunil's SOBs, and now they're trying to attract more reviewers before it goes to central repo with a modification of getting manual pages being introduced.

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

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
