...us allocated with unwritten and then divide it by write to the 256 with 1 cluster. Now if we try to write 40960 bytes at offset 256. We will panic. Why? The reason is that: 1. with ppc box, we have page_size=64K. So in one ocfs2_write_begin_no_lock we will try to handle 40960 bytes together. 2. in ocfs2_lock_allocators we will get that no metadata is need since the 2nd extent block has so many empty extent recs. 3. then write begin one cluster by one in ocfs2_write_cluster. 1) The 1st cluster(256) nothing special. 2) the 2nd (257), it will be merged with 256. 3) the 3rd (258), be merged with 256....

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

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. For the design doc, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/RefcountTrees http://oss.oracle.com/osswiki/OCFS2/DesignDocs/ReflinkOperation

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, 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

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
