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

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

Hello list, I have a ~10TB ocfs2 filesystem in a 8-node cluster. This sits on a logical volume (I know lv is not cluster aware, but I make sure no one touches the lv, while the cluster is running). The LV consists of 5x2TB multipath devices. I recently had errors like this on some nodes: OCFS2: ERROR (device dm-7): ocfs2_check_group_descriptor: Group Descriptor # 0 has bad signature File

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). [View] http://oss.oracle.com/git/?p=tma/linux-2.6.git;a=shortlog;h=refcount [Pull] git://oss.oracle.com/git/tma/linux-2.6.git refcount The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

Before we start accessing a huge (> 16 TiB) OCFS2 volume, we need to confirm that its journal supports 64-bit offsets. So we need to check the journal's feature bits before recovering the journal. This is not possible with JBD2 at present, because the journal superblock (where the feature bits reside) is not loaded from disk until the journal is recovered. This patch loads the journal

As part of adding support for OCFS2 to mount huge volumes, we need to check that the sector_t and page cache of the system are capable of addressing the entire volume. An identical check already appears in ext3 and ext4. This patch moves the addressability check into its own function in fs/libfs.c and modifies ext3 and ext4 to invoke it.

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

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

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

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

Hi, this is the next version of quota support for quota tools. I've addressed all the comments of Tao, Joel and others. Sparse feature disabling also correctly updates quota information now and the patch is merged into the tunefs support patch. Honza

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, below comes a new version of the series of patches implementing quota support for ocfs2-tools. I've fixed the calls of ocfs2_malloc_blocks() which were given number of bytes instead of number of blocks. Besides that the series should be the same. Honza

Hi, I'm sending a series of patches implementing quota support into ocfs2-tools. It's the same as the original huge patch I've sent but now it's split as Joel asked. I've also realized that when disabling SPARSE feature, we should update quota information. That piece of code is missing, I'll implement it soon. Comments welcome. Honza
