We have an application that has many processing threads writing more than a billion files ranging from 2KB ? 50KB, with 50% under 8KB (currently there are 700 million files). The files are never deleted or modified ? they are written once, and read infrequently. The files are hashed so that they are evenly distributed across ~1,000,000 subdirectories up to 3 levels deep, with up to 1000 files

One of ocfs2 filesystem has some errors. 1. fsck.ocfs2 informs me that : "I/O error on channel while reading .. " It was NOT TRUE - I was able to read and write entire storage over the network multiple times. 2. becouse of CRC errors and suggestion to disable metaecc I run tunefs.ocfs2 --fs-features=nometaecc /dev/xxx funefs allocate 9,89 GB of virtual memory and 95% of phisical memory (4GB). After 4 hours process has been killed - because of out of memory. I have to recreate new filesystem and restore data from backup. I try to use tools in version 1.4 a...

Hey everyone, We're coming up on the next merge window, and I only have a couple tiny fixes for ocfs2. I thought I'd list up what I know is outstanding, and I was hoping to find out if I was missing anything. If I am, I need to get it in linux-next and set for the merge window ASAP. - metaecc-stats This is a trivial patch I put together to track errors seen by the blockcheck code. No one has reviewed it. Not a high priority, but I suspect that if it looks good to a reviewer, we can push it whenever we want. - cacheme These are the changes that separate out the metadata cache fr...

Hi List, i'd like to share with you what happened yesterday. Kernel 2.6.36.1 ocfs2-tools 1.6.3 (latest). I had an old OCFS2 partition created with a 2.6.32 kernel and ocfs2 tools 1.4.5. I unmounted all partitions on all nodes in order to enable discontig-bg. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck

Hello. I am experimenting with OCFS2 on Suse Linux Enterprise Server 11 Service Pack 1. I am performing various stress tests. My current exercise involves writing to files using a shared-writable mmap() from two nodes. (Each node mmaps and writes to different files; I am not trying to access the same file from multiple nodes.) Both nodes are logging messages like these: [94355.116255]

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).

...w. I'd like to get these into the merge_window branch sooner rather than later, so any reviews are appreciated :) Changes from last time: - Added inline indexing support. This turned out to be a good idea - many directories just keep their index inlined. - Rebased so it fully complies with metaecc and quota requirements. - Lots of bugs fixed. There's a 'dx_dirs' branch in ocfs2.git: git pull git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git dx_dirs I've tested this batch of patches with kernel builds, and various bash loops to create large numbers of files...

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
