File and Storage Systems

The Linux Plumbers 2014 File and Storage Track will be focused on current challenges in the IO stack and ongoing work. This will be structured like the Linux File, Storage and Memory management event - individual topics will be discussed with an appointed topic lead, but presentations are actively discouraged. A few slides can be used to help frame the discussion.

Areas of interest are:

• Persistent memory technologies - supporting this new class of devices and work to get our IO performance fast and low latency enough for these new parts.
• SMR Drives - work done to support host aware or restricted mode SMR drives.
• New block layer features provided by device mapper (thin provisioning, dm-cache, etc), BCACHE and other mechanisms.
• Support for user space distributed file systems like Ceph or Gluster
• Highlights of challenges in leading file systems like ext4, xfs, btrfs, NFS, etc.
• Support for copy offload.
• Breaking the file system block size limit of a VM page
• Storage management
• Other topics

Call for Proposals

Submission for Microconferences discussion topics and BOFs are now open [1] and as a File and Storage Systems [2] microconference leads we'd like to invite you to submit your proposals.

You can find the instructions on how to propose a discussion topic here:

http://www.linuxplumbersconf.org/2014/how-to-submit-microconference-discussions-topics/

The Linux Plumbers Conference has officially sold out all of the places, so we encourage submissions for our file and storage microconference from people who have already registered. We will work to get exceptionally compelling session leaders registered, but our ability is limited, so please submit your topics early.

Deadline for submissions is Friday, August 30th at midnight and we will announce the topics on Monday, September 1st.

If you have any questions, please let us know.

Schedule

In past years, we have always done a double session (6 hours, with lunch in the middle). We have always easily filled those slots, so please do submit your topics early if you want to lock in a discussion slot.

Slots will be roughly 45 minutes in length with a discussion leader per slot. Slides are discouraged, but can be used to frame a conversation.

Session Leaders

The leaders of each session will be determined by responses to the call for participation.

Proposed session leaders for key sessions include:

Christoph Hellwig and Dave Chinner - progress on how to architect an intelligent interface between the block and file system layers to enable things like smarter allocation on thinly provisioned storage.

Lukas Czerner, Dave Chinner, Ted Tso - tweaking the block allocator and how to evaluate the change. Xfstests as performance regression test suite.

Ted Tso and Jorge Campello - progress on enablement of SMR drives into ext4

Chris Mason and Josef Bacik - btrfs, are we there yet?

Hannes Reinecke, Tony Asleson, Stef Walter, Tomas Smetana, Lukas Czerner, David Lehman - Storage system management

Jeff Moyer, Christoph Hellwig, James Bottomley - Support for new storage classes (Persistent memory)

Peter Anvin - Erasure encoding and RAID optimization
