Microconference - File and Storage Systems

The Linux Plumbers 2013 Microconference-File and Storage Systems track focuses on technologies used in file and storage systems, starting with configuration, monitoring and management technologies and sessions on the traditional file and storage stack. The focus is on efforts that span multiple teams and areas of focus.

The structure will be similar to what was followed the previous years where this is not about listening to long presentations, rather framing a discussion with a few slides or just opening comments and then kicking off a broad discussion with participation by the attendees.

Possible Topics

* Support for SSD's as caching devices - device mapper (Alasdair Kergon, Mike Snitzer, Joe Thornber), bcache (Kent Overstreet), fscache (David Howells)

* Reusing storage and file system code across installation, monitoring and running of systems. SSM (Lukas Czerner), libstoragemgt (Hannes Reineke, Tony Aselon), liblvm (same dm crowd), anaconda people (David Lehman, Dave Cantrell), SuSE snapper (not sure which dev here?), grub/boot (Peter Jones)

* Updates on new “persistent” DRAM class parts - what can we do in the kernel and in application space to support these? (Jeff Moyer, Tejun Heo, Ric Wheeler, FusionIO people (Nisha T, Nick Piggin), Intel people (Willy, Andy Rudoff, other vendors in this space)

* Use cases for new storage/file system features: how to use thinly configured storage? upgrade rollback? data scrubbing? Same crowd as the reuse one above

* Scalability challenges - how big should a single file system be? how many files in a file system? how many file systems per host? Per file system - ext4 devs (Ted, Lukas, Andreas), btrfs (Chris Mason, Josef Bacik, Mingming, etc), XFS (Dave Chinner, Christoph, Alex Elder, Ben Myers)

* Device naming - getting storage devices to have consistent names from BIOS/boot level up to user visible names? Lennart, Peter Jones, Matthew Garrett, etc

* eMMC: what features are missing for parity with SATA? FW update: Work in progress. Do we really need to care about the rest? “Sanitize”, “packed commands” (really?!!), Performance vs Power, etc. (Grant Grundler)


The schedule of the 2013 File and Storage System Plumbers Micro Conference is as follows. Note presentation slides can be found on the Plumbers page by following the links to the abstracts:

  • Session 1 - Presenter 1
  • Session 2 - Presenter 2
  • etc…

Discussion notes

This is a good place to record notes from your session. All too often, if notes were not written down, the session might as well not have happened.
