[lustre-discuss] File level erasure coding status

[Patrick Farrell]

Hi Stepan!

Erasure coding is very much an in-development feature.  There's some investigatory work going on by James Simmons at ORNL, and the main development effort is tracked here in JIRA:

https://jira.whamcloud.com/browse/LU-10911

The currently in-development code is here - this is the tip of a fairly long branch:
https://review.whamcloud.com/c/fs/lustre-release/+/62757

You can look at the tests in that branch for examples, but note the code is very much in active development.  There is a lot of churn and a number of known bugs.

But if you'd like to follow along, that's where the work is being done.  We'd also be happy to have feedback on the API if you're interested in taking a look.  (In the code - the API has changed some from what's documented in JIRA)

Thanks!
Patrick
