This is a major release that includes a number of changes. Many improvements contribute to better support of Gluster with containers and running your storage on the same server as your hypervisors. Additionally, we’ve focused on integrating with other projects in the open source ecosystem. This releases marks the completion of maintenance releases for Gluster 3.6. Moving forward, Gluster versions 3.9, 3.8 and 3.7 are all actively maintained.

Hey folks,

Gluster test infrastructure needs a bit of attention. We have committed a lot of code in the last couple of years, but we have not scaled our infrastructure at the same rate. Lately, the signs have become alarming and it calls for attention.

The agenda of the meet is to educate new Devs about
1. Current Gluster test framework - TAP, prove, include.rc.
2. Challenges
     a. Regression takes a lot of time to run
     b. We have so many non-deterministic tests 
     c. Identifying cause  for test failure takes time
     d. NetBSD debugging knowledge in the community is scarce.
     e. DISTAF: Multinode testing is not integrated with regression yet.
     f. More types of tests to have: upgrade, performance, integration.
     g. unit tests 

Note that agenda is mainly to showcase the current challenges through a medium more informative than email/irc. It is not to discuss possible solutions; that should be done over email on the gluster-devel mailing list.

Hence this hangout is scheduled keeping in view convenience of devs from IST or around. We will have the session recorded for everyone to view at their own convenience. Also we could do the same session for different time zones.
This Hangout On Air is hosted by Raghavendra Talur. The live video broadcast will begin soon.

Introducing the Tiering feature.
Simulating Race Conditions · Tiering feature is introduced in Gluster 3.7 release. Geo-replication may not perform well with Tiering feature yet. Races can happen since Rebalance moves files from one brick to another brick(hot to cold and cold to hot), but the Changelog/Journal remails in old ...

anyone using glusterfs as cinder/nova image block storage?
we are running with this configuration and saw some severe limitations;
Would be great to hear feedback from industry peers using this configuration;
Major problem with this approach:
1. for the vm image(say 100gb), it is stored as a single file  in a single brick(say 1TB), the brick); With thin provision,  the vm image file maybe 10g in the first week ,  and cinder may put 20 vm images on this brick(still 10gb*30=300gb size); With vm growing after a while, each vm is at 33gb and it is supposed to be able to grow th 100gb; But we run out of disk space on this brick; -----so we have to rebalance; with rebalance, we found some IO heavy VM got read-only while we do rebalance; 

2. Say we have 3 node glsuterfs cluster, with 1TB storage each(one brick of 1 TB filesystem, each with 600gb storage used); with one node down for 10 min, and the files are consistently modified by VM(as vm always running), when the node goes back online, all the vm images are different from other 2 copy vm files; so we have to re-sync the full 600gbfiles from other 2 nodes?  what is the exact logic behind it does the re-sync?

Hi, I use gluster for cinder/nova instances.

For 1/. have you tried using striped volumes to shard 'large' files throughout the cluster?

Judging by the release notes, it appears that 2/. is a known problem. Have you tried using the 3.6.x series[1]? I haven't seen it packaged for any of the distros that I use, so you may have to be creative and do a lot of preflight testing before you push it into production. Features that might be helpful for this use case is the addition of Erasure Coding (disperse translator) and AFRv2 (has some consequences for the self heal daemon).

About this community

GlusterFS is a clustered file-system capable of scaling to several brontobytes. It aggregates various storage bricks over TCP/IP or Infiniband RDMA into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 server with SATA drives and Infiniband or GigE interconnect.

This has nothing to do with GlusterFS other than some fuse mounts later in the video that are not discussed in the video..

My report on Gluster @ FOSDEM'16
My first FOSDEM, and it was awesome. I got to meet a lot of GlusterFS users and understood a lot about how they use GlusterFS. And I also got to meet and hear Gophers at the Go Devroom. Thank you...
