Just so I am clear the upgrade process will be as follows: upgrade all clients to 4.0 rolling upgrade all servers to 4.0 (with GD1) kill all GD1 daemons on all servers and run upgrade script (new clients unable to connect at this point) start GD2 ( necessary or does the upgrade script do this?) I assume that once the cluster had been migrated to GD2 the glusterd startup script will be smart enough to start the correct version? -Thanks On 3 November 2017 at 04:06, Kaushal M <kshlmster at gmail.com> wrote: > On Thu, Nov 2, 2...

Hello All, ? Am replicating in R an analysis I did earlier using SAS. See this as a test of whether I'm ready to start using R in my day-to-day work. ? Just finished replicating a Kaplan Meier analysis. Everything seems to work out fine except for one thing. The 95% CI around my estimate for the median is substantially larger in R than in SAS. For example, in SAS I have a median of 3.29 with a

...us client packages (centos in my case) be able to automatically handle the upgrade vs new install decision, or will we be required to do something manually to determine that? It?s a little unclear that things will continue without interruption because of the way you describe the change from GD1 to GD2, since it sounds like it stops GD1. Early days, obviously, but if you could clarify if that?s what we?re used to as a rolling upgrade or how it works, that would be appreciated. Also clarification that we?ll be able to upgrade from 3.x (3.1x?) to 4.0, manually or automatically? > From: Kaushal...

...nd other RPM based distros) which have well split glusterfs packages currently. At this moment, I don't know exactly how much can be handled automatically, but I expect the amount of manual intervention to be minimal. The least minimum amount of manual work needed would be enabling and starting GD2 and starting the migration script. > > It?s a little unclear that things will continue without interruption because > of the way you describe the change from GD1 to GD2, since it sounds like it > stops GD1.

Hello! We're restarting regular GD2 updates. This is the first one, and I expect to send these out every other week. In the last month, we've identified a few core areas that we need to focus on. With solutions in place for these, we believe we're ready to start more deeper integration with glusterfs, that would be requiring...

I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I...

We have a new GD2 release!! This has been a while coming. The last release happened around the time of the Gluster summit, and we have been working hard the last 2 months. There have been a lot of changes, most of them aimed at getting GD2 in shape for release. We also have new commands and CLIs implemented for y...

I need to upgrade gd from 1.8 to 2.x, but can't find any rpm's to do so. If I try to rebuild a .src.rpm, I get into a dependency hell. Does anyone know how I can accomplish this upgrade without getting into a source install? Mike

We?re highlighting some of the announcements, major features and changes here, but our release notes[1] have announcements, expanded major changes and features, and bugs addressed in this release. Major enhancements: - Management GlusterD2 (GD2) is a new management daemon for Gluster-4.0. It is a complete rewrite, with all new internal core frameworks, that make it more scalable, easier to integrate with and has lower maintenance requirements. This replaces GlusterD. A quick start guide [6] is available to get started with GD2. Although...

After nearly 3 months, we have another preview release for GlusterD-2.0. The highlights for this release are, - GD2 now uses an auto scaling etcd cluster, which automatically selects and maintains the required number of etcd servers in the cluster. - Preliminary support for volume expansion has been added. (Note that rebalancing is not available yet) - An end to end functional testing framework is now available...
