VDO
by Miroslav Suchý 04 Jul '26

04 Jul '26

After I seen the talk about VDO: https://www.youtube.com/watch?v=7CGr5LEAfRY I went ahead and tried it. I tried it on small (12GB) sample of Copr data and I saved 20-30% data. I then deployed it on production server retrace.fedoraproject.org and saved there 15% out of 2TB. Several notes: The RPM packages are only available for RHEL. Recently the public github has been updated with version of VDO, which should work on Fedora. No RPM available for Fedora yet though. Here are my notes: # vdo create --name=vdo1 --device=/dev/vdb --vdoLogicalSize=1T # mkfs.ext4 /dev/mapper/vdo1 Some slides suggest to use -E discard. This is not needed for new volumes. See vdo-devel mailing list for reasoning. # mount -o discard /dev/mapper/vdo1 /mnt/a Probably best scenario is to create vdo on whole disk and then make PV from whole VDO disk and put LVM on top of that. When you already have data, you cannot convert your disk to VDO. You need create new VDO disk, format it, mount it and copy the data. In my case, due limited space for migration I created a small LVM volume "vdosrv": # lvcreate -L 80G -n vdosrv vol0 I converted it to VDO which claims to have 2TB of vitual total size # vdo create --name=srv18 --device=/dev/vol0/vdosrv --vdoLogicalSize=2T # mkfs.ext4 /dev/mapper/srv18 See how many space is *actually* free. # vdostats # mkdir /mnt/srv18 # mount -o discard /dev/mapper/srv18 /mnt/srv18 Now I moved some data from old volume to /mnt/srv18. I shrank the FS of old volume, I shrank the old LV. And then I enlarged the new LV. # lvresize -L +400G /dev/vol0/vdosrv and let know vdo that it can use the new space: # vdo growPhysical -n srv18 I repeated this several times. I have to say that my experience is so far good. I hope that my notes help someone. Miroslav

About JS framework
by Pierre-Yves Chibon 17 Oct '22

17 Oct '22

Good Morning Everyone, Our infrastructure is mostly a python store, meaning almost all our apps are written in python and most using wsgi. However in python we are using a number of framework: * flask for most * pyramid for some of the biggest (bodhi, FAS3) * Django (askbot, Hyperkitty) * TurboGears2 (fedora-packages) * aiohttp (python3, async app: mdapi) While this makes sometime things difficult, these are fairly standard framework and most of our developers are able to help on all. However, as I see us starting to look at JS for some of our apps (fedora-hubs, wartaa...), I wonder if we could start the discussion early about the different framework and eventually see if we can unify around one. This would also allow those of us not familiar with any JS framework to look at the recommended one instead of picking one up semi-randomly. So has anyone experience with one or more JS framework? Do you have one that would you recommend? Why? Thanks for your inputs, Pierre

The packages app has a short runway
by Randy Barlow 24 Apr '20

24 Apr '20

Greetings! The packages app is running on Fedora 30, and its dependencies are not available in Fedora 31+ as I understand it. This means it has about 7 months before we need to do something about it, or shut it off. Do we know if it can run on RHEL 7?

Yes, that is exactly the case. We recently looked at this to see if we could retire the service, but it looks like it's still needed, so we need to figure out how to get cycles to update it. If someone wants to work on this, let us know! kevin

Pagure for EL8 (EPEL8)
by Neal Gompa 26 Mar '20

26 Mar '20

Hey all, In the interest of helping to modernize the infrastructure Fedora runs on, I'm working on introducing Pagure into EPEL8. This will hopefully allow us to upgrade our Pagure instances to use RHEL 8 instead of RHEL 7, and notably, make the transition (mostly) complete for moving all Python software Fedora runs to Python 3. I've done an early build locally to determine what's needed to make this possible. The following report from DNF indicates the missing packages that need to be added to EPEL 8 before I can introduce Pagure into EPEL8: Problem 1: conflicting requests - nothing provides python3-jenkins needed by pagure-ci-5.8-1.el8.noarch Problem 2: conflicting requests - nothing provides gitolite3 needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(binaryornot) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(celery) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(flask-wtf) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(redis) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(straight.plugin) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(wtforms) needed by pagure-5.8-1.el8.noarch - nothing provides python3.6dist(pygit2) >= 0.26.0 needed by pagure-5.8-1.el8.noarch Problem 3: conflicting requests - nothing provides python3-trololio needed by pagure-ev-5.8-1.el8.noarch One of the reasons I'd like to have this done sooner rather than later is so that we can drop Python 2 support from Pagure with version 6.0. I think it's quite reasonable to say that version 6.0 isn't going to happen until we can get our Pagure servers running on EL8 using Python 3. So now, I need some help making this happen. I already own trololio, and I'm going to make that available in EPEL 8 ASAP. Can anyone help with some of the other dependencies here? Thanks in advance, Neal -- 真実はいつも一つ！/ Always, there's only one truth!

Fedora 32 Beta Freeze now in effect
by Kevin Fenzi 18 Mar '20

18 Mar '20

Greetings. We are now in the infrastructure freeze leading up to the Fedora 32 Beta release. This is a pre release freeze. We do this to ensure that our infrastructure is stable and ready to release the Fedora 32 Beta when it's available. You can see a list of hosts that do not freeze by checking out the ansible repo and running the freezelist script: git clone https://infrastructure.fedoraproject.org/infra/ansible.git ansible/scripts/freezelist -i inventory Any hosts listed as freezes is frozen until 2020-03-17 (or later if release slips). Frozen hosts should have no changes made to them without a sign-off on the change from at least 2 sysadmin-main or rel-eng members, along with (in most cases) a patch of the exact change to be made to this list. Thanks, kevin

Revamping the Release Readiness meeting
by Ben Cotton 05 Mar '20

05 Mar '20

(Posting to many mailing lists for visibility. I apologize if you see this more times than you'd like.) You may have already seen my Community Blog post[1] about changing the Release Readiness meeting process. The meeting has questionable value in the current state, so I want to make it more useful. We'll do this by having teams self-report readiness issues on a dedicated wiki page[2] beginning now. This gives the community time to chip in and help with areas that need help without waiting until days before the release. I invite teams to identify a representative to keep the wiki page up to date. Update it as your status changes and I'll post help requests in my weekly CommBlog posts[3] and the FPgM office hours[4] IRC meeting. The Release Readiness meeting will be shortened to one hour and will review open concerns instead of polling for teams that may or may not be there. We will use the logistics mailing list[5] to discuss issues and make announcements, so I encourage representatives to join this list.

28 Feb '20

--- title: CPE Weekly status email tags: CPE Weekly, email --- # CPE Weekly: 2020-02-28 Background: The Community Platform Engineering group is the Red Hat team combining IT and release engineering from Fedora and CentOS. Our goal is to keep core servers and services running and maintained, build releases, and other strategic tasks that need more dedicated time than volunteers can give. For better communication, we will be giving weekly reports to the CentOS and Fedora communities about the general tasks and work being done. Also for better communication between our groups we have created #redhat-cpe on Freenode IRC! Please feel free to catch us there, a mail has landed on both the CentOS and Fedora devel lists with context here. ## Fedora Updates * F32 Beta Freeze now on ### Data Centre Move * Old OpenStack instance has now been switched off. * The team are planning the shipping logistics of the equipment across country with Red Hat - measurements, weights, insurance amounts - fun stuff! :) * No changes to our expected dates as per our last posting, but if there are we will make sure to let you know asap. ### AAA Replacement Current functionalities developed to date: * User functionality to join groups * Uhange email address and password * Disable account function * Database access function * We are also currently mapping solution on how best to have users move from the current FAS to the new FAS (potential name incoming!). * The team also came to the end of developing our wireframes and mapping our user experience flow. * Unit tests were carried out regarding password controller and the current codebase. Patrick Uiterijk and Christian Heimes still continue to be a huge help to the team in this project so thank you both sincerely! For our full blog post, check out Ben Cottons weekly For more information regarding outstanding issues, please see here. To view our current scrum board, please see here. ### CI/CD * The team have made good progress on getting monitor-gating to run in staging * This is running completely now and while it fails in some steps but not because of itself, means it is already providing us valuable information :) * The team have sent an email to the devel list presenting our ideas and potential proposal for the changelog and release fields proof of concept - check it out here: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org… ### Sustaining Team * Releng and Infra Freeze for Fedora 32 Beta is now, so if you need changes have them reviewed. * FMN is the main blocking point for the retirement of fedmsg, it is also running on an eol Fedora (28) and the team are working on replacing it. Check out their public thread here: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org… ## Docs ### Misc Updates * Some packaging work to get pagure's dependencies added and built in EPEL8 (remaining: pygit2 and celery) were done this week * boot.fedoraproject.org and keys.fpo to wiki page has been retired * koji is being set up to have rhscl and rhdevtools for EPEL-7 * infra 8664 - newer kernel on aarch64-test machines. * infra 8369 - people css and html broken so a patch has been applied from new contributor and pushed out * Investigations into why fedora 32 branched compose was stuck & it was ostree signing. https://pagure.io/robosignatory/issue/44 https://pagure.io/pungi/issue/1350 * Broken epel8-testing update push was fixed and is now resumed * Rawhide compose failure was investigated https://pagure.io/releng/failed-composes/issue/1023 Was ceph. Filed https://bugzilla.redhat.com/show_bug.cgi?id=1805422 untagged it and refired compose. * Vagrant environment for mbbox was worked on https://github.com/fedora-infra/mbbox/pull/1 * Mbbox was moved to fedora-infra https://github.com/fedora-infra/mbbox * Jms-messaging-plugin PRs merged https://github.com/jenkinsci/jms-messaging-plugin/pull/169 https://github.com/jenkinsci/jms-messaging-plugin/pull/168 * Alternative “holistic heuristic” algorithm for computing releases was implemented https://pagure.io/Fedora-Infra/generate_changelog/pull-request/3 Common Python package, modules and misc cleanup https://pagure.io/Fedora-Infra/generate_changelog/pull-request/4 * Update and complete README was worked on https://pagure.io/Fedora-Infra/generate_changelog/pull-request/5 ## CentOS Updates ### CentOS * 5 updates for el8 * 3 updates for el7 * EPEL7 container image on quay.io for python-tox * Exploring fedora-infra jobs that can be containerized ### CentOS Stream * Composes are now automated * CentOS QA are now consuming compose in the test suite and running against CentOS Linux and Stream! * Building the contributor workflow is still ongoing and we will keep you updated when we make some progress on this As always, feedback is welcome, and we will continue to look at ways to improve the delivery and readability of this weekly report.
