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

Infrastructure and release engineering Documentation
by Mark O'Brien 09 Nov '21

09 Nov '21

Hi All, As some of you may be aware there has been chatter around having the documentation for infrastructure and release engineering centralised in one place. A possible solution to this is to move all of these under a new section on docs.fedoraproject.org called something like Infrastructure and Release Engineering (very original I know). We could then go about moving docs which are suitable from currrent locations to the new central point. Each doc should be updated before moving and the old document should be updated to only contain a link to the new doc to avoid a case of multiple versions of a doc (https://xkcd.com/927/ ). The following links contain the bulk of the documentation: https://fedora-infra-docs.readthedocs.io/en/latest/ https://docs.pagure.org/releng/ https://fedoraproject.org/wiki/Infrastructure These would be the suggested first steps with other docs to follow if/when these are completed. As I say this is just a possible solution so as always all feedback and suggestions are encouraged and welcomed. Thanks, Mark

RHEL8 for Copr builders
by Miroslav Suchý 29 May '21

29 May '21

With the sunset of CentOS8 we want to allow builds on top real RHEL in Copr. Now that the RH Developer program is known, what are the option? Do we already use it somewhere? Or I will be the first to use it? :) I need it accessible from AWS so the repos we use in Koji are likely out of the question and I need to use real subscription. Miroslav

Meeting Agenda Item: Introduction Your Name Eddie Jennings, Jr.
by Eddie Jennings 27 May '21

27 May '21

Greetings! My name is Eddie Jennings, Jr., and I'm an IT generalist and system administrator who has been working in the Windows administration space for almost 8 years. For the last couple of years, I've been looking for opportunities to move into the Linux adminstration realm. I've been a Fedora user for several years, and I figure contributing to the infrastructure team would be an opportunity to both gain experience as well as give to the community. Here's the information requested from the Getting Started wiki page. IRC handle: eddiejennings Skills I can offer: - basic BASH and strong PowerShell scripting knowledge - network device configuration and troubleshooting (routers / firewalls and switches) - network service configuration and troubleshooting: DNS (BIND and Windows DNS), DHCP (dhcpd and Windows DHCP), load balancing and reverse proxy (Citrix NetScaler), E-mail (Exchange (on-prem hybrid, and online), Cisco IronPort, Postfix (as a relay)), directory services (Active Directory) - management and configuration of KVM, Hyper-V, and ESXi (am the most familiar with Hyper-V) - basic VoIP (deployed and managed FreePBX) - basic storage knowledge: LVM and working with ext4, xfs file systems. From the Windows world SMB shares, DFS, and NTFS file systems - fundamental knowledge of administering Linux system (more much familiar with RHEL than Debian-based systems) - basic Ansible knowledge Certifications - currently pursuing RHCE certification and hope to sit the exam in August - RHCSA v8 (August 2020) - LPI Linux Essentials (August 2019) Skills I want to gain or sharpen (no particular order and not an exhaustive list): - Using Ansible for infrastructure management - Deeper knowledge of using KVM - Deeper networking skills and knowledge of tools (such as becoming familiar with nftables instead of always relying on firewalld, become familiar with WireGuard, leveraging NginX and HAProxy) - Proficiency with git or other source control systems (ties into working Ansible) - Deeper storage knowledge (leveraging snapshot technology of LVM or file systems like BTRFS, understanding of using SANs to provide block storage) - More proficiency with data backup tools and best practices - Basic database configuration and administration Current Issues that pique my interest: There are two EasyFix tickets regarding Ansible, with which I'd like to see if I can help. There is ticket #9852 regarding DNS that is interesting, as well as #9683 about logging into RedHat bugzilla -- seems like an opportunity to become with an authentication system that isn't Active Directory. I hope this introduction was not too long-winded, but I figure the more I list, the easier it will be to see where I might be able to contribute. I'm looking forwarding to meeting and learning from everyone! -------------------------------- Eddie Jennings, Jr. https://www.eddiejennings.net/
