Mirrorsync error too many client records11/20/2022 ![]() ![]() ![]()
Listening on port 873, it’s able to do everything rsync-over-SSH can do, only without encryption overhead or requiring SSH/shell authentication. I thus opted to use the rsync daemon mode. But while most users know rsync for it’s scp-replacement functionality over SSH, I wanted something more robust without the need for handling SSH keys, and able to be extended further in the future, perhaps to untrusted (and untrusting) 3rd-party mirrors. With the VPSes created, I then looked into file synchronization, and there was only one program on my mind: rsync. In future, as Digital Ocean expands, we’d also be able to add other locations as well, for instance Bangalore, India, Africa, and perhaps additional Europe and South America instances. #MIRRORSYNC ERROR TOO MANY CLIENT RECORDS DOWNLOAD#One worry when first setting up these 4 VPSes was that they would not be enough, but so far, through another major release and several minor releases, we’ve had the complaints about download speed completely stop, so they must be working. : Frankfurt, Germany (not France as commonly assumed!) for Europe and Africa.: San Francisco, California, USA for North/South America West.: Toronto, Ontario, Canada for North/South America East.as well as a dedicated CDN for the same region as the origin server, just in case it got overloaded. Since our origin server is in Toronto, I wanted to ensure we had wide geographic coverage. #MIRRORSYNC ERROR TOO MANY CLIENT RECORDS HOW TO#The next step after crafting a usable file layout was to create some additional VPSes and determine how to synchronize the files. In effect, everything is under a /mirror directory, with external symlinks to provide the root links we wanted. The solution I came up with was the following directory structure: /srv/repository We also had a problem of our “archives”, old stable releases that we did not need or want synchronized to all of our mirror servers wasting space. Mirrorbits requires everything to be housed under one directory, and we needed a way to synchronize this whole directory easily. In Jellyfin’s case, our repository is large and sprawling, constituting many different components including the server, clients, plugins, and various secondary files. The first thing to consider is the layout of the files. I hope the following will help avoid this trouble for anyone else. It seemed to fit the bill exactly.īut there was a problem: documentation on how to actually run Mirrorbits was sparse, so it took quite a bit of trial-and-error to determine how to use it. Mirrorbits is a Go program with a single goal: provide a way to distribute requests from a single central repository to multiple geo-diverse repositories, based on the client’s GeoIP information, handling availability and freshness seamlessly. So one of their talented developers created a solution: Mirrorbits. VideoLAN, creators of the fantastic VLC Media Player, had the same issue of distributing files. Many years before, another FLOSS project had encountered the same problem. I wanted something we could control, and I went looking for a solution - how to effectively create a CDN for file downloads. We had to come up with a better solution.Īs a DIYer at heart, and leading a project built by and for DIYers, I wasn’t content to simply throw CloudFlare in front of the repo - my concerns with that provider notwithstanding. The main complaint was abysmally slow download speeds, and occasionally even full-on timeouts. And users, especially users in Europe and Asia, were having trouble downloading our releases. Jellyfin is a global project, and while I’m personally located in Ontario, Canada, the very vast majority of our users are not. This server, located on Digital Ocean in the Toronto zone, housed both the build process as well as our main repository, served directly via NGiNX.īut this release was the first where we noticed a problem. ![]() Prelude - Pre-10.6.0īefore our 10.6.0 release, we had a fairly simple repository setup: everything would build on a VPS, running Debian, called build1, in response to a GitHub web-hook. ![]() And both for those interested, and for those supporting other similar projects, I’d like to share how we do it. But at Jellyfin, we needed something more robust, something able to handle our needs more elegantly than GitHub or a basic web server could. For many projects, distributing binary assets is easy: put the files on GitHub and you’re done. ![]()
