This blog runs anonymously — what matters here are the fixes, not the names. Here’s who’s behind it. I’m the person people call not to “build us a website,” but when “everything’s down, figure it out.” I taught myself to code long before my first job in IT. Nobody wanted to hire a self-taught developer without experience, so I got in through QA: two years hunting other people’s bugs before I wrote a line of production code myself.https://bitpage.me/infra/migrate-docker-app-dying-disk/Fri, 24 Jul 2026 11:35:00 +0000https://bitpage.me/infra/migrate-docker-app-dying-disk/Short answer: When the source server’s disk fails on writes but still reads fine, treat it as read-only hardware. Stream pg_dump -Fc over SSH straight to the target machine, pull Docker images from your registry instead of rebuilding end-of-life Dockerfiles, and anchor every rsync exclude with a leading slash. That moved a 14-service app with a 12 GB PostgreSQL database onto a new node without a single write to the failing disk.
