When ZFS flags a pool as DEGRADED, you are looking at a warning, not a catastrophe — yet. Your data is still accessible, but you have lost a layer of redundancy and every minute counts. I have replaced dozens of failed disks across Proxmox, Ubuntu, and TrueNAS servers over the years, and the procedure is … Read more

If you have ever run zpool status after a scrub and seen a non-zero number under the CKSUM column, you already know the mild panic it triggers. ZFS checksum errors after a scrub mean one thing for certain: data on disk and the checksum stored for that data no longer agree. Whether that one error … Read more

Your Home Assistant installation has been running for a few months, and suddenly things feel sluggish. The history page takes forever to load. Your backups are growing larger every week. You check the filesystem and discover that home-assistant_v2.db has ballooned to several gigabytes. Sound familiar? Database bloat is one of the most common performance problems … Read more

If you are reading this, you probably already know the pain. You set up Nextcloud with external SMB storage pointing to your NAS, and everything looked great during testing with a handful of files. Then you loaded your real library and directory listings started taking 8 to 15 seconds. Uploads crawled at half a megabyte … Read more

If you manage a Nextcloud server, you have probably opened the Admin Overview page and seen a yellow or red warning about background jobs not running via cron. It is one of the most common Nextcloud setup warnings, and our team has run into it across bare metal, Docker, and shared hosting deployments. The warning … Read more

If your Nextcloud gallery crawls when you open a folder full of photos, the fix is usually the same: install the Nextcloud Preview Generator app, generate thumbnails ahead of time, and run a cron job (or systemd timer) to keep them fresh. I have been running self-hosted Nextcloud servers since 2018, and the preview generator … Read more

You ran docker-compose pull, restarted your container, and now your Nextcloud instance refuses to load. Instead of your files and calendar, you see a maintenance screen or a cryptic error about unsupported upgrades. If you are staring at the message “Updates between multiple major versions and downgrades are unsupported,” you have landed in one of … Read more

Immich is a self-hosted, open-source photo and video backup platform that gives you a Google Photos-like experience on your own server. It bundles a web server, PostgreSQL database, Redis cache, and a machine learning service into a single Docker Compose stack that you can deploy in minutes. The catch is that nearly every setup failure … Read more

If your Immich machine-learning container keeps restarting in a loop right after you upgraded Immich, the fastest fix is usually to set IMMICH_HOST=0.0.0.0 in your .env file, then run docker compose pull && docker compose down && docker compose up -d from your Immich folder. That single combination resolves the majority of restart-loop reports we … Read more

If you run a self-hosted Immich server and your CPU spikes to 100 percent every time someone uploads a video, you are not alone. Learning how to enable hardware transcoding in Immich with VAAPI and NVENC is the single biggest performance upgrade you can make, and it takes about 15 minutes once you know the … Read more
