Docker Pulls Keep Timing Out? How to Choose, Configure, and Verify Chinese Registry Mirrors

The short answer

When Docker image pulls fail on a mainland China network, the image is not necessarily missing and DNS is not always the culprit. More often, the public registry path is congested, a mirror is temporarily unavailable, or the configuration was edited but Docker was never restarted.

My practical recommendation is simple: open status.anye.xyz first and treat it as a “weather report” for Docker mirrors; select a recently healthy HTTPS endpoint; edit the correct daemon configuration for your operating system; validate the JSON; restart Docker; and finally verify with a real pull of a small image.

RAID Is Not Backup: How to Choose the Right NAS Layout for Synology, fnOS, and Unraid

The short answer

RAID primarily keeps a NAS available when one or more drives fail. Backup restores data after deletion, ransomware, filesystem damage, theft, fire, or a failed NAS. You normally need both.

On Synology, SHR-1 is the practical default for many homes, while larger and more critical arrays deserve SHR-2 consideration. On fnOS, choose the filesystem, storage mode, drive count, and backup destination as one design. On Unraid, understand that the classic Array is not a conventional striped RAID: data disks keep independent filesystems while one or two parity disks provide failure recovery.

A useful starting rule is: mirror two-drive systems; use single-drive redundancy when capacity matters and a separate backup exists; seriously consider dual-drive redundancy as drive count and individual drive capacity grow. Anything irreplaceable still needs an offline or off-site copy.
