Storage

One hundred megabytes in a chunky blue square: finally, enough room for everything.

A field report on diagnosing and repairing a RAID failure that wasn’t a hardware failure at all — and why ‘replace the disk’ would have made it far worse.

A database stuck forever on ‘starting up’ wasn’t broken — it was clawing its way through WAL replay on a dying disk.

A square of beige plastic that held your whole world in 1.44 megabytes and felt like it could hold the universe.
