How to Diagnose a Website That Fails After a Server Disk Reaches Capacity

When a server filesystem fills, applications may fail to write sessions, caches, uploads, or temporary files.

Checks to make

Check disk and inode usage, identify the full mount and largest growth paths, and correlate with application errors. Preserve logs and customer data; remove only confirmed safe temporary files, then fix retention, monitoring, or capacity before traffic returns to normal.
