Disk Space Crisis
MediumRHCSA Prep20-30 minThe brief
An alert says the root filesystem is nearly full. Two large junk files are the culprits: a rotated legacy log at /var/log/legacy/app.log.1 and a leftover core dump at /var/crash/core.12345. Find the large files and remove the junk — but do NOT touch the application database at /var/lib/appdb/data.db (it's large but live).
What you'll do
- Locate files over 100MB (df / du / find -size)
- Remove the stale rotated log
- Remove the leftover core dump
- Leave the live database intact
