Description
When the available disk space is small (specifically, less than 5GB), the system's automatic disk expansion feature fails to work.
Impact
This prevents the database from automatically acquiring more disk space when needed on systems with limited initial storage, potentially leading to service interruptions or failures if the disk becomes full.
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
The issue names no files, tests, or entry points. Start by reproducing automatic expansion with less than 5GB available, then trace the disk-expansion path and its existing coverage. Done means expansion succeeds on small disks without service interruption, with a regression test covering the threshold.
