WenyXu opened a new issue, #3052:
URL: https://github.com/apache/incubator-opendal/issues/3052
We designed some chaos tests, which simulate what problems will occur when
the disk is full.
**Prepares**
```
fallocate -l 512K disk.img
mkfs disk.img
mkdir ./td
sudo mount -o loop td.img ./td
chmod a+wr ./td
```
**Codes**
```rust
#[tokio::test(flavor = "multi_thread")]
async fn object_store_write() {
let mut builder = object_store::services::Fs::default();
let root_dir = "/tmp/chaos/td/";
let _ = builder.root(root_dir);
let store = ObjectStore::new(builder).unwrap().finish();
// XKB
let data = [96u8; 1024 * 512]; // The writable was smaller than 512KB
store.write("/test", data.to_vec()).await.unwrap();
}
```
The test was expected to raise `no space` errors, but it didn't.
```
test tests::standalone_read_write::object_store_write ... ok
```
However, if we check the written file, it only contains partial bytes.
```bash
➜ td ls -lh
total 448K
drwx------ 2 root root 16K Sep 13 08:28 lost+found
-rw-rw-r-- 1 weny weny 428K Sep 13 09:10 test
```
