Root Cause

The LlamaIndex persistence file 'index_store.json' was partially written due to a crash, concurrent write, or disk full error, resulting in malformed JSON.

generic

中文

LlamaIndex持久化文件'index_store.json'因崩溃、并发写入或磁盘满错误而部分写入，导致JSON格式错误。

Workarounds

95% success Delete the corrupted persistence directory and rebuild the index from scratch: import shutil import os persist_dir = './storage' if os.path.exists(persist_dir): shutil.rmtree(persist_dir) # Then rebuild index index = VectorStoreIndex.from_documents(documents) index.storage_context.persist(persist_dir=persist_dir)
```
Delete the corrupted persistence directory and rebuild the index from scratch:
import shutil
import os

persist_dir = './storage'
if os.path.exists(persist_dir):
    shutil.rmtree(persist_dir)

# Then rebuild index
index = VectorStoreIndex.from_documents(documents)
index.storage_context.persist(persist_dir=persist_dir)
```
85% success If you have a backup, restore the persistence directory from backup: cp -r ./storage_backup ./storage # Then validate from llama_index.core import StorageContext storage_context = StorageContext.from_defaults(persist_dir='./storage') print('Validation passed')
```
If you have a backup, restore the persistence directory from backup:
cp -r ./storage_backup ./storage
# Then validate
from llama_index.core import StorageContext
storage_context = StorageContext.from_defaults(persist_dir='./storage')
print('Validation passed')
```

中文步骤

删除损坏的持久化目录并从零开始重建索引：
import shutil
import os

persist_dir = './storage'
if os.path.exists(persist_dir):
    shutil.rmtree(persist_dir)

# 然后重建索引
index = VectorStoreIndex.from_documents(documents)
index.storage_context.persist(persist_dir=persist_dir)

如果有备份，从备份恢复持久化目录：
cp -r ./storage_backup ./storage
# 然后验证
from llama_index.core import StorageContext
storage_context = StorageContext.from_defaults(persist_dir='./storage')
print('验证通过')

Dead Ends

Common approaches that don't work:

90% fail
The file contains complex internal state; manual edits often break references between nodes and indices.
70% fail
LlamaIndex attempts to load the existing file first, and fails before overwriting.
