How can we reproduce the bug?

1. Creates small file (~2M)

fallocate -l 512K disk.img 
mkfs disk.img 
mkdir ./td
sudo mount -o loop td.img ./td
chmod a+wr ./td

2. Uses above directory as data_home
3. Starts a standalone instance and inserts data until standalone raises a no space error from the wal.
4. Clean up the data_home, and starts a standalone instance, and inserts data before it raises a no space error from wal, flushes the target table, the instance will panic.
5. Copy the above data to a no-space-limited directory
6. Reboot the standalone, you will find the target table is missing.
