Description

__Steps to reproduce:__

1. 3 days ago,the disk is out of space
2. Clean up the disk and free up space
3. And I found Influxdb Can't write new data ,since 3 days ago

__Expected behavior:__
After clean up the disk,InfluxDB can write new data

__Actual behavior:__
I get an error: There is not enough space on the disk.
But there is actually 100GB of space.
Finally,I restart infludb,and it can write new data.

__Environment info:__
OS - Windows Server 2016
InfluxDB v1.8.1

Why I need to restart InfluxDB? Is there anyway ,which it can run normally instead of restarting?

Research direction

Start by reproducing the reported behavior on Windows Server 2016 with InfluxDB v1.8.1: fill the disk, free space, and try writing without restarting. Investigate how disk-space state is handled after cleanup; done means writes resume without requiring an InfluxDB restart.
