Normally, there should be an automatic restart. Check if the process exists. If it doesn’t, look at the corresponding directory or the TiKV error log information. The information provided is too limited, so this is as much as I can analyze.
When describing the problem, please follow:

Describe as much effective background information as possible. Many issues may have different suggestions under different scenarios and business contexts. Not explaining clearly will only make it difficult for everyone to help~
Let’s talk about how the previous issues were handled.
What caused the crash? Where are the complete logs?
Is the error that the disk file cannot be found? Is the disk damaged?
The information provided is too little. Based on the error information you provided, I found similar error information:
Phenomenon:
Executing show fields from a reports the following error
Error: Can't create/write to file '/tmp/#sql_419_0.MYI' (Errcode: 17 - File exists): SHOW FULL FIELDS FROM `a`
Solution:
In /tmp, remove the related #sql files.

You can refer to it.
It is recommended to check the data files and log logs.
