Hi ! 
I have some issues with my space disk when I start sonarqube, ElasticSearch can’t execute its processes correctly.
Here an example of the es.log file :
2022.01.27 12:08:11 INFO es[][o.e.c.r.a.DiskThresholdMonitor] high disk watermark [90%] no longer exceeded on [TahMKRziTZqRZcT-sLSnxw][sonarqube][C:\sonarqube\data\es7\nodes\0] free: 46.1gb[10%], but low disk watermark [85%] is still exceeded
I made some space on my disk, but it still seems to be not enough :

Is there any information about how much empty space does my disk must have ? Because I can’t make many more place 
If someone have a solution, it would be helpful, thank you ! 
(I put here the sonar logs, because there is also an error (access denied) to a .dll file, but maybe it’s related to the previous error)
