[DiskThresholdMonitor] high disk watermark [90%] exceeded on

Hi all,

Currently I am using SonarQube with MSSQL database. I tried to upgrade it into version So, I downloaded all the configurations as zip file and copied all the configurations from old SonarQube server, stopped it and start the new server. But It didn’t start as I expected. Then I checked the logs and found these,

2021.11.29 23:54:25 WARN es[][o.e.c.r.a.DiskThresholdMonitor] high disk watermark [90%] exceeded on [gAyZVIHES0qux1PhvIa1Tg][sonarqube][C:\SonarQube\sonarqube-\data\es7\nodes\0] free: 19.8gb[9.9%], shards will be relocated away from this node; currently relocating away shards totalling [0] bytes; the node is expected to continue to exceed the high disk watermark when these relocations are complete

Please suggest me a solution for this. Thanks.


Hi Khopi,

Welcome to the community!

This is about free diskspace on the server hosting SonarQube. And while 19.8gb would seem to be plenty of free filespace, unfortunately, this works on percentages. So you’ll need to free up a little more filespace - I think the 10% free mark is what you need to hit. And then restart SonarQube. The indices will automatically be unlocked when you do.


Hi @ganncamp,

Thank you very much.
