Welcome to the community forum! Does this happen for all projects, or only one specifically?

Thanks for your reply, it is happening for all projects

Ok, please give us a bit more logs from ce.log. Is there any caused by statements?

Hi Team,

Please find the attached ce.log file, I am using scanner process from Jenkins and from scanner from local system both are getting same issue, can you please check into it.

Thanks & Regards,

Thanks for the fast reply. In the log, we can see this line:

2020.11.17 20:08:50 ERROR ce[][] index [projectmeasures], type [auth], id [AXXFXCgSRM_uIcmAg79p], message [ClusterBlockException[blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];]]

That means that the elasticsearch index have been locked in read-only mode, and SonarQube can’t write anymore. That means you reached 95% used disk space on where the /data/ folder is located. Please increase the available free disk space, and restart SonarQube. The elasticsearch will be switched back to read-write during startup.

Hi Team,

Thanks for your reply, Can someone please suggest me how to free up disk space in /data/ folder in sonarqube server.

Thanks & Regards,

++ I have installed sonarqube server in Linux machine, please suggest me how to freeup space.


Well first you have to figure out on which hard drive disk is located the sonarqube/data folder.

Something like df -h may help you to see if the /data folder is located on a particular drive, and what is the remaining space for that disk. Then i suggest you to have a look at this kind of page to guide you.

Hi Team,

My size is around 800mb and disk space is filled with 95%, so i need to remove anything from the file or i need to increases the disk space , i am attaching the Screenshot please check.


Hi, yes you need to free some space, or increase the disk size.
