How to solve jenkins 'Disk space is too low' issue?

Question

I have deployed Jenkins in my CentOS machine, Jenkins was working well for 3 days, but yesterday there was a Disk space is too low. Only 1.019GB left.

Answer 1

Beside above solutions, there is a more "COMMON" way - directly delete the largest space consumer from Linux machine. You can follow the below steps:

1. Login to Jenkins machine (Putty)
2. cd to the Jenkins installation path

Using ls -lart to list out hidden folder also, normally jenkin installation is placed in .jenkins/ folder

[xxxxx ~]$ ls -lart

drwxrwxr-x 12 xxxx 4096 Feb 8 02:08 .jenkins/

3. list out the folders spaces

Use df -h to show Disk space in high level

du -sh ./*/ to list out total memory for each subfolder in current path.

du -a /etc/ | sort -n -r | head -n 10 will list top 10 directories eating disk space in /etc/

4. Delete old build or other large size folder

Normally ./job/ folder or ./workspace/ folder can be the largest folder. Please go inside and delete base on you need (DO NOT delete entire folder).

rm -rf theFolderToDelete
