前言

jenkins 有 master 跟 slave,运行久了这些节点都有可能磁盘满了。

1. 查看系统总体存储情况

[root@ecs-bj4-eccjenkinsslave-androidcicd devops]# df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        7.8G     0  7.8G   0% /dev
tmpfs           7.8G   12K  7.8G   1% /dev/shm
tmpfs           7.8G   68M  7.7G   1% /run
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/vda1        69G   45G   22G  78% /
tmpfs           1.6G     0  1.6G   0% /run/user/0
tmpfs           1.6G     0  1.6G   0% /run/user/1001

2. 从根目录开始一层层查找哪个目录占用的磁盘异常

通过层层排查,我们来到了 /var/lib/jenkins/jobs/ 目录,这个目录一看就是 jenkins job 构建产物的目录
[root@ecs-bj4-eccjenkinsslave-androidcicd jobs]# du -h --max-depth=1
800K ./Arv_Datalink_Manage_Test2
16M ./OTP_Runner
40M ./Arv_Koala_Admin_Dev

972K ./Arv_SOUL_Test1
55M ./iOS_JoymoClient_Test

812K ./Arv_Datalink_Work_Pre

36M ./iOS_JoymoOperation_Test
135M ./Android_joymoclient_Test
492M ./IOT_Android_GatewayApp_Test
452K ./SpringProject_Ecs
13G .

3. 通过上面查找出占用比较多的 job,到 jenkins 控制台查看配置

在 job 的配置里面有个丢弃策略,这边可以根据自己的情况调小点。

扩容

扩容的话需要调整相对于的工作目录

master

配置文件路径:/etc/sysconfig,调整下 JENKINS_HOME 参数

## Path:        Development/Jenkins
## Description: Jenkins Automation Server
## Type:        string
## Default:     "/var/lib/jenkins"
## ServiceRestart: jenkins
#
# Directory where Jenkins store its configuration and working
# files (checkouts, build reports, artifacts, ...).
#
JENKINS_HOME="/var/lib/jenkins"

## Type:        string
## Default:     ""
## ServiceRestart: jenkins
#
# Java executable to run Jenkins
# When left empty, we'll try to find the suitable Java.
#

调整完重启下服务

service jenkins restart

slave

新加了一块盘挂载到 /workspace 目录,相对于的 slave 的工作目录需要调整。

[root@ecs-test-jenkins-slave jenkinsHome]# df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        7.8G     0  7.8G   0% /dev
tmpfs           7.8G     0  7.8G   0% /dev/shm
tmpfs           7.8G  137M  7.7G   2% /run
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/vda1       148G   42G  100G  30% /
tmpfs           1.6G     0  1.6G   0% /run/user/0
/dev/vdb1        50G   13G   35G  26% /workspace
tmpfs           1.6G     0  1.6G   0% /run/user/1001
tmpfs           1.6G     0  1.6G   0% /run/user/1000
