Remember once: when prompted java.io.IOException Jenkins building: No space left on device

Question 1:

When Jenkins with hair version, suggesting java.io.IOException: No space left on device hard disk storage is not enough.

the reason:

Jenkins in discarding the old building of the policy is not configured, as shown below (I have configured):

Method:

• First locate the disk where large files, the beginning I used df -h, found it impossible to accurately locate, then prompts colleagues with ncdu (installation way: yum install ncdu);
• Also, look for error prompt files directly went to the local copy path, then ncdu [path]; then delete build package

Note: Jenkins when using scp courier jar package, use the network address today due to the operation and maintenance of small partners to restrict access to port 22, leading to ssh: connect to host 140.143.29.146 port 22: Connection timed out exception.
