Resolving the issues while migrating the packages between AEM instances

This is a common scenario to migrate the packages between AEM instances, some times we may face issues while building or uploading the big packages.

This post explains the details to resolve the issues observed while building or uploading the big packages between AEM instances

java.io.IOException: No space left on device while building the package:
The "java.io.IOException: No space left on device" error will be thrown while building big packages in the AEM server without having sufficient space available in /tmp folder.

To fix the issue-
Option1
Add additional space to the /tmp folder

Option2
Point to the custom tmp folder in server startup file - make sure the aem user is owning the custom tmp folder

CQ_JVM_OPTS='-server -Xmx8192m -XX:MaxPermSize=512M -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/app/aem/crash -Djava.awt.headless=true -Duser.timezone=US/Central -Djava.io.tmpdir=/app/tmp'

Error while uploading/Installing the package:
Sometimes uploading a package on my AEM server via Package Manager is keeps loading it for a long time and then fails without any exception. This scenario is observed in most of the cases while uploading the packages with a big size.

To fix the issue:
Upload and install the package via Curl command - Execute the command from the folder where the packages are available

curl -u admin:admin -F "file=@test_package-1.0.zip" -F "name=test_package-1.0" -F force=true -F install=true http://localhost:4502/crx/packmgr/service.jsp --progress-bar -o upload.txt
