AI-generated summary

The exception occurs due to insufficient disk space for message storage. Two possible solutions are to modify the disk space warning ratio to only trigger an error when disk usage exceeds 99% and to change the message storage address to a disk with more available space.

This exception occurs mainly due to insufficient disk space for message storage. In this case, the following two operations can be performed:

Modify the disk space warning ratio
Add set "JAVA_OPT=%JAVA_OPT% -server -Xms512m -Xmx512m -Xmn128m -Drocketmq.broker.diskSpaceWarningLevelRatio=0.99" to the runbroker.cmd file to trigger an error only when disk usage exceeds 99%. The fundamental solution is to ensure that disk space never exceeds 90%.
Change the message storage address to a disk with more remaining space
Add set "JAVA_OPT=%JAVA_OPT% -Duser.home=D:/mqs/rocket-mq" to the runbroker.cmd file.
