Create Application shows : Unable to carry out the operation. No updates have been made - Log File Shows: Errcode: 28 - No space left on device

Products

• CA API Developer Portal

Issue/Introduction

We upgraded portal version from 3.5 -- 5.0.CR1 and then to 5.0.2

We are unable to add API to an application

Added an new API says (xyz) to plan "Gold" and while assigning the API to an application getting this error :

ERRORS(1) 

* Request failed with status code 500

 

Environment

Release : 5.0.2

Component : API PORTAL

Cause

mysql is running on the same vm as the portal and the /tmp partition is configured for 512 MB (default). Which is not enough to manage the mysql request.

Resolution

Troubleshooting 

1. Prepare to use dispatcher and portal_data container logs for monitoring the test and check errors . 

docker ps  , check the container id for dispatcher and portal_data

for Dispatcher container Id , copy and paste into the following command:

docker inspect <container_id> |grep -i log

from the output, copy the LogPath and you can then use it on a tail command like :

tail -f “/apps/dockermount/containers/……….json.log

2.  From the portal server  df -h and check  /tmp , if set to 512mb and % space used. 

Due error message is a mysql Errcode: 28 - No space left on device :

which means there is not enough space left on the device.

** we recommend a partition size of 16GB for /tmp.

3. Two options :  Increase the partition size or change the /tmp directory to other partition with more free space. issue is resolved.
