EMD upload error: Upload was successful but collections currently disabled - disk full

Solution:
-----------

<AGENT_HOME>/bin/emctl stop agent
<AGENT_HOME>/bin/emctl clearstate agent

cd <AGENT_STATE>/sysman/emd/upload
ls *.xml | wc -l


- Delete any pending upload files from the agent home

rm -r <AGENT_STATE>/sysman/emd/upload/*
rm <AGENT_STATE>/sysman/emd/lastupld.xml  

After deleting the files from upload re-start the agent and verify, if still did not help, please process the below.

- If needed, the values of the following parameters can be increased in the emd.properties file:



vi $AGENT_HOME/sysman/config/emd.properites


Below are the default values

UploadFileSize=2048
UploadMaxBytesXML=50
UploadMaxDiskUsedPct=98

Increase the above values as

UploadMaxBytesXML=60
UploadMaxDiskUsedPct=99 (Default value is 98)

<AGENT_HOME>/bin/emctl start agent

<AGENT_HOME>/bin/emctl status agent
