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

This errors occures while uploading OEM agent becuase your filesystem has breached the level to which agent is set.

We had two solutions here:

1. Clear the filesystem, if not perform second step.
2. Change the value of below parameters in emd.properties file in
<AGENT_HOME>/sysman/config/emd.properties.

Parameter before change:
UploadMaxDiskUsedPct=98
UploadMaxDiskUsedPctFloor=95

Parameter After Change:
UploadMaxDiskUsedPct=99
UploadMaxDiskUsedPctFloor=99
./emctl secure agent password
./emctl upload agent
./emctl clearstate agent

Above step will fix the problem and we can upload the agent now:

./emctl upload agent
