Out of Space Issues

If the nexus server drops below 4G you will see in the logs the DB has moved to read only

The only known approach so far is

• login to the docker container as root sudo docker exec -u 0 -it nexus /bin/bash
• edit the nexus.vmoptions file located in cd /opt/sonatype/nexus/bin/
• or vi /opt/sonatype/nexus/bin/nexus.vmoptions
• add or uncomment the following line -Dstorage.diskCache.diskFreeSpaceLimit=1024
• exit docker bash
• restart nexus sudo docker restart nexus
• the Nexus is now in an editable state and artifacts can be removed in an effort to claim back space

* edit file and remove # from last line

• sudo docker exec -u 0 -it nexus vi /opt/sonatype/nexus/bin/nexus.vmoptions
• restart nexus sudo docker restart nexus

Once you have deleted number of artifacts, (start with largest first, to get going) you must run the Compact Blob store task to reduce space

• Go to the tasks list under the Admin tab (you must be logged in)
• run the Compact process, as its only set to weekly due to length of execution
• This may affect the artifactory being written to (it has performance implications)

• on success run the df -h command and verify that the disk space is > 3G
  • /dev/nvme0n1p1 60G 53G 7.5G 88% /

Nexus allows the execution of groovy scripts on the repo, which is useful to find largest files etc

but this must be enabled

Reference Sonatype Support page

• Edit $data-dir/etc/nexus.properties.
• Add the following on a new line, making sure the file is saved with an ending new line and with the original file permissions:

• Restart NXRM to pick up the property change.

The artifactory needs to ensure that older redundant builds are periodically cleaned out, otherwise it will quickly fill up. SnmpManager is a large war file on its own.

To do this we use the Clean Up Policy Manager, example configuration deletes after 15 days
