Important: Before starting with below steps, ensure to validate the stored buckets
Steps:
1. Run the below command on both affected node.
Note: This might take a while for the command to finish running. The results of the command will be saved in the /tmp/validate.txt file:
cd /usr/lib/loginsight/application/sbin ./validate-bucket --validate > /tmp/validate.txt
2. Once the validate is completed refer the /tmp/validate.txt and make sure no corrupted buckets. If any follow Phase 1 of the action plan, if there are no corrupted buckets follow Phase 2.
Phase 1:
1. stop log insight
/etc/init.d/loginsight stop
2. list the buckets, Look for the guid of the old buckets by timestamp
/usr/lib/loginsight/application/sbin/bucket-index show
3. Run the following command to delete a bucket
/usr/lib/loginsight/application/sbin/bucket-index delete [BUCKET-ID]
4. start loginsight
/etc/init.d/loginsight start
The "./validate-bucket --validate" would reveal if there are any corrupted buckets remove those instead of looking for the oldest buckets.
Phase 2:
1. Deploy a new Aria Operations for logs node following the steps outlined in below document.
https://docs.vmware.com/en/VMware-Aria-Operations-for-Logs/8.18/Getting-Started-Operations-for-Logs/GUID-950D4050-ABA2-4375-A381-47187DC8C674.html2. Once you have the new Aria Operations for logs node deployed, the next is to import the buckets from old node into the new one without losing any data. Steps below.
1)ssh to Log Insight you want to import events from and go to “/storage/core/loginsight/cidata/store” – this is where the data buckets live.
2)run “service loginsight stop” to stop Log Insight. Ensure the service has stopped by running “service loginsight status”.
3)copy the buckets you want to import to target Log Insight - the destination directory must be the same; i.e. “/storage/core/loginsight/cidata/store”
4)ssh to Log Insight that will be importing the events and stop the service by running “service loginsight stop”. Ensure the service has stopped by running “service loginsight status”.
5)run “/usr/lib/loginsight/application/sbin/bucket-index add <bucket_id>”
6)Repeat the step above for all the copied buckets.
3. Ensure you complete the steps for both the current worker nodes to new nodes.
4. Once the above is completed. Join the 2 new nodes to the existing Deployment following the below document
