STEPS:
1. delete the Swarm elasticsearch index (if a Search Feed had been configured)
2. reformat the Swarm volumes
3. reset the CSN's logs and other data
4. reset the CSN configuration backups
1. Delete the Swarm elasticsearch index
2. Reformat the disks
- attach a keyboard and monitor to a Swarm storage server.
- select 'System Control' -> 'Stop Storage Processes'
- select 'Disk Volumes' -> 'All' -> press F to Format -> accept confirmation(s)
- repeat with each server leaving the storage processes off (so that there is no replication to the newly formatted disks)
- once all storage server disks have been formatted and storage processes been turned off, on all storage servers, select 'System Control' -> 'Reboot' (watch and make sure they PXEboot)
3. Reset the CSN's logs and other cluster-specific data
- log into the CSN via SSH
- remove any logs in /var/log/caringo/ that you no longer desire. You may want to keep them for history purposes, but likely you want fresh logs for the fresh cluster. I suggest moving at least the cr.log (if present), castor.log, and scspproxy.log
- on older CSN's that included the Content Router, you may delete any data in /u01/
- remove any rrd files in /var/opt/caringo/StorageReporter/data/
4. Reset the CSN backups
- create a new backup manifest UUID by removing the uuid in:
/var/opt/caringo/csn/backup/manifest/.bootstrap
- remove references to the old backups by removing the savesets files in:
/var/opt/caringo/csn/backup/manifest/
- reboot your CSN.
- Log into the CSN UI. Make a manual backup, 'Cluster Services' -> 'Backup and Restore' -> 'Create Backup'. You should see a new backup manifest UUID.
