Attempting to reindex your backups, within Jetbackup, may result in an error similar to the following:
[August 12, 2020 05:43:53 PM -0300] Indexing account "account" ... [August 12, 2020 05:43:53 PM -0300] [ERROR] interrupted at shutdown
No suitable servers found (set `serverSelectionTryOnce`): [connection closed by calling ismaster at 'localhost: 27217']
This can sometimes occur if the mongod service is down.
To resolve the issue, you will want to restart the mongod service with the following:
systemctl restart jetmongod
For CentOS systems, you can run the following to restart the mongod service:
service jetmongod restart
