Description
When nodes are starting, their SSL keys and certificates are synchronized with the other cluster nodes to ensure that all nodes use the same keys/certificates.
Due to an error in our implementation, the key/certificate files can briefly disappear during this synchronization process; if by chance another process tries to access these files at the same time, node startup will fail with a “no such file or directory” error message in the exainit log.
Workaround
Retry starting the node(s); this is a timing issue, so it only occurs sporadically and unpredictably.
Fix
File synchronization updates the SSL keys/certificates atomically. Node startup does not sporadically fail.
