             Summary: Invalid cross-device link error if cdcWalPath and walArchivePath point to a different file system partitions
                 Key: IGNITE-16541
                 URL: https://issues.apache.org/jira/browse/IGNITE-16541
             Project: Ignite
          Issue Type: Improvement
            Reporter: Ilya Shishkov


Currently, if CDC is turned on and {{cdcWalPath}} and {{walArchivePath}} point to a different file system partitions, server node fails on a first attempt to archive segment, but not during a startup.
Because cluster may be under load, in order to prevent data loss or corruption we should implement fail-first approach for this case.  Server node should check {{cdcWalPath}} and {{walArchivePath}} during the startup, and prevent further starting if they point to different file system partitions.
