Hi, In case if you see (page content is corrupted) and after that upgrade your version to 2.6 then it's possible that your persistence is still broken.
The most simple way here is cleaning your PDS (work/db) directory before the upgrading to 2.6. In case if data is important then you also can try to do next: 1)Stop the cluster 2)Remove only index.bin files from work/db/<NodeName>/<cache_name>/index.bin. 3)Restart the cluster 4)Wait for the message that indexes were rebuilt in Ignite log. In case if it will not help then only cleaning of PDS will help. BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
