<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">I have deployed my application to three nodes with mnesia in standalone mode. I have three tables, one of which recently changed. I have all three upgraded with the correct table schema and running fine in standalone mode. When I switch them to clustered I receive the following error</span><p style="font-family:arial,sans-serif;font-size:13px">
{merge_schema_failed,</p><p style="font-family:arial,sans-serif;font-size:13px"> "Bad cookie in table definition <the recently changed table?:</p><p style="font-family:arial,sans-serif;font-size:13px">
<br></p><p style="font-family:arial,sans-serif;font-size:13px">I cannot determine what is causing this. I can delete the mnesia directory and re-start and it works fine. However, this is obviously not an acceptable solution for a production deployment.</p>
<p style="font-family:arial,sans-serif;font-size:13px">What could cause this error? All three nodes have the exact same schema and my understanding was that this was the cause of this issue. I think this just is the result of a newbie not understanding the purpose of the table cookie.</p>
