Hi Michal, =20

   Those ids are stored in system.schema=5Fcolumnfamilies as part of each=
 column family metadata. Have you tried deleting SSTable files from <cass=
andra-data-path/system/schema=5Fcolumnfamilies on failing nodes and resta=
rting them=3F That should re-fetch schema, also you can try 'nodetool res=
etschema' command which does just that. =20

Best Regards
