Sam Tunnicliffe commented on CASSANDRA-10738:
---------------------------------------------
The post-upgrade sstables for {{system_schema.keyspaces}} you have are
definitely corrupted, I added some additional debug logging to the code that
tries to load the schema at startup and there's a load of junk in there. The
good(ish) news is I've run the same upgrade several times using your
pre-upgrade {{system.schema_keyspaces}} tables and have been unable to
reproduce the corruption. My suggestion then is to force the migration code
that converts from the old to new tables at startup to run again & see if you
get usable tables this time around.
To do that, remove all the corrupt tables from
{{data/system_schema/keyspaces-abac5682dea631c5b535b3d6cffd0fb6/}} and restore
the pre-upgrade tables (the ones in the zip you attached) to
{{data/system/schema_keyspaces-b0f2235744583cdb9631c43e59ce3676/}}. When you
restart the node, it should redo the conversion of the keyspaces table, leaving
in place the other system tables that were already converted. It's possible
there may be other corrupted sstables in the system keyspace, in which case you
should see a similar error as before. If that happens, can you attach the
debug.log, and we'll see where to go from there. It the node does start up
cleanly, you can verify the schema is correct, data accessible and so forth.
Of course, the bad news is that this tells us nothing about how those sstables
came to be corrupted in the first place.
