I set up replication between 2 cores on one master and 2 cores on one slave. Before doing this the master was working without issues, and I stopped all indexing on the master.
Now that replication has synced the index files, an .FDT field is suddenly missing on both the master and the slave. Pretty much every operation (core reload, commit, add document) fails with an error like the one posted below. How could this happen? How can one recover from such an error? Is there any way to regenerate the FDT file without re-indexing everything? This brings me to a question about backups. If I run the replication?command=backup command, where is this backup stored? I've tried this a few times and get an OK response from the machine, but I don't see the backup generated anywhere.
