As a guess, I suspect the permissions on the files are messed up, and the user running running the -z is not the same user you are using to do a full rebuild. I'm using the same user to do both rebuilds. What we found is that with the -z option, no record is found. It returns 0 for everything. ==================== exporting authority ==================== 0 Records exported: 0 ==================== REINDEXING zebra ==================== ==================== exporting biblio ==================== 0 Records exported: 0 ==================== REINDEXING zebra ==================== Is there any other possible reason why that is happening?
