Hi List, I had a database with a 8 Mb pg_dump file with 1.7 Gb in PG_DATA. I dropped the database and tried to recreate the db with this step: psql template1 < data.sql All tables and all data was restored and to help accessing the db I tried to vacuum analyze it, yielding this error message: vacuumdb -z miwabar PANIC: open of /var/lib/pgsql/data/pg_clog/0000 failed: Keine Berechtigung server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. connection to server was lost vacuumdb: vacuum miwabar failed The panic message with -v gave PANIC: read of clog file 0, offset 16384 failed: Erfolg which lead me to the mailing-list archive and the following fix: dd bs=32k count=1 </dev/zero >/var/lib/pgsql/data/pg_clog/0000 1+0 records in 1+0 records out afterwards my vacuum works. Had I done the right thing? Should I have expected this error? -- Peter ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to majordomo@xxxxxxxxxxxxxx
