I'm was running Zimbra NE 5.0 RC2 on RHEL5 in a DRBD/Heartbeat configuration.

The first server upgrade went well, the second wiped out my LDAP data.

Since then, I've tried uninstalling and reinstalling both versions of data and using the zmrestoreldap command....afterwards LDAP never starts again. Even if I go back to RC2, LDAP won't start.

If I use the GUI to try and import the backup, it halts and reports that the admin user already exisits.

Here's the LDAP error....

Failed to start slapd. Attempting debug start to determine error.
bdb(): PANIC: DB_RUNRECOVERY: Fatal error, run database recovery
bdb_db_close: txn_checkpoint failed: Invalid argument (22)
backend_startup_one: bi_db_open failed! (-30978)
bdb_db_close: alock_close failed

Can someone please give me some pointers....I'm at a loss....
