I’ve got this on one of my mysql powerdns replication slaves. I restored the server from another slave and forgot to change the server-id in my.cnf.
hope it saves someone sometime …

Make sure your time on the BES server is correct …

open terminal ( of course )

# get drive name
$ drutil status
#un mount
$ diskutil unmountDisk /dev/disk1
#make iso
$ dd if=/dev/disk1 of=file.iso bs=2048
#test iso
$ hdid file.iso


kudos to the original post
