We did a percona backup and everything went fine. But after starting slave, we got the below error:
Slave I/O Running : No
Last_IO_Error : Got fatal error 1236 from master when reading data from binary log: ‘Could not find first log file name in binary log index file’
We checked the max_allowed_packet configuration and it is same in both master and slave.
The Relay_Master_Log_File ( which we got from percona backup ) is existing in master .
Now what could be the reason for the issue? Please help us to resolve the issue .
