Hi, it's my story.
I have two 4.0.14 mysql server on one machine with win XP Professional
polish version.
First acts as master: on port 3300
Second acts as slave: on port 3301

So i have noticed this things.
I start replication with master and slave:
1)
Master is running ...
---------------------------------------------------
Slave is running ... and at console can i see:
030804 22:55:36 InnoDB: Started
030804 22:55:36 Slave I/O thread: connected to master
'i***@127.0.0.1:3300', r
eplication started in log 'FIRST' at position 4
030804 22:55:36 Slave SQL thread initialized, starting replication in log
'FIRS
T' at position 0, relay log '.\hq-relay-bin.001' position: 4
mysqld-max-nt: ready for connections.
Version: '4.0.14-max-nt' socket: '' port: 3301
---------------------------------------------------
That is ok.
3) checked master data dir:
hq-bin.001
hq-bin.index
4) checked slave data dir:
hq-relay-bin.001
hq-relay-bin.index
master.info
relay-log.info
5) I stopped slave - shutdown nicely.
6) I stopped and started master 3 times.
7) I checked master data dir and i can see:
hq-bin.001
hq-bin.002
hq-bin.003
hq-bin.004
hq-bin.index
8) I started master.
9) master data dir:
hq-bin.001
hq-bin.002
hq-bin.003
hq-bin.004
hq-bin.005
hq-bin.index
10) I started a slave:
030804 23:07:36 InnoDB: Started
030804 23:07:36 Slave I/O thread: connected to master
'i***@127.0.0.1:3300', r
eplication started in log 'hq-bin.001' at position 79
030804 23:07:36 Slave SQL thread initialized, starting replication in log
'hq-b
in.001' at position 79, relay log '.\hq-relay-bin.001' position: 116
mysqld-max-nt: ready for connections.
Version: '4.0.14-max-nt' socket: '' port: 3301
11) I stopped slave (master is still runing):
12) I started slave again:
030804 23:09:17 InnoDB: Started
030804 23:09:17 Slave I/O thread: connected to master
'i***@127.0.0.1:3300', r
eplication started in log 'hq-bin.005' at position 79
030804 23:09:17 Slave SQL thread initialized, starting replication in log
'hq-b
in.005' at position 79, relay log '.\hq-relay-bin.002' position: 489
030804 23:09:17 next log error: -1 offset: 19 log:
030804 23:09:17 Error reading relay log event: Error purging processed log
030804 23:09:17 Could not parse relay log event entry. The possible reasons
are
: the master's binary log is corrupted (you can check this by running
'mysqlbinl
og' on the binary log), the slave's relay log is corrupted (you can check
this b
y running 'mysqlbinlog' on the relay log), a network problem, or a bug in
the ma
ster's or slave's MySQL code. If you want to check the master's binary log
or sl
ave's relay log, you will be able to know their names by issuing 'SHOW SLAVE
STA
TUS' on this slave.
030804 23:09:17 Error running query, slave SQL thread aborted. Fix the
problem,
and restart the slave SQL thread with "SLAVE START". We stopped at log
'hq-bin.
005' position 79
mysqld-max-nt: ready for connections.
Version: '4.0.14-max-nt' socket: '' port: 3301
13) In slave data dir:
hq-relay-bin.003
hq-relay-bin.index
master.info
relay-log.info
THIS IS BUG ???
Now my slave is runnung, but does'nt do a replication.
14) stop slave and running it again.
030804 23:12:00 InnoDB: Started
030804 23:12:00 Failed to open the relay log
(relay_log_name='.\hq-relay-bin.00
2', relay_log_pos=489
030804 23:12:00 Could not find first log during relay log initialization
030804 23:12:00 Failed to initialize the master info structure
mysqld-max-nt: ready for connections.
Version: '4.0.14-max-nt' socket: '' port: 3301
Right, in slave data dir isn't that file, it is deleted by mysql server wich
is running as slave, WHY ??
IS that BUG, what should i do ?
LOAD DATA FROM MASTER ?? or sync again slave tables with master tables ??
Best regards, irek
