I converted my old master backend to a slave backend last night. After some my.cnf wrangling, I got everything up and working - that is, until the flipping power went off for 20 seconds this afternoon. Argh.<br><br>Anyway, now, I 'm having problems with the slave backend connecting. nmap shows ports 6543 and 6544 closed. The slave backend log shows that it connects to the master backend as a slave. The Master frontend log shows nothing of the sort.
<br><br>How can I make sure those ports are open again?<br>
