I have no experience with SBD on SLES but I know that handling of
the<br>
logging verbosity-levels has changed recently in the upstream-repo.<br>
Given that it was done by Yan Gao iirc I'd assume it went into SLES.<br>
So changing the verbosity of the sbd-daemon might get you back<br>
these logs.<br>
And of course you can use the list command on the other node<br>
to verify as well.<br>

<div>I have requested help from SuSE guys, but they didn't give
me any valuable feedback yet now!</div>

</div>
<div><br>
</div>
<div>Below are some screenshots to explain what i have
encountered.</div>
<div>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br>
</div>
<div><br>
</div>
<div>on a SuSE11 SP4 HAE cluster, i run the sbd test command
as below:</div>
<div><img size="57698" style="max-width: 100%;" src="cid:167d021ad3acb971f161"><br>
</div>
<div><br>
</div>
<div>then there will be some information showed up in the local
system message log<br>
</div>
<div><img size="161176" style="max-width: 100%;" src="cid:167d021ad3bcb971f162"><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>on the second node, we can found that the communication is
normal by <br>
</div>
<div><img size="148274" style="max-width: 100%;" src="cid:167d021ad3bcb971f163"><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>but when i turn to a SuSE12 SP3 HAE cluster, ran the same
command as above:</div>
<div><br>
</div>
<div><img size="58918" style="max-width: 100%;" src="cid:167d021ad3ccb971f164"><br>
</div>
<div><br>
</div>
<div>I didn't get any response in the system message log.</div>
<div><img size="11062" style="max-width: 100%;" src="cid:167d021ad3ccb971f165"><br>
</div>
<div><br>
</div>
<div>"systemctl status sbd" also doesn't give me any clue on
this.</div>
<div><br>
</div>
<div><img size="48638" style="max-width: 100%;" src="cid:167d021ad3ccb971f166"><br>
</div>
<div><br>
</div>
<div>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</div>
<div><br>
</div>
<div>What could be the reason for this abnormal behavior? Is
there any problems with my setup?</div>
<div>Any suggestions are appreciate!<br>
</div>
<div><br>
</div>
<div>Thanks!</div>
