Hello Experts,
I'm New to this mail lists.
Pls kindlyforgive me if this mail has disturb you!
Our Company recently is evaluating the usage of the SuSE HAE on x86
platform.
Wen simulating the storage disaster fail-over, i finally found that
the SBD communication functioned normal on SuSE11 SP4 but abnormal on
SuSE12 SP3.
I have no experience with SBD on SLES but I know that handling of the
logging verbosity-levels has changed recently in the upstream-repo.
Given that it was done by Yan Gao iirc I'd assume it went into SLES.
So changing the verbosity of the sbd-daemon might get you back
these logs.
Yes, I think it's the issue. Could you please retrieve the latest
maintenance update for SLE12SP3 and try? Otherwise of course you could
temporarily enable verbose/debug logging by adding a couple of "-v" into
"SBD_OPTS" in /etc/sysconfig/sbd.
But frankly, it makes more sense to manually trigger fencing for example
by "crm node fence" and see if it indeed works correctly.
And of course you can use the list command on the other node
to verify as well.
The "test" message in the slot might get overwritten soon by a "clear"
if the sbd daemon is running.

The SBD device was added during the initialization of the first
cluster node.
I have requested help from SuSE guys, but they didn't give me any
valuable feedback yet now!
Below are some screenshots to explain what i have encountered.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
on a SuSE11 SP4 HAE cluster, i run the sbd test command as below:
then there will be some information showed up in the local system
message log
on the second node, we can found that the communication is normal by
but when i turn to a SuSE12 SP3 HAE cluster, ran the same command as
above:
I didn't get any response in the system message log.
"systemctl status sbd" also doesn't give me any clue on this.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What could be the reason for this abnormal behavior? Is there any
problems with my setup?
Any suggestions are appreciate!
Thanks!
Regards
FuLong
