[Linux-cluster] clvmd issue with RH/Centos 6.9 update

[Andrea Costantino]

Hello fellow cluster guys,

 

I just upgraded my CentOS cluster to 6.9 and after a node reboot I
discovered that the clvm functionality was broken.

 

Long story made short, I tracked it back to clvmd process being hung with
one CPU stuck.

 

The quick and dirty solution was to rollback kernel to version
2.6.32-642.15.1.el6.x86_64, and the problem did not happen anymore.

 

Anyway after opening a bugzilla, RH guys pointed me to the real issue, that
is a libqb thread issue.

 

The bug (containing the temporary fix, waiting for the next packages
upgrade) is tracked here:

 

https://bugzilla.redhat.com/show_bug.cgi?id=1440160

 

Hope it helps others.

 

Ciao,

A.
