[Linux-cluster] qdiskd locks cluster

[Stepan Kadlec]

hi,
I am running cluster 2.03.08.
after adding qdisk feature to twonode cluster, it somehow locks entire 
cluster. without qdisk it runs ok.

initialization log:

after this, all cluster tools just hang - cman_tool nodes, clustat, ...

and cluster processes are in locked state:

13124 ?        Ssl    0:00 /sbin/ccsd -4
13129 ?        SLl    0:00 aisexec
13154 ?        Ss     0:00 /sbin/groupd
13157 ?        SLs    0:00 /sbin/qdiskd -Q
13162 ?        Ss     0:00 /sbin/fenced
13167 ?        Ss     0:00 /sbin/dlm_controld

any ideas howto fix that?
thanks stepan.
