[Linux-cluster] lvextend hangs up

[Diamond Li]

after I reboot clvmd, it works now. but after a while, all lvm
commands hung again. So I have to reboot machine,  unfortunately, OS
hung as well, I have to press "reset" button.

I did run lvmconf --enable-cluster, clvmd is not stable or I missed something?
