Hi, we have an cluster with 7 machines with a SAN. We are using them to provide virtual machines, so we are using clvmd.
At some point we are unable to access any of the pv/lv/vg tools. They are all
stuck. From stracing them i've come to the conclusion that they are waiting
for clvmd.
Has anyone been in this situation?
Thanks for any help,
Nuno Fernandes
