works the IO load is moderate (about 20% or less). But when it hangs it
jumps up to 100% on one or more cores.
I ran into similar issues when attempting a pvmove with clustered VG's under CLVMD. I had to change the clustered VG to non-clustered and then I could do the pvmove. You didn't mention clusters, but thought I would share my experiences.
