[linux-lvm] Problem doing basic LVM functions

[Ricardo Sanchez]

Toby

Thanks for the reply. I am not using nbd nodes...the kernel started throwing
out those messages I have never worked with nbd nodes. How can I destroy the
nbd nodes? I just want to start all over again but can't. Every time I try
to do lvm functions, it hangs on those messages.

Thanks

Ricardo

Are you trying to use nbd nodes in LVM?

I had the same problem using nbd & LVM. I first had to destroy & recreate
the nbd nodes.  I put each nbd node into a single disk md, & used the md
nodes in my pv & vg. 

Been working fine that way for several months now, although running locate
to find a file would crash the system, so I removed the slocate rpm.
