Re: [linux-lvm] Error on vgscan & lvremove



Heinz,

I verified these two issues as commented below;

worked w/o delimiters like

        ls /dev/*/group | sed 's/group//' | xargs rm -r ; vgmknodes

Yes, worked with "make distclean".

For the backward compatibilty I will try later.

One more question related with activating PV,

Of course I could make them active after removing the volume and recreating
it.
As you can notice on the attached log VG is ok,  How could I make these PVs
active
w/o removing the volume?

Did it corrupt the VGDA? any way to recover it?
(PS: you can notice TWO "volDisk" group in the following "vgdisplay", should
be
        volDisk  & volDisk2 ???)

Thanks again,

Bo
