loosing data, of course?

Thanks,

Stephan,

recent LVM versions have a pvresize command, which can add the space of
a grown partition/device to a physical volume stored in that partition.

You can't combine seperate devices (like 2 different disks) this way.

If hdd is a free disk, just run pvcreate on it and use vgextend to add it
to one of your existing volume groups.

Heinz,

well yes, after doing a makewhatis i found the vgextend command and that 
was absolutely what I was looking for.

I also followed som eadvice from this list and excluded autoconfig.h 
from liblvm.h and compiling went smoothly on my RH 7.2.93 box. Just if 
anybody wanted to know...

Thanks,
Stephan
