I know nothing of LVM, but I think it should still work. What backup tool are you using (dump or tar)? If tar, amanda runs it via the setuid root 'runtar' wrapper, so tar will run as root. amcheck may well fail, IIRC, but amdump should actually work. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
