Have you tried using the "filter" directive in the /etc/lvm/lvm.cnf to force vgscan to ignore the /dev/hdd device? In my config it ignores /dev/cdrom which does not actually point to my real cdrom on /dev/hdc and it still has no issues, but it may be worth a shot anyway. Also, it might be worth strace-ing the vgscan to see what happens when it tries to fstat the /dev/hdd device: strace vgscan >& output.log -dave --- Christophe Nowicki <cscm@meuh.dyndns.org> wrote: > Hi all, > > I'am running Debian GNU/Linux "sarge" with Linux > 2.4.26, LVM version > 1.0.8 (lib lvm-common 1.5.16). > > My server has 3 IDE hard drives when I plug a ide > cdrom on /dev/hdd, > vgscan can not find my active volume. > > Here is my dmesg output without the cdrom ide plug > in : > [...] > ide: Assuming 33MHz system bus speed for PIO modes;
