Some lvm tools/packages have replaced others that don't have lvm in the name, so maybe that's what you have seen. They aren't solely used for LVM-related things, though

The box is a new Armari system with an Asus P7P55D motherboard and a Samsung Spinpoint F3 1TB SATA II hdd. Having read the thread, there are three things that come to my mind: 1) Have you tried to read from the disk at block zero, i.e. try something like dd if=/dev/sda of=/dev/null bs=512 count=1024 This should read half a megabyte from the disk and for your hardisk be finsihed as soon you release the enter key ... Errors? and messages in dmsg? 2) The dmesg-output you mailed contains a call-trace about calgary. AFAIK calgary is a IOmmu. Have you tried to disable it (try something like appending iommu=none to your kernel commandline). Have you looked for a bios upgrade? maybe you can get rid of the broken bios messages this way. 3) A long time ago, there was a bios option for bootsector-protection, I've never tried this, and I also don't have any idea whether linux sees that in any way. If there is such an option, disable it. Greetings Alex

When is a disk not a disk? According to Dell: when you source it from a 3rd-party. http://lists.us.dell.com/pipermail/linux-poweredge/2010-February/041274.html http://tinyurl.com/yer7n9o Stroller.

It's not wrong - it was just unexpected for me. I did, but I think I'll revert to just a single boot partition. The other two little ones were for other distros' boot directories, so that installing them wouldn't clobber my Gentoo boot - the latest Ubuntu uses grub-2, for instance, which I don't want mixed with grub-1. Is yours a 1-Terabyte drive? Yes. Vast overkill for what I need it for, but it seems normal nowadays. -- Rgds Peter.

LVM can't just turn up with a profile change, you need to allocate partitions to it, create volume groups, create volumes in them, put filesystems on the volumes and so on. It doesn't just happen. /dev/root is just a symlink to the real device containing the root partition. ISTR it came in with openrc. -- Neil Bothwick signature.asc Description: PGP signature
