I have been attempting to get LVM set up on a freshly-installed Slackware 8.0 system (custom 2.4.18 monolithic kernel, LVM 1.0.3, no kernel patches). It works fine in multi-user mode, it works fine in single-user mode, however I set up the single-user init script like this: (/ is mounted read only at this point) mount -o remount,rw / vgscan vgchange -a y mount -o remount,ro / (stock Slackware fsck and mount bits) The only volume group I have contains one physical volume (/dev/sdb, on an Adaptec 7xxx controller). For some reason, vgscan doesn't pick up the volume group. The exit code is 0, and looking at the debug output it hits /dev/sdb and spits out the same messages as when it hits all the other devices. As an experiment I put a call to sulogin before the vgscan and tried running it by hand; same thing happened. I tried running pvcreate (on the whole disk, and after creating an LVM partition /dev/sdb1) and it failed with error code 7. As another experiment, I tried setting up a loopback filesystem on a file in the root directory. That worked perfectly; vgscan picked it up, vgchange activated it, and the rest of the init script ran fsck and mounted it. Other than setting up the loopback file the only thing I did was add a call to losetup before the vgscan. Not sure if this is a problem with the kernel (i.e. SCSI driver) or a problem with LVM, or some boneheaded thing I'm doing wrong. Any advice you can give would be appreciated -- let me know if I can provide more information. thanks, jafager _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
