I had set up a Red Hat 9.0 Box with no xwindows on it just mainly the basic install. The /boot, / , and swap are all on HDA....then on HDG and HDH I set up a LVM during the install. After I filled the drives in the LVM with data I tried to add to more drives to it they were HDC and HDD. I'm not the best at this, so I was reading how on the interent...I first tried to just do vgextend and it would error, so i done a pvcreate for each drive and then done a vgextend then I rebooted, I never did a change. so now when it boots it errors out trying to mount the volume and I would have to go into maintenance and edit the fstab and comment out the volume so it will boot This is what I get when I do a pvscan: pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/hdg1" is associated to unknown VG "Volume00" (run vgscan) pvscan -- inactive PV "/dev/hdh1" is associated to unknown VG "Volume00" (run vgscan) pvscan -- total: 2 [38.03 GB] / in use: 2 [38.03 GB] / in no VG: 0 [0] And this is what I get from a vgscan: pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/hdg1" is associated to unknown VG "Volume00" (run vgscan) pvscan -- inactive PV "/dev/hdh1" is associated to unknown VG "Volume00" (run vgscan) pvscan -- total: 2 [38.03 GB] / in use: 2 [38.03 GB] / in no VG: 0 [0] I can send you a vgscan -d if you like but it is quite long, I have data on the volume and would like to fix it, is there a way to fallback to how it was before I tried to add the other 2 hard drives? And if so how do I add the new ones properly? Thank You Dio There are 3 types of people in the world Those who can count and thos who can't
