Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-lvm@redhat.com I'm trying to extend a root LVM. I'm using LVM2 on FC2. Here is what I've tried: I ran lvextend when the system was booted normally and the volumes were mounted. This worked as expected and lvdisplay properly shows the new larger size. Then I booted into the FC2 rescue CD and instructed it to NOT search for and mount Fedora installations. I then ran: # resize2fs /dev/Volume00/LogVol00 I don't have the specific error, but it basically says that the specified volume doesn't exist. Indeed if I look in /dev, my volume group and volumes are nowhere to be found. At that point I tried: # lvm lvm> vgscan After only about 1 second, it responds that no volumes are found. I also tried rebooting from the CD and letting it mount my installations. In this case, the volume and volume groups are properly discovered and mounted. However, if I try to unmount the volume, it always responds with "device busy". Is this a problem with how the FC2 rescue disk scans for volumes? Any help would be appreciated.
