I'm trying to extend a root LVM volume (ext3) using the FC2 rescue CD. When I try to run resize2fs, it cannot see the volumes. vgscan also does not find anything. What am I missing?
What's the command? Any error messages?
Otherwise everything seems normal and I was able to run lvextend with no problem.
If you can use lvextend, then vgscan/vgchange has to have been run successfully, no?
Let me clarify. I ran lvextend when the system was booted normally and the volumes were mounted. This worked as expected.
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 dscovered and mounted. However, if I try to unmount the volume, it always responds with "device busy".
