Hi all I have installed FC10 on a new hdd. I have an existing FC10 on another hdd, and I want to copy some data onto the new hdd. I have put the old hdd into the same machine, as a secondary drive, but I am having difficulty in mounting it. Here is the output of fdisk - -------------------------------------------- [root@localhost ~]# fdisk -l Disk /dev/sda: 20.4 GB, 20495658496 bytes 255 heads, 63 sectors/track, 2491 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x972f8d73 Device Boot Start End Blocks Id System /dev/sda1 * 1 25 200781 83 Linux /dev/sda2 26 2491 19808145 8e Linux LVM Disk /dev/sdb: 20.0 GB, 20019314176 bytes 255 heads, 63 sectors/track, 2433 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xd56bd56b Device Boot Start End Blocks Id System /dev/sdb1 * 1 25 200781 83 Linux /dev/sdb2 26 2433 19342260 8e Linux LVM ============================================ If I try to mount /dev/sdb2, I get the message "unknown filesystem type 'lvm2pv'". I googled for this, and got quite a few hits, but I still can't get it right. Here is the output of pvscan - -------------------------------------------- [root@localhost ~]# pvscan PV /dev/sdb2 VG VolGroup00 lvm2 [18.44 GB / 32.00 MB free] PV /dev/sda2 VG VolGroup00 lvm2 [18.88 GB / 32.00 MB free] Total: 2 [37.31 GB] / in use: 2 [37.31 GB] / in no VG: 0 [0 ] ============================================ As you can see, /dev/sdb2 is part of VolGroup00, which according to /etc/fstab is mounted to /. I can see the contents of /dev/sda2, but not /dev/sdb2. I tried to create a new volume group for /dev/sdb2, as follows - -------------------------------------------- [root@localhost ~]# vgcreate hdd2 /dev/sdb2 Physical volume '/dev/sdb2' is already in volume group 'VolGroup00' Unable to add physical volume '/dev/sdb2' to volume group 'hdd2'. ============================================ So I tried to remove /dev/sdb2 from volume group 'VolGroup00' - -------------------------------------------- [root@localhost ~]# vgreduce VolGroup00 /dev/sdb2 Physical Volume "/dev/sdb2" not found in Volume Group "VolGroup00" ============================================ That seems strange. I tried to remove it using the gui tool Logical Volume Management. This gives the message 'Volume Group VolGroup00 does not have enough space to move the data stored on /dev/sdb2. A possible solution would be to add an additional Physical Volume to the Volume Group.' I don't know why it says that. All I want to do is remove a physical volume from a volume group. Now I have run out of ideas. Please can someone explain how I can mount my old FC10 drive in my new FC10 machine.
