I'm probably missing something very simple. My hard drive looks like this: [root at mavis ~]# fdisk -l Disk /dev/hdb: 163.9 GB, 163928604672 bytes 255 heads, 63 sectors/track, 19929 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 19929 159975270 8e Linux LVM Inside the Logical Volume there are my / partition and swap partition and CentOS4 sorts it out just fine. [root at mavis ~]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) <snip> /dev/hdb1 on /boot type ext3 (rw) However, if I boot e.g. KNOPPIX, I'm unable to mount anything except the /boot partition on hdb1. Is there any way out of this intolerable situation other than doing a full backup, repartitioning the hard drive without that damnable LVM and restoring the whole thing from the backup?
