<div dir="ltr">I'm trying to copy data from an old laptop drive to a new one. I spent a lot of time trying to mount /dev/sdb3, which I thought was the data part of the old hard drive. After a period of time, I found it to be a logical partition, not an ext3 partition. /sbin/fdisk /dev/sdb Command (m for help): p Disk /dev/sdb: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x9aa39aa3 Device Boot Start End Blocks Id System /dev/sdb1 * 1 2076 16675438+ 7 HPFS/NTFS /dev/sdb2 2077 2101 200812+ 83 Linux /dev/sdb3 2102 9729 61271910 8e Linux LVM I did a bunch of digging and learning and I found this: # /usr/sbin/lvdisplay /dev/sdb3 File descriptor 5 left open File descriptor 7 left open WARNING: Duplicate VG name VolGroup00: Existing YqG9FW-dYws-fSyZ-9lHS-ABjH-NuA5-GimBgI (created here) takes precedence over M7hbJ2-PNaC-5B8V-7VL8-vsWy-XuD0-LvkXVK Volume group "sdb3" not found From this I conclude that my computer has 2 LVs of VolGroup00 and in fact, it does. sda2 and sdb3. I was perfectly competent at mounting and working with regular partitions. But these LVMs are a different matter. How does one rename the partition so that there aren't 2 the same and then mount it ? There is no LV option in mount. How does one fix the fact that there are 2 VGs with the same name ? I don't need to use LVs. Is there a way to convert a working system to use regular partitions ? I tried gparted, but it doesn't work with LVs. Thanks. </div>
