While trying to convert some Linux servers (Ubuntu 12.04) using VMware Converter I ran into an issue. Because of the servers being LVM based I could only see the /boot volumes and no other volumes, certain servers didn’t even show the /boot volume.
The problem is due to the newest LVM version which has some changes made into it. The amount of lv_attr has changed from 6 to 8, you can see this using the command “lvs” which will result into the following:
bash $ lvm lvs LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert root vg_lvm01 -wi-ao-- 495.55g swap vg_lvm01 -wi-ao-- 1.94g
The solution is to downgrade LVM with the version which came with the initial Ubuntu 12.04 release which can be found at http://packages.ubuntu.com/precise/lvm2/.
After the downgrade you will have only 6 parameters:
bash $ lvm lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert root vg_lvm01 -wi-ao 495.55g swap vg_lvm01 -wi-ao 1.94g
Run the converter again and all volumes will be visible again.
