Hello, It seems that diskdrake uses a pvcreate to add the pv in the vg. After I made a lvextend on the lv mounted as / of 500Mb and a rizerfsresize. This was working fine. The problem occured after reboot. I did not run lilo to recreate the Master boot sector and may be it is one problem as / in a lv. I tried the recue disk, but Mandrake did not include the lvmtools, so I tried a new installation. The installation process told me that there was illegal division by 0 when acessing the information of the vg. So i did not change anything an stopped the installation, (switch off the pc because there is no sofware abort possible without change of the disk data at this stage of the installation). As I had no solution on the portable, I took the disk out of my portable, and put it as primary (so the disk is hda as in the portable) in a fixed machine (special cables available), I added a second disk as slave and installed the distribution on the second disk. Then the MSB has been replaced. That is really a problem because now I can not even start booting on the portable disk. All the tools are now available, diskdrake told me that the partition I finally added was not in the vg. So I added the partition. It was an error I completly realize it now. An error has been repported on pvcreate, but mainly it has been done, but the data in /etc has not been created. whith pvdata now I can see that I have 2 pvs with number one. The orgiginal first and the volume i finally added. pvremove reports an error, and does nothing. vgscan does nothing on rootvg as it is inconsistant. Anyway the system do not know the vg, /dev/rootvg/[12] do not exist. I think I should first, by patching the data by hand, either remove the last pv I added, or make it as beeing the 3rd pv of the vg. What ever I have to patch, I have to make the data on the 3 pv consistant. After I may have to mknod few things to have the/dev/rootvg/[12] device available. I hope a vgscan will be able recretate the data /etc/lvmconf and that the data will then be available. I will then backup the data, put the disk back in the portable and reinstall everything. Is there any hope such a process would work, and what to patch, where can I find a description of the data structure ? I am preparing a mail whith pvdata results ...
