The problem I am at, is that I changed motherboard, CPU, and 2 x GPU, and the new system does not recognize the file system (grub2 on master record, raid1, md0). All other stuff is md1, LVM, vg1 seven partitions: home, user etc.

With Knoppix 7.2.0, this morning I could fully analyze this amd64 raid1, with a recent kernel. It worked nicely, although by the vendor I had no internet connection.

7.2.0 did not work, as I said, with a lenny server (kernel 2.6), while it worked with i386, recent kernel.

Knoppix 5.3.1 failed to work with the new CPU-GPU machine, while it worked with the old server.

So, it seems that one should use the Knoppix version according to the Debian kernel age of his hardware.

All that just to answer quickly your kind message. Now I am busy in getting the new machine to work (molecular dynamics). After that, should you want detailed tests from me, please ask and I'll try to do (I am a biochemist, not and expert in computers, however)

Thanks
