I don't know if that patch is the key....
I also heard that the kernel level(2.2.19) I use has already supported dynamic major number...
Actually, I can format and mount those disk with major number 254 individually all right. Just couldn't pvcreate with them. Any other advise?

dynamic additional major in order to work around this constraint.
Not the future Linux 2.5 concept though, where minors won't be limited to 8 bit any longer. That's the way we want to support it BTW.

I traced lvm kernel source and found that in
