[linux-lvm] pvcreate fails on a software RAID metadisk

[Bill Ellis]

Hi again,

Some more playing around led me to discover that 'lvmdiskscan' is also not
recognizing my software RAID metadisks correctly.  Here's what I think are the
relevant portions of the ~5600 lines of output from the 'lvmdiskscan -d -v'
command:

Again, if anyone can give me any leads as to what might be going wrong here,
I'd appreciate it.  Also, if there is any more information I can provide on
this matter, just let me know...

Thanks,
Bill
