vinum problems

[Marco Righele <marco_righele@xxxxxxxx>]

Greetings,

I'm testing vinum with the latest Stable kernel.
I tried to create a degraded raid-5 plex (a 3-disk plex, where only two 
  are really present) , but as soon as I run "vinum create -f 
configfile", the system crashes with the following message:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x33
fault code              = supervisor write, page not present
instruction pointer     = 0x8:0xd7357a28
stack pointer           = 0x10:0xd73468c0
frame pointer           = 0x10:0xd73468d4
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 838 (vinum)
current thread          = pri 6
interrupt mask          = none
kernel: type 12 trap, code=2
Stopped ad      open_drive+0x1f8:       movl    $0x10000,0x34(%eax)

I think vinum doesn't handle well the missing disk.
With the same configuration I can get the array up and running in 
FreeBSD 5.x (at least until I try to have vinum start at boot time...)

I can provide more information (and plenty of core dumps :D) if needed.

thanks,
Marco
