When Im trying to access my stripeset I got:
FOOO: g_access failed: 1
it is 5.3-STABLE
I have not made any changes to the system sources, including Vinum
the output of the vinum list command

-I had a crash, but I had generic kernel that time and can not reproduce it
though some info from the screen :

GEOM_VINUM: subdisk vol.p0.s0 is down

Fatal trap 12: page fault while in kernel mode
fatal virtual address = 0xf8
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc5eee5ad
stack pointer = 0x10:0xe4e17cf4
frame pointer = 0x10:0xe4e17d00
code segment = base 0x0, limit 0xfffff, type 0x1b

processors eflags = interrupt enabled, resume, IOPL = 0
current process = 21704 (gv_v vol)
trap number = 12
panic: page default
Uptime: 1d8h45m17s
I see its a hardware error, but still any chance to recover some of
the 447Gb would be great
The problem is more complicated since I have used gbde to encrypt the
volume which has worked fine, though I first have to attach the drive
to run fsck or anything and the command
gbde attach /dev/gvinum/vol -l /tmp/key
It says: gbde: Attach to gvinum/vol failed: could not access consumer
Any help would be appreciated
