Hi all,

One of my user have a big problem with gvinum and RAID5:

He builts a RAID 5 volume that worked great for two days.
But, when he reboot the PC it takes about 2 hours to get the disks to the
"UP" state:

Here is an example of output during the starting of the volume:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
3 drives:

D disk_ad1              State: up     /dev/ad1s1     A: 0/238475 MB (0%)

D disk_ad2              State: up     /dev/ad2s1     A: 0/238475 MB (0%)

D disk_ad3              State: up     /dev/ad3s1     A: 0/238475 MB (0%)

1 volume:

V fatty                 State: down   Plexes:       1 Size:        465 GB

1 plex:

P fatty.p0           R5 State: down   Subdisks:     3 Size:        465 GB

3 subdisks:

S fatty.p0.s2           State: I 70%  D: disk_ad3     Size:        232 GB

S fatty.p0.s1           State: I 70%  D: disk_ad2     Size:        232 GB

S fatty.p0.s0           State: up     D: disk_ad1     Size:        232 GB

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D

But, Once it gets to "UP", it's impossible to mount the volume:

mount: /dev/gvinum/fatty on /mnt/home1: incorrect super block.

then, I try an fsck:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
fsck -t ufs /dev/gvinum/fatty

Cannot find file system superblock

** /dev/gvinum/fatty

/dev/gvinum/fatty: CANNOT FIGURE OUT FILE SYSTEM PARTITION
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

How could he retrieves all the data stored on the RAID volume ?

Thanks,

Olivier
