[linux-lvm] Compaq Smart Array DL 350: logical units not recognized



Hi,

First of all, I would like to thank you for developping lvm, which seems to
me both simple and great.
We intend to use it for our production needs on a Compaq Smart Array
plateform (for hardware mirroring).

For our development platform, we created two logical units with the Compaq
utilities for Smart Array: /dev/ida/c0d0 for system and /dev/ida/c0d1for
data

Then we installed the Mandrake 8.0 with lvm-9._beta2 included.
/etc/modules.conf has been updated for lvm.

1) fdisk recognizes both the logical units

3) The problem is the following:

# lvmdiskscan
lvmdiskscan -- reading all disks / partitions (this may take a while...)

partition [0x82]
lvmdiskscan -- /dev/ida/c0d1p6  [     247.02 MB] Extended LINUX native
partition [0x83]

lvmdiskscan -- /dev/ida/c0d1p7  [        251 MB] Extended LINUX native
partition [0x83]
lvmdiskscan -- /dev/ida/c0d1p8  [          2 GB] Extended LINUX native
partition [0x83]
lvmdiskscan -- /dev/ida/c0d1p9  [     398.42 MB] Extended LINUX native
partition [0x83]
lvmdiskscan -- /dev/ida/c0d1p10 [     127.48 MB] Extended LINUX native
partition [0x83]
lvmdiskscan -- /dev/ida/c0d1p11 [       1.41 GB] Extended LINUX native
partition [0x83]
lvmdiskscan -- no valid disks / partitions found
lvmdiskscan -- please check your disk device special files!

As you can see, lvmdiskscan sees everthing in double, as if c0d1 was
pointing to c0d0.

But the system works fine out of lvm. I can mount /dev/ida/c0d1p8 on /test
and create a file
# mount /dev/ida/c0d1p8 /test
# touch /test/test
# ls /test
lost+found/  test
# umount /test

pvcreate reacts the same way
# pvcreate /dev/ida/c0d1p14
pvcreate -- extended partition "/dev/ida/c0d1p14" doesn't exist
     -> actually, /dev/ida/c0d0p14 does not exist but c0d1p14 does

# pvcreate /dev/ida/c0d1p5
pvcreate -- can't use Linux SWAP partition "/dev/ida/c0d1p5"
     -> /dev/ida/c0d0p5 is indeed a swap partition, see lvmdiskscan

# pvcreate /dev/ida/c0d1p6
pvcreate -- invalid partition type 0x83 for "/dev/ida/c0d1p6" (must be
0x8e)
     -> In fact, c0d1p6 is of 0x8e type (see fdisk) , but c0d0p6 is indeed
of 0x83 type

I've been seeking around the internet for solutions or similar bugs but I
just found one similar:

Any help ?

Thanks,

Vincent Guillet
