[linux-lvm] pvcreate on a dmraid device

[linux-lvm] pvcreate on a dmraid device

[-- Attachment #1: Type: text/plain, Size: 1324 bytes --]

Hi,

I'm new to this list, but not to Linux and LVM.
I'm trying to setup a new Linux-server with an on board RAID-controller 
(Promise PDC20265 FastTrak100 Lite/Ultra100). Now everything goes well until 
I try to do a pvcreate on one of the raid-partitions, this is the output I 
get:
# pvcreate /dev/mapper/pdc_edcfibbf4
  Device /dev/mapper/pdc_edcfibbf4 not found.

But the device-file is there (along with the other partitions).

# ll /dev/mapper/pdc_edcfibbf*
brw-------  1 root root 253,  7 Nov  4 18:22 /dev/mapper/pdc_edcfibbf
brw-------  1 root root 253,  8 Nov  4 18:22 /dev/mapper/pdc_edcfibbf1
brw-------  1 root root 253,  9 Nov  4 18:22 /dev/mapper/pdc_edcfibbf2
brw-------  1 root root 253, 10 Nov  4 18:22 /dev/mapper/pdc_edcfibbf3
brw-------  1 root root 253, 11 Nov  4 18:22 /dev/mapper/pdc_edcfibbf4

and dmraid shows the raidgroup OK:
# dmraid -s
*** Active Set
name   : pdc_edcfibbf
size   : 160086465
stride : 128
type   : mirror
status : ok
subsets: 0
devs   : 2
spares : 0

Any suggestions on how I can solve this issue and move on with my 
installation.

Regards,

Look for (commented out) types line in lvm.conf
and enable it saying:
  types = [ "device-mapper", 1 ]

(This will happen by default in the next release.)

Dan,

change your lvm2 "devices" configuration in /etc/lvm/lvm.conf to include:

types = [ "device-mapper", 254 ]
