Hello and thanks for the answer.
For "political" (indeed) reasons, we can't use the raid 5......
and there is a partition using the whole second "disk" (ie raid array),
it is sdb 1. When I type the command pvcreate /dev/sdb or /dev/sdb1
i get the following message....device /dev/sdb1 not found or ignored by
filtering
xdub a écrit :
Hi,
No sure what you want to do with your 2 raid1 arrays... and
why you want to incorporate the first one into LV (?).
Did you partition your second array ? if not, you can create a PV
like this: pvcreate /dev/sdb. "pvcreate" can initialize a disk or
partition.
- pvcreate /dev/sdb
- vgcreate vg00 /dev/sdb
Again, no sure what you want to do, but with 4 HD you should consider
to build raid5 (hardware raid) and then create PV, VG, LV.

Hello Everybody
I have two raid 1 arrays on a Dell PowerEdge 2950,
1) 2*500 Go
2) 2*750 Go
I need to use LVM, to create a LV on the second raid array, in which
i will afterwards incorporate the first raid array. I have the latest
debian distro installed, with kernel updates, and LVM2 is installed.
I encounter my first problem when typing pvcreate /dev/sdb1. ( the
partition of the second raid array) I get the message :
device /dev/sdb1 not found or ignored by filtering
I checked /etc/lvm/lvm.conf, and I commented out the line about the
filter.
After a reboot, no more luck. I tried to circumvent the problem by
booting with an ubuntu CD, but i get the same error message.
Could anybody tip me about what's wrong and more importantly suggest
solutions to me ? :-)
Thanks a lot in advance.
