Need to add an lvm from the command line

Thaidog · 10-29-2010, 06:47 PM

I have made lvms with gentoo but my technique seems not to be working. I have a disk /dev/sdb1 which I made after the system install on disk /dev/sda1. I am trying this:

vgscan

vgchnage -a y

pvcreate /dev/sdb1

lvm bitches out with:

[yo@with]# pvcreate /dev/sdb1
Device /dev/sdb1 not found (or ignored by filtering).

X is not installed and system-config-lvm is not working with the command line.

again, how many disks do you have? 'cause you said you have /dev/sda, but you tried

Code:

pvcreate /dev/sdb1

Sorry - should have been /dev/sdb1:

pvcreate /dev/sdb1

Yes I did. I ended up using a "new method" where you use this command:

kpartx -a /dev/mapper/mpath0

if your system-config-lvm is not working then do this command <yum install system-config-lvm*> . then it will working.
