I have a Professional XXL with 2x 1TB HDDs (1TB RAID) server from velia.net and i want to create a volume group in it but when first i create pv it's showing.
[root@xen17 ~]# pvcreate /dev/sda3 /dev/sda3: open failed: No such device or address Can't open /dev/sda3 exclusively. Mounted filesystem?
And the output of.
[root@xen17 ~]# grep filter /etc/lvm/lvm.conf | grep -v "#" filter = [ "a/.*/" ]
sometimes it shows
[root@xen17 ~]# pvcreate /dev/sda3 Device /dev/hda1 not found (or ignored by filtering).
Now i am confused why this disk is behaving like that please help me in this i am struggling in this since 4 days. Any help will be appreciated.
