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.

Try grep sda3 /proc/partitions to see if sda3 is actually available on your system.

If it is, then try grep sda3 /proc/mounts and see if the disk you are trying to use is not actually already mounted.

Note that in a XEN guest, your block devices are most likely not named sda (cat /proc/partitions to see what your block devices are).
