Want to create LV Group but when i unmount /dev/sda5 this showing
[root@xen01 ~]# umount /dev/sda5 umount: /: device is busy umount: /: device is busy
This means disk /dev/sda5 is busy and due to this i can't create phsical,logical volume on this disk.
[root@xen01 ~]# pvcreate /dev/sda5 Can't open /dev/sda5 exclusively. Mounted filesystem?
please anyone can tell me how i do this task it's urgent..?
