Hello List, By default, devices/dir configuration option in /etc/lvm/lvm.conf is "=/dev". But, if I edit this configuration option, e.g. dir = "/dev/lvm", then lvcreate command will fail. sles12sp4-node:/dev # lvcreate -L2G -ay -n testlv vgdata /dev/lvm/vgdata/testlv: not found: device not cleared Aborting. Failed to wipe start of new LV. I am using lvm 2.02.183(or 180), this option can be edit individually? or any other option will affect this option, then lead to lvcreate failure. Thanks Gang _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
