Description: Initially, no vg is active. At this point, the directory /dev/mapper looked like the following: # ll /dev/mapper total 0 crw------- 1 root root 10, 63 Nov 28 08:57 control Volume group vg1 is created. Logical volume is created with persistent minor number (lvcreate -M y --major 253 --minor 51 -n lvol1 -L 100M vg1). This logical volume device node should be created with minor number "51". But it is created with dynamic minor number. Expected Behavior: ll /dev/mapper should show "brw------- 1 root root 253, 51 22 Nov 28 15:06 vg1-lvol1 Actual Behavior: ll /dev/mapper should show "brw------- 1 root root 253, 0 22 Nov 28 15:06 vg1-lvol1 Please let me know if there is any solution or workaround for this problem. Thanks Asha </BODY> </HTML>
