A user specifying duplicate paths on the cmdline of vgcreate will get a message similar to the following: vgcreate vgtest2 /dev/loop3 /dev/loop5 Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop5 not /dev/loop3 Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop3 not /dev/loop5 Internal error: Duplicate PV id jk1lXs-Kzwy-OKlX-q6bh-aFFK-MQQ0-6oPgu8 detected for /dev/loop3 in vgtest2. This is caught by vg_validate(), but it would be good to find this condition earlier in the vgcreate code. add_pv_to_vg() currently checks by pvname, but does not look for duplcate pvids. This patch adds the check for duplicate pvids and results in new error output as follows: vgcreate vgtest2 /dev/loop3 /dev/loop5 Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop5 not /dev/loop3 Found duplicate PV jk1lXsKzwyOKlXq6bhaFFKMQQ06oPgu8: using /dev/loop3 not /dev/loop5 Physical volume '/dev/loop5 (jk1lXs-Kzwy-OKlX-q6bh-aFFK-MQQ0-6oPgu8)' listed more than once. Unable to add physical volume '/dev/loop5' to volume group 'vgtest2'. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>
