不能在Centos上执行“lvcreate”：“not found：device not cleared”

我创build了volume group ，但是当我尝试创buildvolume group时，它失败了：

 [root@c7v232 ~]# vgdisplay --- Volume group --- VG Name vg_1afe5376c50bb27bdc8a0342a0bfb50b System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 13 VG Access read/write VG Status resizable MAX LV 0 Cur LV 0 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 89.87 GiB PE Size 4.00 MiB Total PE 23007 Alloc PE / Size 0 / 0 Free PE / Size 23007 / 89.87 GiB VG UUID JZMo2m-CgAd-iQ3l-sNcp-J0W5-jwfi-058onD [root@c7v232 ~]# vgs VG #PV #LV #SN Attr VSize VFree vg_1afe5376c50bb27bdc8a0342a0bfb50b 1 0 0 wz--n- 89.87g 89.87g [root@c7v232 ~]# lvs [root@c7v232 ~]# lvcreate -L 5G -n lv_pao vg_1afe5376c50bb27bdc8a0342a0bfb50b /dev/vg_1afe5376c50bb27bdc8a0342a0bfb50b/lv_pao: not found: device not cleared Aborting.

我知道有一个类似的问题，但它是debian，我无法在Centos中findudev 。
