目前系统上没有挂载存储，但是在执行lvscan、vgscan及pvscan时，都有如下信息：

因为是利旧设备，不清楚之前是否挂载过存储，虽然知道目前这些提示信息对系统没什么影响，但还是想清除，请各位高手赐教，谢！！

    不是可以屏蔽这些提示字符吗？

资料：
By creating LVM on RAID 1 device, it could happen PVs are not created on the RAID device but on the physical partitions (e.g.: /dev/sda1 and /dev/sdb1 if there are part of /dev/md0). This will result as an error by doing LVM scanning (pvscan, vgscan, ...) like Found duplicate PV 9w3TIxKZ6lFRqWUmQm9tlV5nsdUkTi4i: using /dev/sda1 not /dev/sdb1 and will make impossible to create a new volume group on /dev/md0. In this case, you have to create a filter for LVM. In the /etc/lvm/lvm.conf file, you have to add such a line: filter = ["r|/dev/cdrom|","r|hd[ab]|" ] Logically, replace "hd" with "sd" for SCSI devices and "ab" with the correct one. This will prevent such devices are scanned or used for LVM. You have to reload LVM with /etc/init.d/lvm force-reload but since your system is on LVM, this is not possible. Therefore you have to reboot.

我在lvm.conf文件中添加了如下红色部分
# By default we accept every block device except udev names:
filter = [ "r|/dev/.*/by-path/.*|", "r|/dev/.*/by-id/.*|", "a/.*/","r|/dev/sde|" ]

reboot之后用lvscan之类的看不到之前的报错信息了，但是为什么我只是添加了对sde的过滤，可实际上系统把所有sde之后的都过滤了呢?
