我无法添加新卷（由SAN存储设置）作为主机LVM卷的PhysicalVolume。 这是错误消息：
#sudo pvcreate /dev/sdc1 -v Device /dev/sdc1 not found (or ignored by filtering). 操作系统：Ubuntu 14.04.2 LTS（GNU / Linux 3.16.0-30-generic x86_64）
FDISK：
#sudo fdisk /dev/sdc -l Disk /dev/sdc: 2198.0 GB, 2197999845376 bytes 237 heads, 20 sectors/track, 905689 cylinders, total 4292968448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 1048576 bytes Disk identifier: 0x00031fdb Device Boot Start End Blocks Id System /dev/sdc1 2048 4292968447 2146483200 8e Linux LVM
分手：
#sudo parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: HP MSA 2040 SAN (scsi) Disk /dev/sdc: 2198GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 2198GB 2198GB primary lvm
filter（只有未注释的行）：
filter = [ "a/.*/" ] global_filter = [ "a|loop0|", "a|loop1|", "a|sda5|", "r|.*|" ]
partprobe：
sudo partprobe -s /dev/sda: msdos partitions 1 2 <5> /dev/sdb: msdos partitions 1 2 /dev/sdc: msdos partitions 1 /dev/sdd: msdos partitions 1 /dev/mapper/devstack--vg-swap_1: loop partitions 1 /dev/mapper/devstack--vg-root: loop partitions 1
我到目前为止所尝试的是：
问题是由Devstack安装生成的etc/lvm/lvm.conf中的global_filter设置。
我评论了这条线，现在可以正常使用pvcreate 。
#global_filter = [ "a|loop0|", "a|loop1|", "a|sda5|", "r|.*|" ] # from devstack
感谢@迈克尔汉普顿指出。
我在Debian 8上遇到类似的问题
> lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.7 (jessie) Release: 8.7 Codename: jessie > vgextend vg_data /dev/sdc Device /dev/sdc not found (or ignored by filtering). Unable to add physical volume '/dev/sdc' to volume group 'vg_data'.
与开放职位不同的是，我的global_filter被默认注释掉了，里面没有任何内容，所以我把它留下了。
# global_filter = []
此系统上有3个卷组，其中2个是使用安装创build的。 之后从sdd（与sdc相同的控制器）创buildvg_data，没有错误，整个磁盘都是RAW。
我终于走了以下步骤：
> parted /dev/sdc GNU Parted 3.2 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel gpt Warning: The existing disk label on /dev/sdc will be destroyed and all data on this disk will be lost. Do you want to continue?

我曾希望lvm会覆盖分区，并使用磁盘作为RAW，但…
> vgextend vg_data /dev/sdc Device /dev/sdc not found (or ignored by filtering). Unable to add physical volume '/dev/sdc' to volume group 'vg_data'.
所以最后我用分区和…
> vgextend vg_data /dev/sdc1 Physical volume "/dev/sdc1" successfully created Volume group "vg_data" successfully extended
yay vg_data终于被延长了
而不是注释整个行，可以添加你想添加的磁盘分区 – 在我的情况下，我也想添加/ dev / sdc1，所以把行改为：
global_filter = [ "a|loop0|", "a|loop1|", "a|sda5|", "a|sdb5|", "a|sdc1|", "r|.*|" ] # from devstack
之后，pvcreate命令正常工作。 不需要重新启动。
感谢原来的post和答案，但没有这些信息，我仍然试图弄清楚发生了什么事情。
