在某RHEL 5.6系统中查询PV时有个输出如下，有点困惑。
我这边的多路径软件使用的是multipath, 设备名里面都带了msa193079字符串，因此修改/etc/lvm/lvm.conf如下 :
# pvscan

注释这行, # filter = [ "a/.*/" ]
然后新增这行:
filter = [ "a/msa193079.*/" "r/.*/" ]
表示允许accept带
msa193079字符串的设备, 拒绝reject所有其他设备.
删除缓存/etc/lmv/cache/.cache
重新扫描,
之后的
重新执行pvs就不在报
了。
pvscan
vgscan
lvscan之后的
cat /etc/lvm/cache/.cache # This file is automatically maintained by lvm.
