Hello List,

I am using lvm version 2.02.177(2), tried to create a mirrored LV, but failed with the errors,
tb0307-nd1:~ # pvs

Could you help to take a look at this problem? from lvcreate man page, the mirrored LV is supported by lvcreate.
my lvm2 version/configuration is as below,

Clustered old mirror needs 'cmirrord' to be installed and running.

Hi Zdenek,

Clustered old mirror needs 'cmirrord' to be installed and running.

--enable-cmirrord
Yes, the configuration error led my LVM2 mis-function.

Thanks a lot.
Gang
