It should be possible to use the device unless there is some filter set. Run the command with debug on (add -vvvv) and you will see which filter disabled the device and why. I guess you can also hit this "known" problem with old lvm toolset (<2.02.29) and new kernel with new sysfs layout. *If* it is this situation you can fix it using one of the following 1) disable sysfs scan 2) upgrade lvm 3) switch CONFIG_SYSFS_DEPRECATED_V2 kernel config on and recompile kernel Milan -- mbroz@redhat.com _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
