Mark, please would you enable the debug messages as described in the docs, viz. the following settings in lvm.conf: log { file="/tmp/lvm2.log" level=7 activation=1 } then look at /tmp/lvm2.log after running the problematic command? > device-mapper: couldn't split parameters > device-mapper: error adding target to table The log file will show you the actual parameters that were passed to device-mapper leading to the error messages. Please put the log file(s) somewhere on the web and post URL(s) to the list - or mail the log file(s) to me privately as a *compressed* attachment.
