Greetings, I've hit this exact 'bug': https://bugzilla.redhat.com/show_bug.cgi?id=491311 I need to remove the mappings manually. I assume this is done via 'multipath -F' followed by a 'multipath -v2' ? Has anyone experienced doing this on a production system?

I was thinking of taking out the

Hi, I connected my harddisk which had ext3 filesystem and some files archived in it as slave device and issued "mkfs /dev/hdb2" accidentally. Immediately I issued Ctrl C and stopped the process.
