At some point multipath was setup on the local disk. dm-multipath has called it mpathb. when I do a vgdisplay of vg00 the pvname is /dev/mapper/mpathbp2 which is effectivly a link to /dev/sda2. I have run dmsetup and cannot remove the mpathb, mpathbp1, and mpathb2 entries since they are in use. I have been trying to figure out how to resolve this. I added filters to lvm.conf to not use anything with mpathb in the device file name. Upon reboot, I could only see lvol2 and lvol3 for vg00. I have more lvols than that. I have been tryinh to see if there is some data or cache file that dmsetup writes to. I have not seem anything. Any one have any good ideas?</P> Tue, 11 Sep 2012 16:23:15 GMT https://community.hpe.com/t5/operating-system-linux/cannot-remove-local-disk-from-multipath/m-p/5800707#M53895 feeble 2012-09-11T16:23:15Z https://community.hpe.com/t5/operating-system-linux/cannot-remove-local-disk-from-multipath/m-p/5800949#M53896 <P>Figured it out.
