I grabbed lvm2 src (git://sourceware.org/git/lvm2.git) and build from tag v2_02_168. It seems the basic "./configure" doesn't include a lot of components such as lvmetad. What are the config options you would recommend to use? Thanks. -Shawn On Tue, Mar 14, 2017 at 7:04 AM, David Teigland wrote: > On Mon, Mar 13, 2017 at 06:12:06PM -0700, Neutron Sharc wrote: >> error 1: >> Physical volume '/dev/mapper/360000000557b690283509c3709c4fc0b' is >> already in volume group 'vol8', >> Unable to add physical volume >> '/dev/mapper/360000000557b690283509c3709c4fc0b' to volume group >> 'vol14'. >> >> error 2: >> Found duplicate PV W9rMQ0GuoNw9rnzK8x47OVEY044A2mgT: using >> /dev/mapper/360000000a1d91e849f66dd53a61d8fa9 >> not /dev/mapper/360000000e2ddd2a9380e9159902d9f73, Using duplicate >> PV /dev/mapper/360000000a1d91e849f66dd53a61d8fa9 without holders, >> replacing /dev/mapper/360000000e2ddd2a9380e9159902d9f73, >> >> error 3: >> Can't open /dev/mapper/360000000e2ddd2a9380e9159902d9f73 exclusively. >> Mounted filesystem? >> Unable to add physical volume >> '/dev/mapper/360000000e2ddd2a9380e9159902d9f73' to volume group >> 'vol2'. > > Fairly common problem, lvm needs to see only the multipath device and not > the components.
