Hi, I have found what I think is a display bug from lvm pvs. Steps to recreate: 1) Create VG spanning 3 PVs 2) Loose 2 PVs 3) Use lvm pvs to display columns including lv ones Output includes one of the unknown devices duplicated rather than both of the unknown devices. # lvm pvs -o pv_name,pv_uuid,pv_size,lv_name Couldn't find device with uuid JWGqaR-B3A9-fJKt-KuHY-MiER-3e7d-isOzhv. Couldn't find device with uuid BCj73p-w7vN-T0s7-Or9G-vXYr-9zkW-3R3u6n. PV PV UUID PSize LV /dev/sda11 CcVFFD-yc6u-h06D-OLAW-xkBJ-0Hl7-RKgEn0 104.00m unknown device JWGqaR-B3A9-fJKt-KuHY-MiER-3e7d-isOzhv 204.00m unknown device JWGqaR-B3A9-fJKt-KuHY-MiER-3e7d-isOzhv 204.00m Also is there an official location for reporting LVM bugs? Red Hat's bugzilla perhaps? Full recreation steps below.
