When lvmetad is used and at the same time we're getting list of all PV-capable devices, we can't use cmd->filter (which is used to filter out lvmetad responses - so we're sure that the devices are PVs already). To get the list of PV-capable devices, we're bypassing lvmetad (since lvmetad only caches PVs, not all the other devices which are not PVs). For this reason, we have to use the "full_filter" filter chain (just like we do when we're running without lvmetad). Example scenario: - sdo and sdp components of MD device md0 - sdq, sdr and sds components of mpatha multipath device - mpatha multipath device partitioned - vda device partitioned => sdo,sdp,sdr,sds, mpatha and vda should be filtered! $ lsblk -o NAME,TYPE NAME TYPE sdn disk sdo disk `-md0 raid0 sdp disk `-md0 raid0 sdq disk `-mpatha mpath `-mpatha1 part sdr disk `-mpatha mpath `-mpatha1 part sds disk `-mpatha mpath `-mpatha1 part vda disk |-vda1 part `-vda2 part |-fedora-swap lvm `-fedora-root lvm Before this patch: ================== use_lvmetad=0 (correct behaviour!) $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0 use_lvmetad=1 (incorrect behaviour - sdo,sdp,sdq,sdr,sds and mpatha not filtered!) $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/sdo --- 0 0 /dev/sdp --- 0 0 /dev/sdq --- 0 0 /dev/sdr --- 0 0 /dev/sds --- 0 0 /dev/vda --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0 With this patch applied: ======================== use_lvmetad=1 $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0 |
