Created attachment 1926603 [details] lvmdbusd flight recorder Description of problem: stderr from lvcreate is not included in the error we get from the LVM DBus job with the latest LVM 2.03.17. Version-Release number of selected component (if applicable): $ lvm version LVM version: 2.03.17(2) (2022-11-10) Library version: 1.02.187 (2022-11-10) Steps to Reproduce: Try to create an LV that is too big for the VG, The call fails as expected but, stderr is empty. # busctl call com.redhat.lvmdbus1 /com/redhat/lvmdbus1/Vg/0 com.redhat.lvmdbus1.Vg LvCreate "sta(ott)ia{sv}" test $((10*1024**3)) 0 0 0 (oo) "/" "/com/redhat/lvmdbus1/Job/0" # busctl get-property com.redhat.lvmdbus1 /com/redhat/lvmdbus1/Job/0 com.redhat.lvmdbus1.Job GetError (is) -1 "(\'com.redhat.lvmdbus1.Vg\', \'Exit code 5, stderr = \')" Expected results: With older LVM, the stderr is part of the error. # busctl get-property com.redhat.lvmdbus1 /com/redhat/lvmdbus1/Job/0 com.redhat.lvmdbus1.Job GetError (is) -1 "(\'com.redhat.lvmdbus1.Vg\', \'Exit code 5, stderr = Volume group \"testVG\" has insufficient free space (510 extents): 2560 required.\\n\')"
According to @vtrefny stderr is present when running lvm command separately. Issue is with dbus daemon.

Thank you, I can confirm the fix works (8f60c494515ddccb20e4afb804edb6b9599e65c0 is also needed), libblockdev test suite (thanks to which I originally discovered the issue) is now passing. Can we get this to Fedora rawhide soon?
