Description Marian Csontos 2023-01-24 15:04:32 UTC
+++ This bug was initially created as a clone of Bug #2145114 +++

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?
