Subject: [PATCH] daemon: lvm: Do reverse device name translation on pvs_full
|
||
|
|
device fields
|
||
|
|
|
||
|
|
Intermittent test failures in virt-filesystems showed that when using
|
||
|
|
the pvs_full API, the pv_name field in the returned list of structures
|
||
|
|
was not being reverse translated. As a result internal partition
|
||
|
|
names could appear in the output of virt-filesystems.
|
||
|
|
|
||
|
|
See: https://listman.redhat.com/archives/libguestfs/2023-July/032058.html
|
||
|
|
(cherry picked from commit 32cb5b45cfbe5edbc7643fc533da70db2d3c6cda)
