Subject: [PATCH] Tell LVM DBus to refresh it's internal status during reset
|
|
|
|
Unfortunately some users run wipefs <disk> thinking it's enough
|
|
to remove all devices on top of the disk cleanly.
|
|
In cases where the PV is not directly on the disk, LVM DBus
|
|
doesn't get a udev event and doesn't remove the VG and LVs from
|
|
DBus so we think these still exist.
|
|
|
|
Resolves: RHEL-93967
