Subject: [PATCH 4/4] Add device symlinks to the PVs dictionary for MD RAID PVs
|
|
(#1389130)
|
|
|
|
Otherwise if the symlink is used to search for the PV info, it's not found and
|
|
everything on that PV is ignored which leads e.g. to issues when removing the PV
|
|
(as described in the bug) and others.
