Subject: [PATCH 1/2] Incremental: Remove redundant spare movement logic
|
|
Git-commit: 69068584f9ed68b8b2736287a1c9863e11b741d5
|

References: jsc#SLE-13700, bsc#1180220

|
|
If policy is set then mdmonitor is responsible for moving spares.
|
|
This logic is reduntant and potentialy dangerus, spare could be moved at
|
|
initrd stage depending on drives appearance order.
|
|
|
|
Remove it.
