Subject: [PATCH 14/61] Grow: block -n on external volumes.
|
||
|
|
Patch-mainline: mdadm-4.2+
|
||
|
|
References: jsc#PED-1009

|
|
Performing --raid-devices on external metadata volume should be blocked
|
||
|
|
as it causes unwanted behaviour.
|
||
|
|
|
||
|
|
Eg. Performing
|
||
|
|
mdadm -G /dev/md/volume -l10 -n4
|
||
|
|
on r0_d2 inside 4 disk container, returns
|
||
|
|
mdadm: Need 2 spares to avoid degraded array, only have 0.
