Subject: [PATCH] mdadm: treat the Dell softraid array as local array
|
|
Patch-mainline: N/A, in-house usage only as a workaround to Dell's softraid bug
|
|
References: bsc#1175004
|
|
|
|
Dell softraid FW uses homehost in md raid superblock to store
|
|
its virtual disk name e.g. "VirtualDisk01". The improper usage
|
|
of md raid super block meta data from Dell softraid S150 utility
|
|
makes mdadm takes such md raid (Dell softraid Virtual Disk) as
|
|
foreign array and won't automatically assemble this array by
|
|
default. Here if an array's homehost name starts with "VirtualDisk"
|
|
then we take it as a Dell software raid and bypass the set_name
|
|
checking. This workaround makes current Dell software raid array
|
|
can be treated as local array and start automatically.
|
|
|
|
This workaround patch will be withdrawn after Dell softraid FW
|
|
fixes the improper usage problem on md raid superblock.
