[PATCH] MD: not clear ->safemode for external metadata array

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shaohua Li <shli@xxxxxx>

->safemode should be triggered by mdadm for external metadaa array, otherwise
array's state confuses mdadm.

Fixes: 33182d15c6bf(md: always clear ->safemode when md_check_recovery gets the mddev lock.)
