Subject: Ignore error when setting sync_min
X-Git-Tag: mdadm-3.2~78
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=18eaf9e553f5749b3ba527cf3bc069839a33486b;p=thirdparty%2Fmdadm.git

Ignore error when setting sync_min

When restarting an array that is in the middle of a reshape,
sync_min cannot be set.  So just ignore any errors we get
when trying to set it.
