Determine resync direction from syslog?

Hi,

here's a somewhat funny situation:

A drive (/dev/sdb) of a RAID1 with damaged superblock is attached to a laptop. Someone stupid attaches another drive (/dev/sdc) with a very old backup mirror of /dev/sdb. And - the raid starts to sync:

Jan 21 20:46:32 localhost kernel: [ 7789.680603] md: bind<sdc1>
Jan 21 20:46:32 localhost kernel: [ 7789.681358] md: bind<sdc2>
Jan 21 20:46:32 localhost kernel: [ 7789.685163] RAID1 conf printout:

Which direction did the sync go?

Best regards,
