Did you check the syslog for more info, like the message said?

I assume you are not running e2fsck on another node?  Perhaps you had started e2fsck previously and killed it?  If you are sure e2fsck is not being run, you can use:

tune2fs -f -E clear-mmp /dev/sdd1

to clear this flag, and then run "e2fsck -fy /dev/sdd1" again.
