Thanks for clarifying that point.
In meantime I rebooted server (shutdown was a struggle) - finally I fsck'd the filesystem (ext4) sitting on the raid6 - and manually ran the triggering rsync. This of course completed normally. That's either good or bad depending on your perspective :)
If I can get it to crash again, I will either start a git bisect (from 6.6.3) or see if 6.7rc4 shows same issue.
thanks,
gene
