You have been subscribed to a public bug:

I installed two new 6TB disks (WD Red) as RAID1 and pmove'd stuff over from old
5x3TB RAID10 array to it (actually the move is still in progress, going to take some
17 hours or so) and I get lots of these (4971 so far) in dmesg:

[58693.807553] bio too big device dm-7 (664 > 8)
[58694.037060] bio too big device dm-7 (1024 > 8)

Looks like an old kernel bug that was supposedly fixed in 2012:
https://lkml.org/lkml/2012/10/15/398

The LV that apparently triggered that is 3TB in size (90% full) and
encrypted with cryptsetup.

I don't know if this is reproducible but I can try - it'd just take some
two days every time (starting with restoring 3TB from backup).

Ubuntu 14.04.1, 3.13.0-37-generic x86_64 kernel,
Intel DQ57TM mobo, LSI 9211-8i SAS/SATA controller.
