This might be due to bad detection of cache vdevs by blkid. A patch to
blkid has been merged, but I don't know if it will ever make it to Ubuntu
I posted a dirty, bad, naughty, unsafe workaround at
The workaround involves dd'ing part of an ext2 image over the beginning of
your cache vdev, corresponding with an unused portion of the zfs label.
You may be better off forcing the patched blkid into your initramfs, but I
have 0 data loss with the ext2 bodge.
