tune2fs -o journal_data_ordered

Thanks! But, I'm curious: If I specify journal_data_ordered in tune2fs(8), and I put data=writeback in /etc/fstab, which mode actually gets used?

Set or clear the indicated default mount options in the filesystem.
I take this to mean that if you have "defaults" in /etc/fstab, then the FS option can specify what is the default for that particular file system. I would think the default would get overridden by an explicit mount option from /etc/fstab though.
But, that's easy to check. Just set the options on the FS level and/or fstab, mount and check dmesg to see what really happened.

Set or clear the indicated default mount options in the filesys-
tem. Default mount options can be overridden by mount options
specified either in /etc/fstab(5) or on the command line argu-
ments to mount(8). Older kernels may not support this feature;"
There are really three "defaults" of course. The filesystem implementation
level, the filesystem image level, and the /etc/fstab level, in that order.
