I tried this, but it would not mount the file system. I couldn't find
any errors, it just would silently drop the request. Not sure why. In
the process of this, I did backup all the files and rebuild the array,
without LVM. This time, I removed the journal from array. Maybe, because
there is no journal, nobarrier is ineffective and or causes it to not

I'm not convinced a new server or new drives would provide any different
experience, and I don't want to change the setup because it works for my
needs, but eventually I'll purchase larger drives, so maybe I'll play
with the nobarrier option then.

(My server is well backed up, and I have it on a battery, so I'm not
terribly concerned about the journal anyway. Besides, the volume is
encrypted, so if power went out and the server died, the last file being
written would be the least of my concerns.)
