> Er... excuse the question, what is "volatile write caches"?
write caches that lose your data when they lose power.
Consumer hard drives usually have 8-16-32MB write caches; if the drive loses
power, the cached data evaporates and never hits the disk - but the disk
already told xfs that the data was safe, and xfs has moved on. This violation
of trust between fs and disk can cause filesytem corruption :)
Options are to get a ups, or turn off write caches. Or to find out why you're
losing those IOs, and keep using barriers.
