Does anyone knows how to disable write cache of hard disk?
I have found some hints here at Freebsd website:
However, this seems only work for ATA devices, what about SAS/NLSAS devices
(Meanwhile, it seems that there is no such sysctl in latest Freebsd release,
which is 10.0)?
Any hints are welcomed!
Thanks in advance.
