Hi, all, Does anyone knows how to disable write cache of hard disk? I have found some hints here at Freebsd website: https://www.freebsd.org/doc/handbook/configtuning-disk.html 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. Peter
