Hello, As per: http://lists.freebsd.org/pipermail/freebsd-stable/2007-July/036266.html The hw.mpt.enable_sata_wc sysctl will enable write caching on SATA drives with the mpt driver. My question is, will explicit requests to flush the cache, such as those made by ZFS, still propagate to the drives? -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
