I had a cheap-o USB enclosure that definitely did ignore such commands. On every txg commit I'd get a warning in dmesg (this was on FreeBSD) about the device not implementing the relevant SCSI command. This of course would affect filesystems other than ZFS aswell. What is worse, I was unable to completely disable write caching either because that, too, did not actually propagate to the underlying device when attempted. (I could not say for certain whether this was fundamental to the device or in combination with a FreeBSD issue.) -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schul...@infidyne.com>' Key retrieval: Send an E-Mail to getpgp...@scode.org E-Mail: peter.schul...@infidyne.com Web: http://www.scode.org
