Hello, my understanding is that ZFS is specifically designed to work with write caching, by instructing drives to flush their caches when a write barrier is needed. And in fact, even turns write caching on explicitly on managed devices.
My question is of a practical nature: will this *actually* be safe on the average consumer grade SATA drive? I have seen offhand references to PATA drives generally not being trustworthy when it comes to this (SCSI therefore being recommended), but I have not been able to find information on the status of typical SATA drives. While I do intend to perform actual powerloss tests, it would be interesting to hear from anybody whether it is generally expected to be safe. -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller <[EMAIL PROTECTED]>' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
