I have some questions from a customer about zfs checksums. Could anyone answer some of these? Thanks.
Brian Customer: I would like to know more about zfs's checksum feature. I'm guessing it is something that is applied to the data and not the disks (as in raid-5). For performance reasons, I turned off checksum on our zfs filesystem (along with atime updates). Because of a concern for possible data corruption (silent data corruption), I'm interested in turning checksum back on. When I do so, will it create checksums for existing files or will they need to be rewritten? And can you tell me the overhead involved with having checksum active (CPU time, additional space)? -- Brian McBride System Support Engineer Sun Microsystems Cell: 206-851-1028 Email: [EMAIL PROTECTED] _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
