Thanks for the update Adam, that's good to hear. Do you have a bug ID number for this, or happen to know which build it's fixed in? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensol

So, from what I gather, even though the documentation appears to state otherwise, default checksums have been changed to SHA256. Making that assumption, I have two questions. First, is the default updated from fletcher2 to SHA256 automatically for a pool that was created with an older version of
