One question for Matt: when ditto blocks are used with raidz1, how well does this handle the case where you encounter one or more single-sector read errors on other drive(s) while reconstructing a failed drive?for a concrete example A0 B0 C0 D0 P0 A1 B1 C1 D1 P1 (A0==A1, B0==B1, ...; A^B^C^D==P) Does the current implementation of raidz + ditto blocks cope with the case where all of "A", C0, and D1 are unavailable? - Bill
I'll answer for Matt. Yes, 'A' will be reconstructed from B[0 or 1], C1, D0, and P[0 or 1]. -Mark _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
