Mattias pointed out to me in a private email I missed Carsten's mention of hdparm --make-bad-sector. Duh! So Carsten: Mattias is right, you did not simulate a silent data corruption error. hdparm --make-bad-sector just introduces a regular media error that *any* RAID level can detect and fix. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
