I've experienced several times that ZFS is very fault tolerant - a bit too tolerant for my taste - when it comes to faulting a disk. I saw external FC drives with hundreds or even thousands of errors, even entire hanging loops or drives with hardware trouble, and neither ZFS nor /var/adm/messages reported a problem. So I prefer examining the iostat output over `zpool status` - but with the unattractive side effect that it's not possible to reset the error count which iostat reports without a reboot, so this method is not suitable for monitoring purposes. -- Ralf Ramge Senior Solaris Administrator, SCNA, SCSA Tel. +49-721-91374-3963 [EMAIL PROTECTED] - http://web.de/ 1&1 Internet AG Brauerstraße 48 76135 Karlsruhe Amtsgericht Montabaur HRB 6484 Vorstand: Henning Ahlert, Ralph Dommermuth, Matthias Ehrlich, Andreas Gauger, Thomas Gottschlich, Matthias Greve, Robert Hoffmann, Norbert Lang, Achim Weiss Aufsichtsratsvorsitzender: Michael Scheeren _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
