In general, ZFS doesn't manage device timeouts. The lower layer drivers do. The timeout management depends on which OS, OS version, and HBA you use. A fairly extreme example may be Solaris using parallel SCSI and the sd driver, which uses a default timeout of 60 seconds and 5 retries. In the more recent Solaris NV builds, FMA has been enhanced with an io-retire module which can make better decisions on whether the device is behaving well. -- richard > Thanks, > -Luke > > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
