What version of Solaris are you running? What does "got hosed" mean? There have been many improvements in proactively detecting failure, culminating in build 77 of Nevada. Earlier builds: - Were unable to distinguish device removal from devices misbehaving, depending on the driver and hardware. - Did not diagnose a series of I/O failures as disk failure. - Allowed several (painful) SCSI retries and continued to queue up I/O, even if the disk was fatally damaged. Most classes of hardware would behave reasonably well on device removal, but certain classes caused cascading failures in ZFS, all which should be resolved in build 77 or later. - Eric -- Eric Schrock, FishWorks http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
