Yep. Just do a 'zpool replace zmir <target> <spare>'. This is what the FMA agent does in response to failed drive faults. > - In this instance the spare is twice as big as the other > drives -- does that make a difference? Nope. The 'size' of a replacing vdev is the minimum size of its two children, so it won't affect anything. > - Is there something inherent to an old SCSI bus that causes spun- > down drives to hang the system in some way, even if it's just hanging > the zpool/zfs system calls? Would a thumper be more resilient to this? There are a number of drive failure modes that result in arbitrarily misbehaving drives, as opposed to drives which fail to open entirely. We are working on a more complete FMA diagnosis engine which will be able to diagnose this type of failure and proactively fault the device. I'm not sure exactly what behavior you're seeing by 'spun-down drives', so this may or may not address your issue. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
