Since you have a rack-mounted system, chances are good you have more rack-mounted systems. Of course this is still all moot, because John insists that the RAID reduce function doesn't need to address reducing mounted file systems ... and your 1U system is booted to the very file system that needs to be reduced. So we have come full circle. A md reduce isn't practical unless it includes on-line file system support, which is a deal-killer as it not only requires massive development efforts outside of the LINUX RAID group, but has to be done in conjunction with the developers in this group. Just suck it up and mount all the disks somehow (or use backup). Either give up on resizing, or install Solaris with ZFS boot, then you can resize all you want.
