Not really. The use case is so simple that I really don't think it is a general problem. Otherwise everyone would be complaining about it. I'll = see if I can schedule some more downtime for the server to run some more = tests of this. (I only did it once, and because the machine was live at the = moment the lockup of the ataraid arrays made it quite a mess, so I'm hesitant = to try it again unless I'm in single user mode.) This was the command I issued that resulted in the crash. Nothing = strange about it as far as I can tell (taken directly from the gstripe man = page). gstripe label -v -s 4096 data /dev/da15 /dev/da16 /dev/da15 and /dev/da16 had been labeled and newfs'ed, but were not = mounted at the time. As I said, if I get a chance I'll look at this next time the machine is = down in single user mode. I forgot to do that earlier this morning when I did = a lot of testing to try to get around the SATA vs. preemtion problem I'm seeing. /Daniel Eriksson
