Re: [osol-discuss] zpool attach, prtvtoc, fmthard fmthard: Cannot open device /dev/rdsk/

Actually, I have a theory that I think might explain what is causing the 
problem. I don't think you can use pipes with pfexec because pfexec causes 
commands to run in their own privileged shell and that privileged shell won't 
go through a pipe (I'm not really a Solaris expert, I'm just guessing here).

I don't think you can be a normal user at a BASH prompt and do:

$ pfexec prtvtoc /dev/rdsk/c8t0d0s2 | fmthard -s - /dev/rdsk/c8t2d0s2

instead, I think you have to be a root user and do this:

# prtvtoc /dev/rdsk/c8t0d0s2 | fmthard -s - /dev/rdsk/c8t2d0s2

So type in this command:

  su - root

and enter in the root password to become the root user and then type in your 
command:

  prtvtoc /dev/rdsk/c8t0d0s2 | fmthard -s - /dev/rdsk/c8t2d0s2

If you look at the explanation at the link that I gave you in my previous post, 
you will see that all of the commands were done as the root user and were not 
executed through pfexec.

If you still think that "the drive is busy with something", you can check what 
processes are using the drive or file system by using the "fuser" command. Type 
this in at the command line:

    man fuser

for details. I also recommend reading the 

    man pfexec 

and

   man pfsh

man pages to check if it says anything about using pipes or not (to be honest, 
I don't really remember off the top of my head whether it does and I'm working 
on a Debian machine right now, so I didn't bother to check the Solaris man page 
before posting this).
