Boot Volume still Degraded after replacing and resilvering (I think)

[aptoumanoff]

I did try to search and found many boot mirror issues, but none that helped me (in hindsight. If I'd followed instructions when the volume was initially degraded, I'd be fine).

A few days ago my boot mirror became degraded. I ordered replacement USB drives and backed up my config. When my new drives arrived I simply pulled the bad boot drive, put a new one in, and booted up. I then attached the new drive to the mirror and am now in this situation. I realize I should have replaced, not attached, and I realize that if I need to I can simply do a clean install and use my config, but I'd like to simply fix the issue if possible instead of starting over.

As you can see below I have two online boot devices and an unavailable device. The unavailable device is no longer physically attached to the machine. How can I remove it from the mirror? When I do this will my system stop saying the volume is degraded? What more information would you like to help me solve this? Thank you.

Code:

[root@freenas ~]# zpool status freenas-boot                                    
  pool: freenas-boot

status: One or more devices could not be opened.  Sufficient replicas exist for
        the pool to continue functioning in a degraded state.                  
action: Attach the missing device and online it using 'zpool online'.

The easiest thing for you to do is reinstall FreeNAS 9.10 and then restore your configuration file. As far as I can tell, you can't fix it via the GUI.

Try
# zpool detach freenas-boot 12264598356024334089

Which way did you do it? Did it succeed?

 

[SweetAndLow]

Just reinstall, its way faster.

The OP only posted the one time, 3 weeks ago. Maybe they solved it but never posted it.
