One hard drive offline although it is plugged in

[Ghwomb]

I have n00b-crashed my system. At least sort of. I have four drives connected and visible from the GUI, but the zpool as a whole is in a degrades state.

Code:

root@freenas ~]# zpool status -v                                                                                                 
  pool: Spegel

I think one of my hard drives is off-line, but I don't know how to bring it on-line again.

Use the manual. :)

I have tried the steps which I think is appropiate. But I get an error:

Code:

Error: Disk replacement failed: "invalid vdev specification, use '-f' to override the following errors:, /dev/gptid/3d8c893d-6d94-11e3-9621-d43d7ebc5ce0 is part of active pool 'Spegel', "

• Several reboots did not help.
• I could not do these steps because of permission errors, which seems to be by proper design.
• Quickwipe from GUI did not work at first, permission error.
• Wipe with zeros from GUI worked. So I ran that, it stuck at 100%. Since the hard drives was not spinning I aborted after about half an hour.
• Did quickwipe and it worked this time.
• Rebooted
• Now I could replace my drive as per step three.
• Detached my ghost drive, as per step four.
• The zpool status -v command reported that everything was OK, as did the GUI. But I could not get rid of the red light alert in the upper right corner until I rebooted.

To sum it all up, everything is back to normal.

FreeNAS and ZFS must be some of the most excellent code written ever. Since it can withstand and survive such an onslaught of an inept amateur sysadmin. And nowhere in sight was the Windows motto "Reformat and reinstall the system" uttered.
