Can't import a pool .... missing device.

[math316]

Hi !

I'm new with Freenas and Linux so be patient with me lol

I've installed freenas on an old Dell 8400. Everything was working fine. I've created a zfs volume to share all my video and music with my other pc and DLNA devices. In this pool, there was only one 2To disk. I wanted to extend it so I did. I added a 1To disk , a 160Go disk and a 80go disk. Everything was added without mirroring or other type of raid. Just a pool of 2To+1To+160Go+80GO. The last I ad was a mistake so I detach the volume (I know don't say it, my mistake .... ).
Now, I want to import it but I can't. When I try to import, command promt says that a device is missing (the 80Go disk) but it is still connected to the computer. I've tried everything I saw on this forum and on the Solaris website (Command promt, gui, ....). I even try to connect the 80Go disk on an other sata connector but still invisible .... The disk is working fine so I really don't understand.....

All my music and video are still on the 2To disk (I guess ...) so if it's not possible to recover the pool, is it possible to recover the data with a program like Testdisk ?

Thanks !!!

Which commands did you use to detach? Could you share the results of "zpool history" from the command line?

I detach the volume in GUI. How can I share the result ? I only saw the latest changes (since reboot) .....

 

[math316]

Another thing : I can see the "missing" disk in gui ....

 

[bollar]

Code:

zpool history

should show us what the GUI did. My guess is that the drive was made offline and now needs to be made online again with a command like

Code:

zpool online (name of the missing drive -- the long number you see in Volume Status)

I did Zpool history but the only results I can't go up enough to see what happen .....

I did Zpool history but can't go up enough to see what happen ....

I did Zpool online but answer is Cannot open 'Media' : no such pool ....

For the last one, I can't go up enough to see everything .... is it possible to go up in command promt ??

[SCROLL LOCK], then the arrow keys if you are on the console.

I take it da1 is an unrelated pool and ada0 is the problem disk?

Code:

gpart show ada0

smartctl -q noserial -a /dev/ada0
