Hello I am new to the truenas system. I created a pool of 3 striped disks and put my data in it. I then added 2 disks to my system and my initial file was then disconnected. how to put it back online. thank you for your help.
A stripe is a very dangerous setting.
hello, I’m starting my request again, having never posted on a forum. I have an old PC with truenas scale 24.10.0.2. I installed this on the PC and connected 3 1TB disks for files of no major importance in a strip pool. everything worked fine. When I wanted to add 2 more 2TB disks during reboot, the initial pool went offline. I haven’t found a way to connect them without destroying the previous data. My question is simple, is it possible to recover this bad manipulation? Thank you for your response.
Can you post the output of the following command:
sudo lsblk -o NAME,MODEL,SERIAL,LABEL,UUID,PARTUUID,TYPE
sudo zpool import
Please post the output of the following commands:
sudo wipefs --no-act /dev/sda1sudo wipefs --no-act /dev/sdb1sudo wipefs --no-act /dev/sdc1
this is the pool of the last 2 empty 2 tera disks
the 1st multimedia pool does not appear
This should fix the three-disk pool:
sudo wipefs --all --backup -t ntfs /dev/sda1sudo wipefs --all --backup -t ntfs /dev/sdb1sudo wipefs --all --backup -t vfat /dev/sdc1
Reboot after these commands that and the pool should appear.

Magnificent ! THANKS ! THANKS ! THANKS ! THANKS !
Can I now reassemble the 2nd pool even if it is not the same type?
Or should I attach it to the 1st pool?
What do you mean here?
You cannot merge pools. You can add further vdevs to an existing pool, but that will wipe the added drives.
What I want to do is add another pool with the last 2 disks mirrored on the “data” pool already created: the disks are empty. Is there no more risk?
Then you want to add another vdev to an existing pool, and that’s perfectly fine.
