Need some help from anyone that knows their way out of this:
I set up TrueNAS Core on my old desktop. I used two old 500GB hard drives just to try out the system. Everyhing worked great. However, I knew the old drives wouldnt last long so I purchased two brand new WD 4TB Red drives. However, when I replaced the old drives, I wanted to clean up my TrueNAS interface so I deleted the old pools (I did not check wipe data option). Here’s the issue: There’s some files that were corrupted when I copied them from the old drives to an external drive. The original files on the old drives are not corrupted and I need to get them. I tried to mount the old drives on Ubuntu, but they flat out wont mount. Anyone know if can get the files on the old drives? Can I import the old drives ino the NAS? I’m at a loss here if anyone can help.
If you exported the pool and didn’t check the box to erase your data, you can import it again. Connect the drives to your NAS and import the pool through the GUI.
That’s the problem. I didn’t export the pools. However I did not check box to erase data.
What did you do, then? Because exporting a pool is the only way I know of to remove it in TrueNAS.
Try describing exactly what you did as a process to delete the pool. If you can, post some screenshots of your process, without deleting your current pool.
I think this is what I did:
I clicked “Delete Data Set”
I didn’t want to confirm in case I delete the new pool. I think there is an option to wipe the data after confirmation, which I did not check that
I have screen shots, but apparently we can post media (screen shots) on this forum. Unless I’m doing something wron (which I’m prone to do).
Sorry, that should read we CANT" post media.
Anyone have any ideas?
OK, that’s something very different than you said in your OP–a pool is not a dataset. If you deleted a dataset, it’s gone.
If you confirmed the delete, then this is appropriate
Otherwise, if you didn’t, then nothing happened… right?
Imagine how many users would be saved from themselves if this was a real feature of TrueNAS.
It’s still not clear what you did.
Your posts continue to conflate pool operations with dataset operations.
There is no “wipe” checkbox when you delete a dataset. Yet you made a reference to seeing this checkbox.
Without knowing more, it sounds like you went to export your pool.
Maybe you did both? Did you do both? Did you delete (and confirm the deletion) a dataset? Did you then export the pool after you did this?
Walk us through the entire event starting the the original pool and two 500Gb hard drives.
I am guessing you created another pool with the new drives and copied data but I am not sure. You could have replaced the old drive with a new one and let the pool resilver and then done the next drive in the pool the same. Please explain the entire thing in detail.
