Assuming you ran this from the web UI under System → Shell, you can open the same shell and use the ls command to determine if the file is in the default directory.
You can then use the rm command with the filename, such as rm seqread
It was indeed showing by using the ls command and I was able to remove it via rm seqread.0.0. Now I have all the empty space I’ll never going to use back again.
That’s actually a good idea, I could set the interface to French, so the next time I screw something up I just say “Oh, la la…” instead of “oh, ffs…”.
I’m at that point where Truenas Scale is a new thing, so I try to get an understanding about how it works. This was the first shell command I used in about 20 so far that didn’t work as intended, although I must admit I kinda pasted it blindly. Usually I try to first have a basic understanding of every parameter.
What I personally learnt, besides of course what @Protopia said, is that you need to target your desired pool/datasets with commands of these nature.
Off I go, let me see if I can find some commands that will download me more RAM and convert my HDDs to SSDs.
