Error "cp: preserving permissions > Operation not permitted"

[derpuma]

Script stops after creating the first *.blanace file. Any help what to do?
I am logged in as root user of my truenas 24.10.

Did you ensure your user has the required permissions?

I have exact the same issue, also running truenas 24.10
running the script as root.
I looks like it did preserve permissions, but it stops with the error: operation not permitted.
.balance file as same rights and size as original

Solved In truenas you can change under dataset details:

it needs to be set to passthrough

Hi @markusressel , thanks for the reply.
I am using the script as root, so the script should have all permissions to write to the nas.
I have no problem to cp or touch files in the same directory with the root user at all.
No ideas so far but I will try the "passthrough" tip from @qwerk qwerk and report back!

Thanks a lot, ACL with passthrough did work!
