Should I offline my degraded pool?

TrueNAS General
1

Hi all,

I am running TrueNAS Scale Dragonfish 24.04.2 with two pools, one being a two-wide SSD mirror for NextCloud and VMs, the other being a six-wide RaidZ2.

One of my drives in the RAIDZ2 pool failed and I sent it for replacement after putting it offline. I shut down the server since but now need to get my cloud running again. The replacement drive isn’t coming for at least a week.

Would it be a good idea to put the degraded pool offline before being able to resilver it?
If that changes anything, the pool is locked on startup which I assume would prevent any writes on it but I might be naive.
Thanks.

AFAIK, resilvering only happens online–there’s no real way to interact with an offline pool. So no, it wouldn’t be a good idea.

Maybe I wasn’t clear.
My idea is to offline the degraded pool and unplug the disks to keep using my NAS without it whilst waiting for the spare drive.
Then once the spare drive arrives, plug the drives back including the new one and online the pool, and resilver.

It’s RaidZ2.

I’d just keep on using your system until the replacement arrives.

Worry about it if a second drive fails… which most likely won’t happen.

the post right above this would be the normal answer BUT if you want to take the pool offline and not be used at all

Storage tab Export/Disconnect

The pool would then be offline… you could even powerdown/remove the disks after that

Later
use import pool

when ready to bring it back… it will show as an importable pool provided you did not click the wrong boxes on that first popup… (Which is why not doing this is generally the correct idea)
