Expanding Storage pool not working

[Orso]

Hi,

Expanding an existing storage pool is a question that has been asked several times and answered several times as well. But. What if it doesnt work?

I have installed TrueNAS Core TrueNAS-13.0-RELEASE for testing. It's runing in a VM with 1 system disk and 8 datadisks.
I've created a nice Storage pool with 2 drives of 10Gib each and has 7.62GiB available. So far so good.

I then added 2 extra drives, also 10Gib each, and have now 4 drives in the storage pool.
everything looks good. No errors.

I tried hitting "Expand Pool" and hit EXPAND POOL but nothing is happening.
No dedupe or anything fancy set up.

???? Thanks

Bjorn

Sry. Can't edit my post so i'm adding this:

"By added 2 extra drives", I meant going to Storage / Pools, clicking the Pool, then Status, then the 3-dot menu, Extend, selected 1 free drive and hit the EXTEND button".

You're quoting 2 completely different options there... chances are the second one has landed you in a place you may not want to be (and you would have needed to tick the "Force" option to get there)...

I would suggest posting the output from zpool status -v in code tags so we can confirm that your pool is still configured in a safe state.

Btw. Dont' waste tons of brain cycles to assist with this particular problem. It's just a trial-setup to learn how disk-stuff works before I work with real data.

I just don't understand what I am doing wrong.

Seems to be a good idea to get a good feeling about how things work :)

Looks like you just have a 4-way mirror now, so no additional capacity.

If you meant to increase capacity, you wanted to add an additional data vdev
