Previous pool 6x 4tb single vdev

Move data to new pool 4x 3tb single vdev
Add second 4x 4tb vdev
Replace each 3tb disk with 4tb disk

Second 3tbx4 vdev has not expanded

Any ideas would be great on how to expand the vdev so both are 4tbx4

If you truly replaced the 4 x 3TB drives with 4TB drives, and auto expand was enabled, then you can try off-lining and re-onlining each drive in sequence on raidz1-0. Check after the first to verify that it changed size with;
zpool list -v Storage

If it did not change size, please list the output of this command for the first 3TB drive;
smartctl -a DRIVE

Also, in the future, please use CODE tags for command line output, as it make it easier to read.

This sounds similar to a bug I saw reported here recently. Let me see if I can find it. Here it is:

troubleshooting mirror vdev won't expand

I appear to have a similar situation as @ https://www.truenas.com/community/threads/replaced-mirror-with-larger-drives-but-cant-expand-pool.112702/ but that thread ended with inconclusively. I have a pool, tank1. It is 6 disks, 3x 2-wide mirrors. originally, it was 6x 8tb drives. I replaced...

www.truenas.com

The bug's reportedly been fixed, but the report is private so there's no way to see when the fix is due out--I'd expect with 23.10.1 in the next few weeks.

Thanks for the suggestions, will follow the code rule in the future!

For reference: TrueNAS-SCALE-23.10.0.1

I have taken a drive offline and online and used the zpool list -v Storage but the drive size does not increase.
