SOLVED Boot Vol upgrade: autoexpand?

[depasseg]

So I've been thinking about this, and all I did was use the GUI to replace each drive with the larger one (and then removed the old one). Once I had the 2 larger drives running, I used those steps above to do the expansion.

Code:

[root@freenas1] ~# zpool status freenas-boot  [used to check that everything is healthy and to get the partition names]
[root@freenas1] ~# zpool set autoexpand=on freenas-boot [set option to auto expand]
[root@freenas1] ~# zfs list freenas-boot [confirm space prior to expansion]
[root@freenas1] ~# zpool offline freenas-boot ada2p2  [removes the first partition from the pool (substitute with your first drive)]
[root@freenas1] ~# zpool online -e freenas-boot ada2p2 [adds the partition to the pool, with the expansion option set]
[root@freenas1] ~# zpool offline freenas-boot ada3p2 [removes the second partition from the pool (substitute with your 2nd device)]
[root@freenas1] ~# zpool online -e freenas-boot ada3p2 [adds the partition to the pool, with the expansion option set]
[root@freenas1] ~# zpool status freenas-boot [check the status]
[root@freenas1] ~# zfs list freenas-boot [check the size and compare to the beginning]
[root@freenas1] ~# zpool set autoexpand=off freenas-boot [remove option to auto expand]

Thanks. I followed those instructions and I got it working. Unfortunately it turns out it wasnt right for what I wanted to do so I ended up redoing the freenas installation from scratch. lol. Thanks anyway.

This worked for me as well with a slight tweak. USB sticks listed as da2p2 and da3p2 but when I tried to offline by using that I was getting "cannot offline da3p2: no such device in pool"
Thanks to this link I used vdev guids to run the command and it worked.

Code:

[root@freenas] ~# zpool offline freenas-boot da3p2
cannot offline da3p2: no such device in pool
[root@freenas] ~# zdb|grep -B 1 gptid/cbcbef8f-6d18-11e6-9928-002590981832

Very interesting bug report and oracle docs. Looks like it's possible to move to the bigger devices, then either set autoexpand=on (temporarily to expand then set to off), or zpool online -e.
http://docs.oracle.com/cd/E19253-01/819-5461/githb/index.html

Can confirm that mounting with expand on does do the trick. IIRC you can actually issue the "zpool online -e" command to a pool which is already online in order to expand it.

I did this on my bootpool when I expanded to 16GB USBs from 8GB. I didn't want to have auto-expand on in case I round-tripped through larger devices in the future.

I was trying to find some solution for expanding my boot volume, but I'm not sure, which way to go.
From start I had 4GB stick on FreeNAS, then I created mirror to move on bigger SSD 120 GB did a sync and removed 4GB stick. After some years I noticed now that boot size is still 4GB, so I tried to set autoexpand=on for boot pool but with no effect (if I get it right I have to change boot device before autoexpand-on right?). I don't need to have system on two drives, it's only home NAS for photos and movies, so:
1) what is the best way to use whole space on my system SSD?
2) how do I get rid off of notification: "Boot Pool Status Is DEGRADED" when I removed the 4GB stick from mirror several years ago?

Thanks a lot for some suggestions!

Thanks depasseg,

This code block worked perfectly for expanding the boot-pool from 2x4GB sticks to 2x32GB sticks. I know iXSystems no longer recommend USB sticks for the boot-pool, but mirrored in a home set-up, I'm prepared to take the punt.

The only change needed was freenas-boot has been modified to boot-pool in TrueNAS Core 12.

Cheers.
