I took the plunge and upgraded from DF latest to EE latest 
Both my systems are “pure NAS” systems , no apps installed.
It seems like it went well , but i noticed two alerts. When logging into the new EE.
1: I saw this alert on both machines:
1 API login failures in the last 24 hours: (username=root,session_id=41fc7f5d-0030-4a9c-8e38-a3e1eeaxxxxx,address=127.0.0.1)

Edit: The below appeared on my primary unit, after two reboots
Now they are consistent.
This forum really need a StrikeThrough button/feature.
2: This is strange, as i just saw it on my “Backup NAS” , not the primary.
New ZFS version or feature flags are available for pool 'Rust-Pool1'. Upgrading pools is a one-time process that can prevent rolling the system back to an earlier TrueNAS version. It is recommended to read the TrueNAS release notes and confirm you need the new ZFS feature flags before upgrading a pool.

It’s my first “Major upgrade” , so i’m a bit green here.
Both machines was installed in Q4 2024 - With DF 24.03
Then upgraded to 24.04 and then to latest 24.04.02.5 (I think/current latest).
I read about the ZFS Upgrade in the RN. And that if I apply it i cant do a fallback.
But why doesn’t that alert show up on the Primary unit ??
Has it been “autoupgraded” or ??
The backup uses 5 “old WD 4-TB and one new WD 4-TB”, but i expect them to be zfs initialized during install. Even though they have been used before.
How do i see what ZFS featureset i currently have on my VDEV … Or is it Pool ?
/Bingo
Ps:
I have no idea how to upgrade ZFS to latest featureset , or if i need to ??
Is it the upgrade button here ??
Pps:
Why do i just get ZFS upgrade alerts on my “RustPool” , and not on my SSD Pool ?
Edit: I just got on my ssd pool now.
Seems like ZFS version check is a tad slow to detect.
