TrueNAS Scale incorrectly reporting Mixed Capacity VDEVS

[UltraPhysicsNAS]

Hello, After finding I had Mixed Capacity VDEVS I followed some diagnostic steps to see what was wrong with my 1 pool of 10TB drives, and I came upon this link:

TrueNAS Scale incorrectly reporting Mixed Capacity VDEVS

After adding a 4th 6 disk raidz2 to my 3 existing identical 6 disk raidz2 vdevs truenas is reporting they're mixed capacity. I'm on 23.10.0.1. Tried the simplest thing which was to reboot but no change. All of the drives are seagate exos 16tb x16's however one of the new drives is an x18 in...

I have worries about losing the data on this pool, and do not want to proceed further as I am currently experiencing no problems other than a warning message, but I do not want my pool to be problematic in the future because I did not address my situation.

Hey @UltraPhysicsNAS

An upcoming release of SCALE - hopefully 23.10.2 - should suppress this alert for small mismatches of <2GB, and yours looks as if it's only about 1MB.

You shouldn't have any issues in normal operation, but if you have to replace a disk you might have issues if you converted the mirror to a single-disk stripe, as it would "expand to fill" the 1MB-larger partition, and you wouldn't be able to re-mirror it with the same hardware.

Are both of the two disks sda and sdc an identical model?
