RaidZ2 Expanded - Fix Drive Names?

TrueNAS General
1

I just upgraded to Truenas Scale ElectricEel-24.10.0 and expanded my 6 drive Raidz2 pool to 8 drives, one drive at a time.

However, when I run “zpool status”, it seems that I have lost the friendly “sdx2” names for these new drives. It seems like they should be called “sdh2” and “sdi2”, respectively, but instead they have a really long alpha-numeric string associated with them. Any way to fix this?

The UUID is normal. You rather want to fix the other drives being displayed by drive letter and partition number!

I’m new to some of the behind the curtain workings of all this, can you help me understand why it would be better to change all of the drive names to the UUID instead of the shorter, friendlier names?
