Thank you!
I was thinking that I should try reinstalling with “EFI only” in BIOS.
There appear to be issues with SSD’s still reported on the Btrfs homepage(s). It almost reads as if Btrfs development has stalled a bit in that regard.
Rotating drives appears to be the only “guaranteed” way to get self-error-correction with Btrfs (from Btrfs home page).
I did learn about avoiding “secure boot support” (the hard way!). But thanks for mentioning it!
- I’ve never seen OpenSuSE self-enable “secure boot support” before! But, oddly, this install with Btrfs raid, it did self-enable it. I had to manually disable it. WEIRD!! (This may be an glitch in the installer code?)
BTW: I’ve been installing/using OS on many machines/servers since OS11 or thereabouts. I’m listed as an “Explorer Penguin” b/c I didn’t update my profile when this forum changed it’s website a year or so ago. (OTOH - I never really became a guru or a wizard or anything like that.)
