nice, followed the advice to disable uas due to stalling/performance/logspam trouble on the #odroid which turn now gives me full smart readings and ... well ...
hm do i read correctly that its quite common to get oops with #btrfs on #odroid machines? at least coming from manjaro, now being on debian with kernel 6.3, i can reproduce. its fine for very lightweight operations but its not a fan of rsync or timemachine.
alright, moved to ext4 with mdadm as (assuming) btrfs seems broken on all images if found and ... that actually booted. boy can it be frustrating to find working isos for the c4 (that also ship with newer kernels). i am back on manjaro now.
for zfs on the 5tb storage, the thing wouldnt have enough ram i think.
