Hello, I've run into a strange behavior of gpart I can't interpret. Maybe you can give me some insights?
When I try to create a partition, aligned to 4k gpart outputs strange notice
1. It this partition aligned to 4k? (it looks like)
2. Why it prints this notice?
abishai@gamma:~ % gpart show nda0
=> 6 244190635 nda0 GPT (932G)
6 244190635 - free - (932G)
When I try to create a partition, aligned to 4k gpart outputs strange notice
abishai@gamma:~ % doas gpart add -t freebsd-zfs -a 4k -l data0 /dev/nda0
nda0p1 added, but partition is not aligned on 32768 bytes
Code:
abishai@gamma:~ % doas smartctl -a /dev/nvme0
smartctl 7.4 2023-08-01 r5530 [FreeBSD 14.2-RELEASE-p1 amd64] (local build)
