https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294077 Bug ID: 294077 Summary: bsdinstall+zfs+mirror+uneven disk sizes is suboptimal Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: phk@FreeBSD.org I threw a 15.0-R on a computer to test it, and since it had two SSDs I chose ZFS+mirror. bsdinstall ignores that the two disks are different sizes: root@mpe:~ # gpart show => 40 250069600 ada0 GPT (119G) 40 532480 1 efi (260M) 532520 1024 2 freebsd-boot (512K) 533544 984 - free - (492K) 534528 4194304 3 freebsd-swap (2.0G) 4728832 245340160 4 freebsd-zfs (117G) 250068992 648 - free - (324K) => 40 500118112 ada1 GPT (238G) 40 532480 1 efi (260M) 532520 1024 2 freebsd-boot (512K) 533544 984 - free - (492K) 534528 4194304 3 freebsd-swap (2.0G) 4728832 495388672 4 freebsd-zfs (236G) 500117504 648 - free - (324K) I think this corner case deserves to be handled better, by sizing the two ada?p4's after the smaller drive (ie: only 117G in this case) so that the rest of ada1 can be used for other purposes. -- You are receiving this mail because: You are the assignee for the bug.home | help
