https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204976 Bug ID: 204976 Summary: zfs root fails to boot raidz1 raidz2 raidz3 Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: mikhail.rokhin@gmail.com RAIDZ1 failure: FreeBSD/x86 boot Default: zroot/ROOT/default:/boot/kernel/kernel boot: ZFS: i/o error - all block copies unavailable Invalid format Can't find /boot/kernel/kernel RAIDZ2 failure: No. Boots fine. RAIDZ3 failure: No. Boots fine. Stripe & Mirroring boot fine. There's some error when changing from RAIDZx to Mirroring and choosing 2 disks - autoZFS fails to partition. Probably ZFS-sys counts all existing disk and fails due to uncleared disks left, misunderstanding 2 chosen and cleared vs. left with uncleared zroot from previous RAIDZx partitioning. So it turns out that ZFS counts & reads all disks, whatever quantity chosen in menu. It's failure misbehaviour. 5x 16Gb disks via SAS lsilogic. i386 - the same RAIDZ1 failure. ZFS shows very low speed (amd64 1000-5000 files/sec, i386 50-100 files/sec). But three disks RAIDZ1 boots fine, 4 disks - boots fine. Why do 5 or 9 or more disks lead to failure then? RAIDZ2 and RAIDZ3 fails to boot when chosen 11 disks. -- You are receiving this mail because: You are the assignee for the bug.
