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 at FreeBSD.org
Reporter: mikhail.rokhin at 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.
