Hello all,
I am using CURRENT, experimenting with ZFS, and I am getting a
consistent crash with any substantial file system IO. It usually takes
just a few seconds of heavy use.
I have a standard ATA drive connected via ATA100 off the
motherboard that I use as the source of files (ad1s1a, UFS2).
The ZFS file system sits on a ZFS pool created with:
zpool create zp0 raidz /dev/ad4 /dev/ad6 /dev/ad10 /dev/ad12
The devices ad4 and ad6 are connected via a PCI SATA card:
atapci0: <Promise PDC20575 SATA150 controller> port
0xec00-0xec7f,0xe800-0xe8ff mem
0xdffff000-0xdfffffff,0xdffc0000-0xdffdffff irq 11 at device 5.0 on pci0
And ad10 and ad12 are on another PCI SATA card:
atapci1: <SiI 3112 SATA150 controller> port
0xdc00-0xdc07,0xd800-0xd803,0xd400-0
xd407,0xd000-0xd003,0xcc00-0xcc0f mem 0xdfffec00-0xdfffedff irq 9 at
device 8.0 on pci0
When not being used as part of the ZFS pool, each of the four drives
(disks/devices) can be read/written at any rate and load without
creating instability (thank you FreeBSD). Before trying ZFS I had
standard UFS2 file systems on each one.
When the crash occurs, the following appears on the console (typed in):
---begin console message---

---end console message---
The output of dmesg for my machine is attached. It's a MSI motherboard
with 5PCI slots and a Athlon XP 1800+ with 768MB RAM. Happy to
provide more information (crashdumps?) to help solve the bug.
ZFS is so cool, it will be great to have it stable on FreeBSD.
You can email me at thede@loder.com (there might be a challenge since I
use Boxbe, but even if you decide not to take it, I'll search for your
message so I can reply).
Cheers,
Thede
