Bug ID: 222007
Summary: Deadlock at shutdown time between zfs and usb when
using usb stick as cache device
Product: Base System
Version: 10.3-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Situation: system is booting from a zfs pool configured with two usb sticks as
L2 cache devices.
Observation: at shutdown time, after hard-disks are stoped and uptime duration
is printed, usual usb shutdown messages are not printed and the system never
powers itself off. When the same sticks are pluged in the same host but are not
part of the root pool, the system goes to power off as usual.
I suppose there is a deadlock between zfs and usb: zfs keeps references to
those two devices and usb waits for the devices to be liberated before winding
down.
