description |
When using an nbd root, wait-for-root blocks for 30 seconds before booting continues successfully.
Using Ubuntu Natty, related packages versions:
nbd-client 1:2.9.16-6ubuntu1
initramfs-tools 0.98.1ubuntu9
The wait-for-root call from /usr/share/initramfs-tools/scripts/local:
while [ -z "${FSTYPE}" ]; do
FSTYPE=$(wait-for-root "${ROOT}" ${ROOTDELAY:-30})
# Run failure hooks, hoping one of them can fix up the system
# and we can restart the wait loop. If they all fail, abort
# and move on to the panic handler and shell.
if [ -z "${FSTYPE}" ] && ! try_failure_hooks; then
break
fi
done
I replaced wait-for-root with a sh script that did `set >&2`, here are the relevant environment variables at the time wait-for-root was called:
ROOT='/dev/nbd0'
ROOTDELAY=''
ROOTFLAGS=''
ROOTFSTYPE=''
nbdroot='192.168.0.1,2011'
It's probably worth noting that "nbd0: unknown partition table" was displayed asynchronously 1-2 seconds after wait-for-root was invoked and while it was still waiting. But I tried adding a "sleep 5" as the last line of local-top/nbd, so that the nbd message was displayed a lot before wait-for-root was called, and it didn't make a difference. So I don't think a race condition is involved in this problem.
Temporarily I'm passing rootdelay=1 in the kernel command line to work around the problem. |
[Impact]
Kernel does not generate any events when ndb-client connects /dev/nbd0 devices, therefore it is impossible to monitor/react to the state of /dev/nbd0.
[Fix]
Generate change uevent when size of /dev/nbd0 changes
[Testcase]
* Start udevadm monitor
* modprobe nbd
* use ndb-client to connect something to /dev/nbd0
* observe that there are change udev events generated on /dev/nbd0 itself
[Regression Potential]
There is no change to existing uevents, or their ordering.
There is now an addition change event which will cause systemd to mark ndb devices as ready and trigger appropriate actions
