I noticed that the init.d script is not mounting my iscsi device listed in fstab as a _netdev.
The problem seems to be that the properly contacted target is not yet in the /dev tree when mount is called

I added a tiny sleep 0.1 before the mount call and got rid of my problem

Here the patch for /etc/init.d/open-iscsi:
128c128
< 	if mount -a -O _netdev >/dev/null 2>&1; then
---

That's an okay workaround but not the best solution. Do you have
/dev/.udev ?

I ask because the check we do in Squeeze is based on the presence of
/dev/.udev. Not the best one. If that path is not existent, we do not
settle for devices. Apart from that, I cannot see anything else causing
the issue.

Do you have the resources to check the same on the current version in
Wheezy / Sid ?

Hi Ritesh,
called "udevdam settle" manually. This one returns but the dev tree is
still not complete, i.e. /dev/sdb does not exist yet when it's time to mount

BTW, sleep 1 is more reliable than sleep 0.1 I found out - and yes, I agree
that this is not the best solution

This cannot be tackled using random sleeps. If there is really a bug, we
need more efficient rules in udev to handle the block devices.

Correct.
The real bug is that you are trying to synchronous operations in
a process which is asynchronous. You need to mount these block devices
using udev rules.
OTOH, this may be solved more generally by init scripts, have a look at
upstart and systemd.

Then we don't have much choice. A udev rule can be cooked up, but that
would be very specific.

Or else you could do a test with the newer init systems and see if that
serves your purpose
