It's not generally possible to wait for asynchronous scanning to complete, because for USB there is no time limit for devices to appear. You should either poll for the required devices to appear at regular intervals, or use a udev hook to react to their appearance. In either case there should be a configurable timeout or some way to break out and attempt a manual recovery from the missing device.

Dear maintainers of linux, could you please take a look at this issue? Is there any smart way to wait for this asyncronous behaviour?

Right. So you have been hit by the introduction of asynchronous behaviour of the Linux kernel. I have no good idea how to solve it. We need to make the early boot system asynchronous too to avoid such problems. It also affect USB disks and other busses with slow discovery process. :( Happy hacking, Would this behaviour be changed by changing from CONFIG_SCSI_SCAN_ASYNC=y to: CONFIG_SCSI_SCAN_ASYNC=n in the kernel configuration? I will probably leave it set y and just have a custom delay script as I would like to be able to use stock debian kernels even though I usually custom compile them.

Bug#510367: [Pkg-sysvinit-devel] Bug#510367: initscripts: checkfs.sh runs before /etc/modules processed
[Arthur Marsh] When the system boots, checkfs.sh runs before module eata loads, and so fsck is not performed on the filesystems on the SCSI disk. /etc/modules is then processed and the SCSI disk is accessible. Which script is processing /etc/modules on your machine? Can you provide the output from 'ls /etc/rcS.d/'? On my machine, it is done by module-init-tools in the module-init-tools package, and it is started before checkfs.sh.

[Arthur Marsh] After manually observing a reboot, it appears that although module eata is successfully loaded before filesystems are checked, the device files for the SCSI disk are created asynchronously, in my case after the filesystem check script has attempted to check the filesystems on the SCSI disk. Right. So you have been hit by the introduction of asynchronous behaviour of the Linux kernel. I have no good idea how to solve it. We need to make the early boot system asynchronous too to avoid such problems. It also affect USB disks and other busses with slow discovery process. :( Happy hacking, -- Petter Reinholdtsen -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

It also affect USB disks and other busses with slow discovery process. :( Happy hacking, I manually added the following script to execute as /etc/rcS.d/S22sleep-for-scsi #!/bin/sh if (lsmod|grep eata); then echo waiting 5 seconds for module eata to query SCSI bus sleep 5 fi The 5 second wait between module-loading and filesystem checking was sufficient time for the SCSI bus to be queried and device files /dev/sda? to be created. As my system is not a candidate for sub-5-second boot anyway, I don't mind the wait if it means that the filesystems are checked before they are mounted (-:.
