Description of problem:
If, before starting smartd, I plug an USB storage device (usually seen as
/dev/sda1), smartd won't hapen to start:

[root@dhcppc0 julo]# /etc/rc.d/init.d/smartd start
Starting smartd:


If, however, I start smartd without any USB storage device plugged, it starts
without problems.

Note: removing the USB storage device while smartd is attempting to start
doesn't help.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.plug an USB storage device
2.type /etc/rc.d/init.d/smartd stop
3.type /etc/rc.d/init.d/smartd start

Actual Results:  It hangs forever...

Expected Results:  It should start.

Additional info:

I have disabled kudzu in this runlevel. But I don't think it's revelant...

We are aware of this problem and are looking for a fix.  The underlying
problem is that USB drives only implement a subset of the mandatory SCSI
command set.

For the moment you can work around this by setting up /etc/smartd.conf so
that it does NOT scan for devices.

smartd says that it starts on my federa but it takes two minutes to
start the daemon.

When I start with the usb storage removed it takes a second :)

if you need the logs just let me know ;)
Comment 3 Bruce Allen 2003-11-09 15:26:15 EST

Currently, the only solution is to modify /etc/smartd.conf, so that you  
do NOT scan devices.  Then, explicitly list the devices that you want
to monitor.  Do NOT list your USB storage device.
Comment 4 Bruce Allen 2003-11-20 09:27:34 EST
This is fixed in the smartmontools 5.25 development/testing release
and in subsequent releases, including the 5.26 stable release.

The problematic USB devices return some incorrect SCSI length data.
smartd/smartctl now detect this and exit before sending SCSI
commands that will hang the process.
Comment 5 Dave Jones 2005-04-21 22:52:14 EDT
this should be fixed in current trees, as FC3 has 5.33
