It ends up that it is the iSCSI scan is running very slowly, and that the current open-iscsi returns if the scan takes more than 3 seconds (and also leaves an unreaped iscsid process each time). So, it was not that udev was slow here, it was that the iscsi login/scan returned before the scan was even *complete*, so of course there were still udev events in progress after the iscsadm login returned. It took a while to notice since I had udev info (not error ...) logging on, and missed the intermixed scsi discovery output. Plus, iscsid didn't log any errors. -- Patrick Mansfield ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
