Ah, I see. Check out your distros udev rules too. open-iscsi does not distribute any, but some distros might add them. I think udev itself has its own iscsi rule, but I am not sure what various distros do. And I am not sure, but if you updated kernels then it might be due to a change in how the core driver model code works and that might throwing off the udev rules. Sometimes sysfs might change on the iscsi/scsi/block lyaer in a way we have no control over and sometimes older udevs do not handle it. And so you might have to update udev. -- You received this message because you are subscribed to the Google Groups open-iscsi group. To post to this group, send email to open-iscsi@googlegroups.com.
