udev events for iscsi

udev events for iscsi

[Gionatan Danti]

Hi all,
I have a question regarding udev events when using iscsi disks.

By using "udevadm monitor" I can see that events are generated when I 
login and logout from an iscsi portal/resource, creating/destroying the 
relative links under /dev/

However, I can not see anything when the remote machine simple 
dies/reboots/disconnects: while "dmesg" shows the iscsi timeout 
expiring, I don't see anything about a removed disk (and the links under 
/dev/ remains unaltered, indeed). At the same time, when the remote 
machine and disk become available again, no reconnection events happen.

Is this the expected behavior? Can be changed? Should I ping the 
linux-scsi list instead?
Thanks.

Try asking the linux-scsi developers, as they know what should happen
here more than anyone.
