Package: base
Severity: important
When using iSCSI devices with multipathd, the open-iscsi boot script is started
before multipathd, hence the system tries to mount _netdev devices before
multipath is up-and-running. Thus my iSCSI devices are not mounted at boot time
and need thus be mounted manualy, which is not a handy thing to do for /home
I created a new script called /etc/init.d/mountnetdev, which can be run with
start|stop to mount/umount all _netdev devices or one can use the stop with a
subsystem to stop only part of the mounts.
One important note: the script is in a very early stage, and still requires
bash since dash does not support ${var:x:y}. In the open-iscsi script I
replaced umountiscsi.sh with: mountnetdev stop iscsi
In /etc/rc2.d I created a symlink S23z-mountnetdev so the script is started at
boot after all _netdev required daemons are started.
Hope this helps to make Debian an even better distro.
Greetings,
Dennis Leeuw
