Package: open-iscsi
Version: 2.0.874-7.1
I've created a VM to test the feasibility of a particular configuration
and wound up running into a case that open-iscsi does not consider
during shutdown: if an iSCSI session provides a device that is used as
part of an md-raid device, then the open-iscsi shutdown scripts will not
notice this and terminate the iSCSI session anyway. This causes the
iSCSI device to be kicked from the raid device. On boot, because the
device was kicked out, it will not be re-added automatically. ("mdadm
$MD_DEVICE --re-add missing" fixes this, but must be run by hand.)
The current workaround I am using is to set
ISCSI_ROOT_KEEP_ALL_SESSIONS_AT_SHUTDOWN=1 in /etc/default/open-iscsi.
It would be nice if open-iscsi looked through md-raid layers and avoided
stopping sessions that provide a device used by _any_ active md-raid
device, as not doing so requires manually re-adding the iSCSI device to
the array next time it is assembled.
