Description of problem:
A restart of iscsi.service modifies records node.startup value from:
node.startup = automatic
to:
node.startup = onboot
This change hangs shutdown process since the session is never logged out.
Version-Release number of selected component (if applicable):
Both:
iscsi-initiator-utils-6.2.0.874-7.el7.x86_64
iscsi-initiator-utils-6.2.0.874-10.el7.x86_64
How reproducible:
very
Steps to Reproduce:
1. Setup iSCSI initiator
2. log in to target for non-root device
3. systemctl restart iscsi.service
Actual results:
# grep -R "node.startup" /var/lib/iscsi/nodes/*
/var/lib/iscsi/nodes/<target>/<ip>/em1_iface0:node.startup = automatic
/var/lib/iscsi/nodes/<target>/<ip>/em1_iface1:node.startup = automatic
# systemctl restart iscsi.service
# grep -R "node.startup" /var/lib/iscsi/nodes/*
/var/lib/iscsi/nodes/<target>/<ip>/em1_iface0:node.startup = onboot
/var/lib/iscsi/nodes/<target>/<ip>/em1_iface1:node.startup = onboot
# reboot
Stuck at "Rebooting"
Expected results:
Manual restart of iscsi.service does not prevent shutdown/reboot
Additional info:
The iscsi.service calls script `iscsi-mark-root-nodes`:
---
ExecStart=/usr/libexec/iscsi-mark-root-nodes (code=exited, status=0/SUCCESS)
This script does not perform any root dev verification and alters all node record:
<snip>
while read t num p target flash; do
# strip tag number from portal, keep "ip:port"
portal=${p%,*}
transport=${t%:}
$ISCSIADM -m node -p $portal -T $target -o update -n node.startup -v onboot
</snip>
While is not ideal to restart iscsi.service, customer is performing this to reload altered iscsid.conf vs using `iscsiadm ... -o update` cli.
I'm moving the special handling of boot sessions (set node.startup to onboot and force starting of iscsid for session recovery) out of iscsi.service and into it's own iscsi-onboot.service (which will have RefuseManualStart set as well)
