boot log excerpt showing iscsi starting before network and failing (3.31 KB, text/plain)

Description Tim Flink 2011-10-19 21:35:43 EDT
Description of problem:

I did a minimal install (no NM) for F16 i386 and added /opt as a 20G
iSCSI target.

When I boot, iscsi and iscsid attempt to start before networking is up
and the target is not mounted.

Version-Release number of selected component (if applicable):

How reproducible:
Every time

Steps to Reproduce:
1. install F16 with an iSCSI target as /opt
2. reboot
Actual results:
/opt is not mounted on reboot because the network isn't up before the system tries to mount the iSCSI target

Expected results:
/opt is mounted at boot

Additional info:

The only way I've been able to get the iscsi target to mount @ boot is to change either the iscsid or iscsi init script to depend on $network.

Proposing as NTH for Fedora 16 final as it violates the following final release criterion [1]:

The installer must be able to complete an installation using any network-attached storage devices (e.g. iSCSI, FCoE, Fibre Channel).

However, it only affects systems without NetworkManager and doesn't seem appropriate for a blocker.

I am seeing this same issue.
Comment 5 Mike Christie 2011-12-06 17:18:08 EST

I was going to just merge a fix so that network is added to the RequiredStart section of the iscsi init script, but while testing this I noticed it does not help in F16 with the rpms all up to date (I thought this fixed the problem before).

In your setups, do you have network init script setup? Is it linked properly in /etc/rc*.d/ ? Does

chkconfig --list network

show it is setup properly?

If you run

chkconfig network on

does it then work? Is the problem that we want this to be done automatically?

Or in your setups is the network coming up after the iscsi script? If so, could you send the output of

ls -l /etc/rc5.d/*

(replace 5 with your value).

chkconfig --list network

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

Ping, where are we on this? Any chance of a fix for F17?

Comment 8 Nathan G. Grennan 2012-02-03 19:13:22 EST
I found the cause of the bug for me. I use network instead of network-manager, and /var/lock/subsys/network doesn't exist yet, even though the interfaces are up. When I comment out the check, it works.

    # if the network isn't up yet exit cleanly, NetworkManager will call us
    # again when the network is up
    [ ! -f /var/lock/subsys/network ] && ! nm-online -x >/dev/null 2>&1 && exit 3
Comment 9 Nathan G. Grennan 2012-02-03 19:22:54 EST
I just double checked things and found I am wrong on the details, but commenting out the line does fix it for me.

Here is the timing:
Feb  3 16:14:04 proton network[1299]: Bringing up loopback interface:  [  OK  ]
Feb  3 16:14:06 proton network[1299]: Bringing up interface eth0:  [  OK  ]
Feb  3 16:14:08 proton network[1299]: Bringing up interface eth1:  [  OK  ]
Feb  3 16:14:11 proton network[1299]: Bringing up interface eth2:  [  OK  ]
Feb  3 16:14:22 proton iscsi[1359]: Starting iscsi: [  OK  ]

ls -al --time-style full-iso /var/lock/subsys/network
-rw-r--r-- 1 root root 0 2012-02-03 16:14:11.153393551 -0800 /var/lock/subsys/network

So /var/lock/subsys/network does get created right after eth2 comes up, and iscsi comes up 11 seconds later.

I also proved it isn't the line below during testing by changing the exit code for the network line from 3 to 4.

[ $? -eq 0 ] || exit 3

So it all comes down to the line below not working.

[ ! -f /var/lock/subsys/network ] && ! nm-online -x >/dev/null 2>&1 && exit
