[Bug 518219] New: sm-notify runs before dhcpcd sets hostname

There are two network scripts: - /etc/init.d/network: this is the script referenced via $network and is started before nfs ($remote_fs scripts). It activates only "ifup" interfaces, that don't require an already mounted $remote_fs. Basically normal ethernets, bonds, bridges and vlans. But it does not start WLAN, PPP (ISDN, DSL or whatever) and also not the NetworkManager when enabled. - /etc/init.d/network-remotefs: this is a second network script that starts either the NetworkManager or all the "ifup" interfaces, that require $remote_fs (WLAN, PPP, ...). Except of /etc/init.d/nfs, also the /etc/init.d/nfsserver script calls sm-notify. It does not have any dependencies to $remote_fs: # Required-Start: $network $named $portmap even all it's binaries are in /usr. IMO a bug and it is probably the script calling it before the hostname is set. The question is also, where the interface setting the hostname is started. /etc/init.d/network waits for the mandatory interfaces and also until dhcp finishes. This should work. But when there are two interfaces: one started in network (and used for the nfs mounts) and second one started in network-remotefs that sets the hostname, it is a configuration problem, not a bug. Next possibility are some if-up.d/ifservices or NetworkManager hooks, e.g.: /etc/NetworkManager/dispatcher.d/nfs This script does not care about the interface at all and supports only one interface at all, restarting the nfs client and umounting all... But I don't think that this is the problem, since this script is called very late (network-remotefs => NetworkManager => nfs-hook). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

When the dhcp client needs too long to setup the interface, /etc/init.d/network will continue and report "in background". Common reason is a bridge with enabled STP. Please verify that all your bridges have this two settings in ifcfg-* files: BRIDGE_STP='off' BRIDGE_FORWARDDELAY='0' A bridge with enabled STP may need up to 50 secs before it enables the interface / starts to forward packets, see also: http://tldp.org/HOWTO/BRIDGE-STP-HOWTO/advanced-bridge.html#STP you can tune STP e.g. using BRIDGE_FORWARDDELAY='4' BRIDGE_HELLOTIME='1' BRIDGE_MAXAGE='4' and increasing the timeouts to: WAIT_FOR_INTERFACES="60" DHCLIENT_WAIT_AT_BOOT="30" When the ISC dhclient is in use (not dhcpcd), if may need +15sec: # Note: RFC 2131 specifies, that the dhcp client should wait a random time # between one and ten seconds to desynchronize the use of DHCP at startup. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've been keeping an eye on my openSuSE 11.1 machines (about 15) and they don't show this problem. So I've only seen it on my test machine which is a virtual machine running on vmware-server (on another openSuSE 11.1). I assumed that this problem was the cause of some stale NFS locks on 11.1 clients but that seems to be caused by bug #520311 instead. Running on vmware-server makes it slow which might be what triggers this. I'm sorry I should have mentioned that, but it would be nice if it would work on virtual machines also. eth0 isn't set up as mandatory in /etc/sysconfig/network/config. I've tried doing that but it didn't help. I guess it should be mandatory automatically as a physical interface with STARTMODE='auto'. Anyway, there's only a single ethernet adapter, it has no exotic configuration. I've attached boot.msg and config, dhcp and ifcfg-eth0 from /etc/sysconfig/network.
From the log: I've inserted a loop in the nfs init script just before sm-notify runs. It logs the current hostname and sleeps for 1 second until the hostname is correct.

eth0 isn't set up as mandatory in /etc/sysconfig/network/config. I've tried doing that but it didn't help. I guess it should be mandatory automatically as a physical interface with STARTMODE='auto'.
Yes. When MANDATORY_DEVICES in network/config is not set, physical interfaces are added to the set. The documentation of MANDATORY_DEVICES variable does not have the "boot" option (set automatically when started via init). Without it, there are no mandatory devices -- waiting at boot isn't executed. Further, the network script runs twice with: localfs and remotefs filter. Please use instead: rcnetwork start -o boot debug fake localfs It should look like this (OK, this is more complex setup): # rcnetwork start -o boot debug fake localfs * Modifications by localfs filter: PHYSICAL_IFACES => eth0 eth1 eth2 + = eth0 eth1 eth2 NOT_PHYSICAL_IFACES => br0 br1 + = br0 br1 MANDATORY_DEVICES => eth0 eth1 + = eth0 eth1 MANDATORY_SLAVES => + = VIRTUAL_IFACES => br0 br1 + = br0 br1 CONFIG = INTERFACE = AVAILABLE_IFACES = br0 br1 eth0 eth1 eth2 PHYSICAL_IFACES = eth0 eth1 eth2 BONDING_IFACES = VLAN_IFACES = DIALUP_IFACES = TUNNEL_IFACES = BRIDGE_IFACES = br0 br1 SLAVE_IFACES = eth0 eth1 MANDATORY_DEVICES = eth0 eth1 __NSC__ VIRTUAL_IFACES = br0 br1 SKIP = start order : eth0 eth1 eth2 ; eth0 eth1 __NSC__ ; br0 br1 Setting up (localfs) network interfaces: ifup lo -o rc onboot lo returned 0 done ifup eth0 -o rc onboot eth0 returned 0 done ifup eth1 -o rc onboot eth1 returned 0 done ifup eth2 -o rc onboot eth2 returned 0 done .. still waiting for hotplug devices: SUCCESS_IFACES= lo eth0 eth1 eth2 MANDATORY_DEVICES=eth0 eth1 __NSC__ .. final SUCCESS_IFACES= lo eth0 eth1 eth2 MANDATORY_DEVICES= FAILED=0 ifup br0 -o rc onboot br0 returned 0 done ifup br1 -o rc onboot br1 returned 0 done ifup-route noiface -o rc onboot Setting up service (localfs) network . . . . . . . . . . done
Anyway, there's only a single ethernet adapter, it has no exotic configuration. I've attached boot.msg and config, dhcp and ifcfg-eth0 from /etc/sysconfig/network.
Yes, I don't see anything special in your configs. I guess I know where the problem is: ifup-dhcp does not know when exactly the dhcp client sets the hostname. It may return OK to the network script too early.
