network restart with DHCP breaks
Last modified: 2014-03-16 23:11:51 EDT
Description of problem: I have a usual setup: one wired eth0 card. When I have problems with network, "service network restart" fails, while "service network stop" and "service network start" always does work. (The starting conditions were the same in both cases.) The error message says that "another instance of dhclient is running". Version-Release number of selected component (if applicable): 8.60-1 I think the manual variant works because of the delay caused by typing "service network start" on the keyboard. Would it make sense to wait a second or two between the start and stop? (Attached please find a proposed patch.)
Created attachment 289781 [details] sleep during network restart
If there's really a delay issue here, that should be fixed at the source rather than an arbitrary sleep. Needs more investigation.
Would this be related? Restart are always reported as "FAILED" but network is working correctly anyway? The difference is that stop/start doesn't help here. dhclient-3.0.6-10.fc8 initscripts-8.60-1 [root@localhost ~]# ps -eaf | grep 5671 root 5671 1 0 22:55 ? 00:00:00 /sbin/dhclient -d -sf /usr/libexec/nm-dhcp-client.action -pf /var/run/dhclient-eth0.pid -lf /var/run/dhclient-eth0.lease eth0 root 5720 3046 0 22:55 pts/1 00:00:00 grep 5671 [root@localhost ~]# /etc/init.d/network stop Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] [root@localhost ~]# ps -eaf | grep 5671 root 6002 3046 0 22:55 pts/1 00:00:00 grep 5671 [root@localhost ~]# ps -eaf | grep dhclient root 6005 3046 0 22:55 pts/1 00:00:00 grep dhclient [root@localhost ~]# /etc/init.d/network start Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0...dhclient(6170) is already running - exiting.

(In reply to comment #5) > is this problem happening yet? Thank you for your cleanup work. Unfortunately, I'm not able to test this right now. Let's close it.
Actually, a short power outage encouraged me to do a quick test; I cannot reproduce it any more. Let's suppose it's fixed.
