[Bug 834518] New: When ifplugd enabled for interface, mount.nfs may fail
https://bugzilla.novell.com/show_bug.cgi?id=834518 https://bugzilla.novell.com/show_bug.cgi?id=834518#c0 Summary: When ifplugd enabled for interface, mount.nfs may fail Classification: openSUSE Product: openSUSE 12.3 Version: Final Platform: x86-64 OS/Version: openSUSE 12.3 Status: NEW Severity: Minor Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: Sergey.Klyaus@Elcom.SPb.Ru QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0 The cause of fail is that ifplugd doesn't wait until link is up, and due to parallel nature of systemd, it starts network mounts.

Reproducible: Always Steps to Reproduce: 1. Set up network interface using ifplugd 2. Create nfs mounts from remote server 3. Reboot Actual Results: Client fails to mount shares Expected Results: Client successfully mounts them Setting STARTMODE='onboot' in ifcfg file fixes it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Yes.
