[Ocfs2-users] DMesg error on startup ...

Thu Dec 7 14:00:04 PST 2006

Ok, it is not about 'ended'.

What happen, more likely:

- Linux runs network service. It enables interfaces (btw, some interfaces comes by Hot PlugIn daemon after in, asyncronously)
- ifconfig reports interface UP. In reality, ethernet is in spanning-tree negotiation mode (so it cant send/receive packets next 30 seconds)
- network service exists with 0 return code (because it did everything). So system proceed with next service(s)
- it starts o2cb in 2 - 5 seconds after it.
- so, next 20 - 30 seconds o2cb cant communicate (because switch did not finish spanning tree negotiation yet - it have 30 or 40 second shold time)
and so  it fail.
- when you run it in the very end, it can work.

So, 
(1) fix switch config
OR
(2) add 'wait when ping will work' into the network script (or better add one more service which do it)
OR
(3) add sleep 40 into the o2cb 

No one oif these methods is not bypass.

For 'order', see skeleton file in /etc/init.d . But order is corerct out of the box (at leat, relating to the network - it is not correct if you use iSCSI for example).

  thanks for you offer, but this like the addition of "mount -a" in the rc.local are ways to bypass the problem.
  Is there a way to prevent a init service with lower preference to start before the init service with higher prefernce ended? like s25ocfs2 will start only after s24o2cb will end ...

    Btw, check that your network ports are in fast-spanning-tree mode (don't wait 30 seconds when connected). On the Ethernet switch.

      I wasn't exact about the previous mail.
      The real problem is that o2cb does not complete his startup before the ocfs2 start his.
      the order is as you mentioned s24o2cb -> s25ocfs2.
      The problem is as I wrote before: some of te FS are mounted and other doesn't, it depends on how fast the o2cb starts.
      So is there any way fixing this problem ( other than adding " mount -a" to the rc.local ) ?

        Hi,
        I am encountring with the same problem, I double checked and the startup order is as u mentioned, i.e. S10network -> S24o2cb, but still some ocfs2 FS tries (and failes) to mount before the network comes up.
        Other FS which tries to mount after the network comes up succeed, the FS which succeed to mount change from boot to boot ( depends on how long it takes to the network to comes up ).
        Is there any way to resolve this problem other then adding "mount -a" to the rc.local ?

        10x

          The startup order should be... ==> network, o2cb, ocfs2.
