How reproducible:
Always


Steps to Reproduce:
1. Setup cluster
2. start clvmd after node has joined cluster


Actual Results:
Clvmd appears to be hanging(RHEL4u6 x86_64). The lvm commands hang and
lvm commands are in 'S' state waiting on syscall connect() to finish.


Expected Results:
clvmd should start, then all the lvm commands should work correct.

This looks like a dup of bz 217895.
Comment 49 Christine Caulfield 2008-03-18 13:29:08 UTC 

*** This bug has been marked as a duplicate of 435341 ***
Comment 50 Christine Caulfield 2008-03-28 13:28:27 UTC 
Corey is still seeing hangs in clvmd even with the patch for 435341.

The fix is below:

Checking in daemons/clvmd/clvmd.c;
/cvs/lvm2/LVM2/daemons/clvmd/clvmd.c,v  <--  clvmd.c
new revision: 1.45; previous revision: 1.44
done
Comment 52 Corey Marthaler 2008-04-01 20:39:30 UTC 
I ran my lock stress test for 4 hours and didn't see a deadlock (I used to see
it right away), so am marking this bz verified in lvm2-cluster-2.02.27-6.el4.
