Description Corey Marthaler 2008-04-29 14:34:41 UTC 
Description of problem:
I saw this on a gulm cluster ater I rebooted all 4 nodes. Only one of the nodes
came back up right away. Two came back up after about 10 minutes and the fourth
is still stuck. Here's where:

Starting ccsd: [  OK  ]
Starting cman:[WARNING]
[WARNING]lustered mirror log:[WARNING]
Starting lock_gulmd:[  OK  ]
Starting fence domain:[WARNING]
Starting clvmd: [  OK  ]

I'll attempt to gather more info.


Version-Release number of selected component (if applicable):
2.6.9-67.0.15.ELsmp
lvm2-2.02.27-2.el4_6.1
lvm2-cluster-2.02.27-2.el4_6.1
Comment 1 Corey Marthaler 2008-04-29 16:43:20 UTC 
Each time, it seem that one of the 4 nodes hangs indefinately, where the other
three do eventually come up. I'll attempt to get a stack trace.

+ initlog -q -n /etc/rc3.d/S24clvmd -s 'clvmd startup' -e 1
+ '[' serial '!=' verbose -a -z '' ']'
+ echo_success
+ '[' serial = color ']'
+ echo -n '[  '
[  + '[' serial = color ']'
+ echo -n OK
OK+ '[' serial = color ']'
+ echo -n '  ]'
  ]+ echo -ne '\r'
+ return 0
+ return 0
+ rtrn=0
+ echo

+ '[' 0 -ne 0 ']'
+ /usr/sbin/vgscan

[DEADLOCK]

Comment 3 Christine Caulfield 2008-04-30 09:20:14 UTC 
There are a suspiciously small number of clvmd threads in that dump. Is it
possible to see what gulm is doing ?

I'm guessing this bz is a dup of 447799.
