[Linux-cluster] how to recover from process_recovery_barrier status=-104



My cluster went down pretty hard, in that I had to hard reboot several
machines, and now the fence daemon won't come up.  I run:

$ ccsd && cman_tool join -w 
$ fence_tool join -w -j 15 -D
blade02:~ # fence_tool join -w -D -j 15
fence_tool: wait for quorum 1
fence_tool: get our node name
fence_tool: connect to ccs
fence_tool: start fenced
fenced: 1122003465 our name from cman "blade02"
fenced: 1122003465 delay post_join 15s post_fail 0s
fenced: 1122003465 added 14 nodes from ccs

and it hangs there forever until I hit ^C.  

On one of the surviving machines, I see (dmesg):

SM: 00000001 process_recovery_barrier status=-104
CMAN: node blade03 has been removed from the cluster : Missed too many 
heartbeats
SM: 00000001 process_recovery_barrier status=-104
CMAN: node blade06 has been removed from the cluster : Missed too many 
heartbeats
SM: 00000001 process_recovery_barrier status=-104
CMAN: node blade09 has been removed from the cluster : No response to 
messages
CMAN: bad generation number 371 in HELLO message from 1, expected 370
CMAN: removing node blade08 from the cluster : No response to messages
CMAN: removing node blade07 from the cluster : No response to messages
CMAN: quorum lost, blocking activity
SM: 00000001 process_recovery_barrier status=-104

Is there a way to recover (restart gfs) without having to reboot this
last machine?  

thanks,
dan

p.s.  here's some more info:
