[Linux-cluster] GFS crashing on 2.6.18.6

[Jaap Dijkshoorn]

People,

We have build the stable GFS tree againt 2.6.18.6. After we executed
ccs,cman, fenced and clvmd we tried to mount the GFS filesystems, with
the following result:

CMAN: sending membership request
CMAN: got node ifs4
CMAN: got node ifs3
CMAN: got node ifs2
CMAN: got node ifs1
CMAN: quorum regained, resuming activity
