Hi, everyone I use kernel 2.6.15-rc7 and the latest STABLE cvs branch of GFS when the newest kernel is 2.6.15-rc7。 I've started a GFS cluster with 4 nodes, but after about 4 days, the cluster did not work.I found the /var/log/messages as follows: <-- Mar 28 15:31:29 nd05 kernel: d 1 locks Mar 28 15:31:29 nd05 kernel: gfs-sda1 update remastered resources Mar 28 15:31:29 nd05 kernel: gfs-sda1
