Hi Thank you Devrim. However, I think that the kernel version is correct. Because when I installed GFS-kernel-smp-2.6.9-60.3.i686.rpm, the kernel of this version was demanded. And, I will check cman-kernel that Patrick pointed out. > > FATAL:Error inserting gfs > > (/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs/gfs.ko ): > > Unknown symbol in module, or unknown parameter(see dmesg) > > > > And, the output of dmesg is as follows. > > Lock_Harness 2.6.9-60.3 (built Oct 11 2006 18:31:11) installed > > AFAICS the kernel module version does not match your kernel version. > Please check and install correct versions.
