[Linux-cluster] can not mount GFS, "no such device"



Hello, everyone:

I failed to mount GFS with error message "no such device". But I have
confirmed that the device exists and all relevant kernel modules have
been loaded.

I am using RH5.4 and no any customization at all.

Would someone kindly help?
