Hello, I had ran "modprobe gfs" and I see by lsmod the the gfs module is loaded. also I had verified that under /lib/modules/MyKernelVersion/extra/gfs/ there is gfs.ko. Then I try: gfs_mkfs -p lock_dlm -t myCLuster -j 32 /dev/cciss/c0d1p2 mount /dev/cciss/c0d1p2 /mnt/gfs The errors I see in the console are: /sbin/mount.gfs: lock_dlm_join: gfs_controld join error: -22 /sbin/mount.gfs: error mounting lockproto lock_dlm The error I see in kernel log is: gfs_controld[32629]: mount: not in default fence domain I want to add that the cman service is started succesfully as the kernel log shows. I want also to add that "service cman start" performs modprbe of gfs2 module and not gfs module ! Namely, I ran rmmod gfs; then, after : service cman stop and rmmod lock_dlm rmmod gfs2 running lsmod | grep gfs2 shows that no gfs2 is loaded, and after "service cman start" I see by lsmod | grep gfs2 gfs2 522965 1 lock_dlm which means that starting the cman service performed modprobe/insmod of gfs2 and lock_dlm Is this how things should be? rgs, Ian On 9/1/07, Wendy Cheng <wcheng@xxxxxxxxxx> wrote: > Ian Brown wrote: > > > - Hello, > > I had installed RHEL5 on two x86_64 machine on the same LAN; afterwards I > > had installed the RHEL5 cluster suite packege (cman-2.0.60-1.el5) and > > openais-0.80.2-1.el5. > > > > > > I had also installed kmod-gfs-0.1.16-5.2.6.18_8.el5 and gfs-utils > >and gfs2-utils. > > > > I had crated a 2-node cluster and started the cman service OK on both nodes. > > > > Now I tried to create a gfs partition with gfs_mkfs (with -p lock_dlm) > > and mount it, and I got errors when trying to mount it (this errors > >talk about > > gfs_controld). > > > > > You didn't include the error message here ?
