Hi reza !!
I too had the same problem... the node completes every
step till displayin -> this is node xx** node setup
successfully...
i guess some problem due to loadin the libraries (the
lib might be missin in path or something) or unable to
load the module that u had specified in config.boot /
node_up. did u try checkin the logs at
/var/log/clustermatic/node.xx ??
regardin mountin the nfs thing... well Michal
Jaegermann had sent an updated version of the script
than wot u r usin with some minor fixes. try usin
that.. i carried out the steps manually like copyin
the modules to the node (to the exact path), i guess
there were three modules sunrpc, lockd and nfs. load
sunrpc and do the mkdir and mount as specified. the
rest u can load usually with modprobe. copy the other
daemons if needed.
Regards,
Jon
