nfs이용한 두대의 클러스터중 클라이언트의 reboot시 에러...

답변 감사합니다.
제가 외부에 나가있어서 오늘에야 봤습니다.
말씀하신대로 했더니, rpc error 101이라고 하면서 화면을 가득채우며 멈춰버리는건 사라졌네요..^^

그런데 reboot이나 종료시에 아래와같은 메시지가 나옵니다.

Please stand by while rebooting the system...

그리고는 다시 부팅하면 아주 정상적으로 부팅되구요...

다시한번 질문 드립니다.

1. 한 node에서 nfs 마운트된 디렉토리에 화일을 생성하고 다른 node에서 rsh로 생성된 화일을 확인할수 있습니다.
이것이 되면 nfs가 정상적으로 작동된다고 보면 되는건지 궁금합니다.

2. 위 메시지에서 failed의 원인을 모르겠습니다.
아래는 /etc/exports file 입니다.

/tftpboot/192.168.2.2	192.168.2.2(rw,sync,no_root_squash,no_subtree_check)
/usr			192.168.2.2(rw,sync,no_root_squash,no_subtree_check)
/opt			192.168.2.2(rw,sync,no_root_squash,no_subtree_check)
/var			192.168.2.2(rw,sync,no_root_squash,no_subtree_check)
/home			192.168.2.2(rw,sync,no_root_squash,no_subtree_check)

아래는 클라이언트의 /etc/fstab 입니다.

192.168.2.1:/tftpboot/192.168.2.2    /	nfs	rw,defaults	0 0
192.168.2.1:/usr		/usr		nfs	rw,defaults	0 0
192.168.2.1:/home		/home		nfs	rw,defaults	0 0
192.168.2.1:/opt		/opt		nfs	rw,defaults	0 0
none			/dev/pts		devpts	gid=5,mode=620	0 0
none			/proc		proc	defaults		0 0
none			/dev/shm		tmpfs	defaults		0 0
/dev/fd0			/mnt/floppy	auto	noauto,owner,kudzu 0 0

portmap, nfslock, nfs 정상작동 하구요..

지금 MPICH를 올려 앞으로 갈길이 먼데 여기서 자꾸 나아가질 않습니다.

도와주십시요... :oops:
