NFS Permission denied - Linux

快被搞瘋了，兩個月前還正常的

現在 Permission denied 就是 Permission denied

明明showmount看的到

[root@node5 ~]# showmount -e server.cluster
Export list for server.cluster:
/home *
/disk1 *

檢查主機端的exports跟hosts也沒問題

[root@server ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fai
127.0.0.1 localhost localhost.localdomain
192.168.1.102 node2.cluster
192.168.1.103 node3.cluster
192.168.1.2 server.cluster
192.168.1.104 node4.cluster
192.168.1.105 node5.cluster

[root@server ~]# cat /etc/exports
# /home 192.168.1.0/24(rw,async,no_root_squash)
# /disk1 192.168.1.0/24(rw,async,no_root_squash)
/home *
/disk1 *

portmap跟nfs重新啟動過N遍

找了好久找不到答案，有人可以提示一下應該檢查哪裡嗎

兩個月前還正常的，過一陣子再看居然掛了

對了，前陣子有跳電過，兩台都重新開過機
