SuSE linux NFS掛載失敗案例處理:mount.nfs: access denied

1. 環境描述
NFS server和NFS client作業系統版本:
bidw2:~ # cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 1
bidw2:~ # uname -a
Linux bidw2 2.6.32.59-0.7-default #1 SMP 2012-07-13 15:50:56 +0200 x86_64 x86_64 x86_64 GNU/Linux
2. NFS client掛載時出現錯誤
bidw2:~ # mount -t nfs -o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0 192.168.142.60:/filedir /filedir mount.nfs: access denied by server while mounting 192.168.142.60:/filedir
經確認過,防火牆都是關閉的,網路是正常的:
bidw2:~ # showmount -e 192.168.142.60
Export list for 192.168.142.60:
/filedir 192.168.142.*
在NFS server的messages日誌中有這樣的提示:
Sep 24 12:57:37 bidw1 mountd[17400]: refused unmount request from 192.168.142.61 for /filedir (/filedir): unmatched host Sep 24 12:57:55 bidw1 mountd[17400]: refused mount request from 192.168.142.61 for /filedir (/filedir): unmatched host
NFS server的/etc/exports配置如下:
bidw1:~ # cat /etc/exports
/filedir 192.168.142.*(rw,no_root_squash,sync)
這種配置,我在SuSE 10 sp1/sp2的系統中都做過配置,NFS都是可以正常使用的,也可以正常掛載,為什麼到了SuSE 11後就不行了呢?
3. 解決辦法
根據以往碰到這類問題的經驗,我將NFS server的配置調整為:
bidw1:~ # cat /etc/exports
/filedir 192.168.142.0/24(rw,no_root_squash,sync)
然後重啟了下NFS server:
bidw1:~ # rcnfsserver restart
再次在NFS client中進行掛載NFS時,發現掛載成功了:
bidw2:~ # mount -t nfs -o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0 192.168.142.60:/filedir /filedir
bidw2:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 127G 43G 78G 36% /
devtmpfs 109G 5.0M 109G 1% /dev
tmpfs 64G 26G 38G 42% /dev/shm
/dev/sda3 30G 309M 28G 2% /home
/dev/sda2 50G 498M 47G 2% /opt
/dev/sda6 50G 18G 30G 37% /opt/oracle
192.168.142.60:/filedir
1.5T 316G 1.1T 23% /filedir
總結:
或許在SuSE 11系統中,已經不能使用通匹符*做匹配了,只能做精確匹配,或時使用192.168.142.0/24做網段匹配。
