SuSE linux NFS挂载失败案例处理:mount.nfs: access denied

1. 环境描述

NFS server和NFS client操作系统版本:

bidw2:~ # cat /etc/SuSE-release SUSE Linux Enterprise Server 11 (x86_64)VERSION = 11PATCHLEVEL = 1
bidw2:~ # uname -aLinux 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挂载时出现错误

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 /filedirmount.nfs: access denied by server while mounting 192.168.142.60:/filedir

经确认过,防火墙都是关闭的,网络是正常的:

bidw2:~ # showmount -e 192.168.142.60Export list for 192.168.142.60:/filedir 192.168.142.*


在NFS server的messages日志中有这样的提示:

Sep 24 12:57:37 bidw1 mountd[17400]: refused unmount request from 192.168.142.61 for /filedir (/filedir): unmatched hostSep 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)

这种配置,我在SuSE 10 sp1/sp2的系统中都做过配置,NFS都是可以正常使用的,也可以正常挂载,为什么到了SuSE 11后就不行了呢?


3. 解决办法

根据以往碰到这类问题的经验,我将NFS server的配置调整为:

bidw1:~ # cat /etc/exports /filedir 192.168.142.0/24(rw,no_root_squash,sync)

然后重启了下NFS server:

bidw1:~ # rcnfsserver restart

再次在NFS client中进行挂载NFS时,发现挂载成功了:

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 /filedirbidw2:~ # df -hFilesystem            Size  Used Avail Use% Mounted on/dev/sda1             127G   43G   78G  36% /devtmpfs              109G  5.0M  109G   1% /devtmpfs                  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/oracle192.168.142.60:/filedir                      1.5T  316G  1.1T  23% /filedir

总结:

或许在SuSE 11系统中,已经不能使用通匹符*做匹配了,只能做精确匹配,或时使用192.168.142.0/24做网段匹配。
