nfs硬盘共享问题

boywhocools

我这有一套服务器＋客户端配置，共三台dell690机器，通过交换机连接，一台设为服务器，服务器上安装数据库和4块公共scsi盘，另两台为客户端，客户端使用服务器的数据库和一块共享硬盘的数据，服务器端使用nfs共享数据盘给客户端使用，系统为redhat ws3u6（跟as3u6类似），这套系统稳定使用1年多了。
现在nfs出问题了，使用中会频繁掉线，开机正常，使用中途就断掉，一直找不到原因，请大虾帮忙给个意见。。。谢谢！

日志应该有提示的信息

需要看哪个日志文件？ 没看过。。。
是/var/log/messages 吗？

日志当然是越多越好，越全越好。

最好是nfs的日志。你rpm -ql samba 看一下装到 /var目录下装了哪些文件？都搞出来让大家看看吧。

linux系统下的nfs还是很强壮的，现在很多大的集群系统都是通过nfs共享来用的。

中间出现/var下文件不能打开会不会有问题？
这是服务器上的日志
