## 缺陷信息

【问题复现步骤】
问题1：
服务端：
mkfs.ext4 -F /dev/sdb
mount /dev/sdb /mnt/sdb
echo "/mnt *(rw,no_root_squash,fsid=0)" > /etc/exports
echo "/mnt/sdb *(rw,no_root_squash,fsid=1)" >> /etc/exports
systemctl restart nfs-server
两个客户端：
mount -t nfs -o rw,vers=3 192.168.240.251:/mnt/sdb /mnt/sdbb
就绪后按如下顺序在两个客户端上操作：
    客户端1 客户端2
ls -l /mnt/sdbb/afile
                                echo hello there > /mnt/sdbb/afile
echo HELLO > /mnt/sdbb/afile
cat /mnt/sdbb/afile

问题2：
mkfs.ext4 -F /dev/sdb
mount /dev/sdb /mnt/sdb
echo "/mnt *(rw,no_root_squash,fsid=0)" > /etc/exports
echo "/mnt/sdb *(rw,no_root_squash,fsid=1)" >> /etc/exports
systemctl restart nfs-server

mount -t nfs -o rw,vers=3 192.168.240.251:/mnt/sdb /mnt/sdbb

问题3：
mkfs.ext4 -F /dev/sdb
mount /dev/sdb /mnt/sdb
echo "/mnt *(rw,no_root_squash,fsid=0)" > /etc/exports
echo "/mnt/sdb *(rw,no_root_squash,fsid=1)" >> /etc/exports
systemctl restart nfs-server

mount -t nfs -o rw,vers=3 192.168.240.251:/mnt/sdb /mnt/sdbb

问题3：
先上报OPEN，再上报CREATE
终端1：
[root@localhost test]# ./open
成功打开/创建文件: /mnt/sdbb/testfile
[root@localhost test]#
终端2：
[root@localhost test]# ./inotify /mnt/sdbb

testfile --- IN_OPEN

testfile --- IN_CREATE
[root@localhost test]#

【期望结果】
问题1：
客户端1读取到的文件内容与写入的一致
