MFS Client 挂载和写数据报错

kevinadmin

1. [root@Mfs-Cleint02 mfs-1.6.14]# mfsmount /mnt/mfs/ -H 192.168.0.150
   
2. mfsmaster accepted connection with parameters: read-write,restricted_ip ; root mapped to root:root

复制代码

在/var/log/messages里面显示

1. Apr  9 06:40:15 Mfs-Cleint02 mfsmount[30262]: master: tcp recv error: Interrupted system call (1)
   
2. Apr  9 06:40:15 Mfs-Cleint02 mfsmount[30262]: registered to master
   
3. Apr  9 06:40:15 Mfs-Cleint02 mfsmount[30262]: master: tcp recv error: Interrupted system call (1)
   
4. Apr  9 06:40:15 Mfs-Cleint02 mfsmount[30262]: registered to master

复制代码

使用：

1. dd if=/dev/zero of=/mfs/test.1 bs=1M count=8000

复制代码

写数据的时候

/var/log/messages里

1. [root@Mfs-Cleint02 ~]# tcpdump -i eth0 -vv |grep 192.168.0.150
   
2. tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

哪里有报错吗？

kevinadmin

加上-vv参数发现 咋用的是TCP(6) 啊？而且老有错误

kevinadmin

没有人碰到过么？

bbjmmj

两边都停掉IPV6试试，同时关掉防火墙调试。

michael1983

bbjmmj对MFS也有研究？

bbjmmj

没研究，只不过凑巧用过罢了。
