请教：aix Nfs 问题

tipsluo

两台 S70 (假定为 A 机和 B 机)，A 机(10.1.1.1)上 /nfs1 通过 NFS 映射到 B 机 /nfs1, B 机在使用完 A 机数据后忘记去掉 NFS。现在 A 机已不存在，B 机用原来 A 机的 IP 工作，在 B 机上就出现了下面问题：\r\n\r\ns70b# df -k\r\nFilesystem    1024-blocks      Free %Used    Iused %Iused Mounted on\r\n/dev/hd4            65536     31444   53%     2086     7% /\r\n/dev/hd2          1409024    362504   75%    41258    12% /usr\r\n/dev/hd9var         65536     54456   17%      574     4% /var\r\n/dev/hd3            65536     57068   13%      263     2% /tmp\r\n/dev/hd1            16384     15460    6%       58     2% /home\r\nNFS server s70a not responding still trying\r\n^Cs70b# \r\n\r\n本来下面还有其它文件系统，却不能继续显示出来，好象是因为找不到 s70a:/nfs1。我试图去掉 B 机上的 NFS，不论是 rmnfsmnt, 或 umount, 都失败。请问应怎么办？\r\n\r\n\r\n

I mount a NFS dir on AIX(client), server is a Solaris. Then I stop the nfs server. On AIX, \"df -k\" says \"\":\"NFS server 9.181.24.47 not responding still trying\".  I issued umount, result is \"Warning: umount:: RPC: 1832-019 Program not registered\", but \"df -k\" can work properly again. So it seems umount works.

umount -f\r\n\r\n-f Forces an unmount in a remote environment. Use to free a client when the server is down and server path names cannot be resolved. The -f flag is not supported for journaled file systems. \r\nNote: This forced unmount works only when there is no hold on the directory, that is, when the directory is not some user\'s working directory and there is no process started and still running there.

I can not umount it. System report error when I issued the umount command as following:\r\n\r\ns70b# umount /nfs1\r\numount:1831-015 16 error while unmounting 10.1.1.1:/nfs1 \r\n-The requested resource is busy;\r\n\r\nI think the cause may be the same ip address (10.1.1.1) which is used by both the original server (host a) and the present server (host b). When NFS on s70b try to find the resource on s70a with the ip address 10.1.1.1,\r\nit can find a host with this address. But this host is s70b itself, not s70a. So NFS reports wrong. How can I do?

The same error reported as the command \"umount /nfs1\" when I issued \"umount -f /nfs1\".

Thank you, chenpager. But I should make the df command normally.

fuser -u /nfs1，有什么进程还在用它吗？
