nfs
[root@nfsclient alidata]# touch 24 touch: cannot touch `24‘: Read-only file system
一、查看mount 是否有權限
[root@nfsclient /]# mount /dev/sda3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0") /dev/sda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) 10.10.10.11:/sharedata on /alidata type nfs (rw,vers=4,addr=10.10.10.11,clientaddr=10.10.10.12) [root@nfsclient /]# ll total 106 drwxr-xr-x. 2 nfsnobody nfsnobody 4096 Oct 18 22:51 alidata dr-xr-xr-x. 2 root root 4096 Oct 18 21:32 bin dr-xr-xr-x. 5 root root 1024 Jul 14 21:44 boot drwxr-xr-x. 2 root root 4096 Nov 23 2013 cgroup
二|、嘗試賦予777權限
[root@nfsclient /]# chmod 777 /alidata/ chmod: changing permissions of `/alidata/‘: Read-only file system
三、重啟nfs
[root@nfsser /]# /etc/init.d/nfs restart
Shutting down NFS daemon: [ OK ]
Shutting down NFS mountd: [ OK ]
Shutting down NFS quotas: [ OK ]
Shutting down NFS services: [ OK ]
Shutting down RPC idmapd: [ OK ]
Starting NFS services: exportfs: No options for /sdata 10.10.10.0/24: suggest 10.10.10.0/24(sync) to avoid warning
exportfs: No host name given with /sdata (rw,sync), suggest *(rw,sync) to avoid warning
[ OK ]
Starting NFS quotas: [ OK ]
Starting NFS mountd: [ OK ]
Starting NFS daemon: [ OK ]
Starting RPC idmapd: [ OK ]註：提示在24和（ 之間有空格；終於找到原因
[root@nfsser /]# cat /etc/exports ##share data for 20171018 /sharedata 10.10.10.0/24 (rw,sync)
然後編輯，刪除空格，重新啟動nfs
[root@nfsser /]# /etc/init.d/nfs restart Shutting down NFS daemon: [ OK ] Shutting down NFS mountd: [ OK ] Shutting down NFS quotas: [ OK ] Shutting down NFS services: [ OK ] Shutting down RPC idmapd: [ OK ] Starting NFS services: [ OK ] Starting NFS quotas: [ OK ] Starting NFS mountd: [ OK ] Starting NFS daemon: [ OK ] Starting RPC idmapd: [ OK ]
檢查出什麽問題，然後在重新建立文件
[root@nfsclient alidata]# touch asd [root@nfsclient alidata]# ll total 72 -rw-r--r--. 1 root root 0 Oct 18 23:53 ad -rw-r--r--. 1 nfsnobody nfsnobody 0 Oct 19 00:11 asd -rw-r--r--. 1 nfsnobody nfsnobody 46850 Mar 23 2016 log.txt -rw-r--r--. 1 nfsnobody nfsnobody 14476 Mar 23 2016 mytlv-20160119.log -rw-r--r--. 1 nfsnobody nfsnobody 4537 Sep 5 22:12 qzj.txt
終於解決，原因是因為自己在配置/etc/exports的時候沒有註意，中間添加了空格，
