我正在使用Ubuntu Server 64bit.我已经安装了一个nfs作为rw,但每当我尝试在有问题的mountpoint上编辑任何东西时,我都会得到一个只读文件系统错误
我的etc / fstab读取：
# <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 /dev/mapper/product-root / ext4 errors=remount-ro 0 1 UUID=1cae6948-ca9d-4f0b-aec6-9e7a60bbbad8 /boot ext2 defaults 0 2 /dev/mapper/product-swap_1 none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 vnxnfs1.company.com:/NFS2 /mnt/nfs2 nfs defaults 0 0
mount返回：
/dev/mapper/product-root on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,nosuid,nodev) sysfs on /sys type sysfs (rw,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,size=10%,mode=0755) none on /run/lock type tmpfs (rw,nodev,size=5242880) none on /run/shm type tmpfs (rw,nodev) /dev/sda1 on /boot type ext2 (rw) rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw) vnxnfs1.company.com:/NFS2 on /mnt/nfs2 type nfs (rw)
cat / proc / mounts返回：

mnt上的文件读得很好,但每当我尝试更改任何内容时,我都会收到错误消息：
touch: cannot touch `/mnt/nfs2/path/to/test_file.txt': Read-only file system
我可以从其他服务器连接到有问题的nfs,并且可以正常读写.唯一的问题是在这台服务器上.我已经尝试了mount -o remount,rw vnxnfs1.company.com:/NFS2 / mnt / nfs2作为相关问题的答案,但无济于事.
对于数据转储,我只是试图包含任何可能产生线索的内容.

我一直在测试机器上的root用户遇到麻烦,写入nfs的工作原理是root用户以及其他用户(nfs-write-is-working)服务器.
