@scottalanmiller hi again....i guess the nfs drive is unmount from the server, because no file record on Nas after the 2016/07/28.....nothing changed on settings.....but a few server shutdown for hardware maintenance.....how can i fix it again ?
Try the mount command again. It might mount right up. If the NFS server has restarted, it would disconnect.
It is not uncommon to only have servers approved to access the storage listed. So many shops will go in and add a server one by one to enable access. If your servers almost never change, this works pretty well and is extremely secure. You can do this in the firewall too, for even more security. But if you are using DevOps and creating and destroying VMs regularly you will want to automate this in some fashion.
@DustinB3403 Thanks for your help! NFS is case sententive, it is mounted now! :D
Everything outside of the Windows and DOS worlds is case sensitive. SMB, NFS, URLs, file names, passwords, usernames, everything.
Thats what bugs me about Linux ... I hate case sensitive things.
I'm the opposite, I can't stand that DOS can't tell two characters apart and has "close enough" syntax so that people become sloppy and begin to lose the concept of congruency. I remember dealing with a bunch of students and getting them to understand things like "This", "this" and "t h I s" were not congruent was a real problem. Windows teachers users that exact doesn't mean exact, not always.
I think that is why I like cisco's ios software... i don't have to type the full command... just enough to distinguish it from the other commands available.... I see the benefits of case sensitive, it just will take me a bit to get used to using it as I learn Linux.
However, if I can get something for free instead of paying for it, I will not apologize for that.
That's what people I know who are on welfare say....
Some people who are on welfare deserve to be. Many don't but don't tear down those who have a legitimate right to it because of those who don't.
No one deserves to be on it. it's it's only an opportunity for them to get back on their feet. No one is entitled to get free money. You might say they deserve to get a better paying job so they don't need to be on it.
I can see where you're coming from, but the program is there for a purpose. The purpose may be good, but how people abuse the system is not. Again, I'm sure there are plenty of people who have taken advantage of welfare and then been successful at getting back on their feet. Like a kitchen knife, it can be used to make delicious food, or as the weapon of choice of a serial killer. The knife is just a tool. Don't fix the tool, fix how people use it.
