Mounted nfs on /var FS?

[Sudhaadm]

Hi All,
We have mounted ServerA Normal(Lke /application) Filesystem on ServerB /var Filesystem. will it create any problem?

thanks

It depends have you mounted it as /var or as something like /var/ServerA. The former is bad; the latter is ok.

The mount process in HP-UX essentially inserts a filesystem onto a specific directory in the local system, so if you mounted servera:/application onto your local system at /var/application, there are no issues. Now the mount command needs an empty directory but it is not checked (except that nothing is open on the mountpoint or any subdirectories). That means that if a directory like /var/application has files (and perhaps diretories), mounting on top of the same directory will 'hide' the old directory structure. That is why you can't mount something on /var -- all the files and directories would be hidden. But you can create a directory called /var/application and mount to that directory just fine.

One thing that comes to mind is the use of /var/tmp for some system related functions and slow response from an nfs server crippling the functionality. If you have a robust network between serverA and serverB and your NFS access rights are set up properly (I would check into root access rights especially) you may be okay. But I have to warn you, it is not a wise idea in my opinion and definitely not common practice.

Yes,,,great Analyzation ..
Thanks for the answers for my query..
Is it harmful to mount in /var filesystem?
Mount serverA:/Application /var

[A. Clay Stephenson]

Okay. That example is bad; don't do it.

hi clay,
its bad...but is there any high impact ?

[A. Clay Stephenson · Accepted solution]

Only if you consider little things like crashes "high impact". Your system will be missing things like /var/tmp. Your lp spooler and mail will instantly be dead although probably not as quickly as the system itself crashes. Simply create a direcory under /var (e.g. /var/application) and use that as the mountpoint.
