Export path problem

[juno2]

I edit the file /etc/exports and add the line /tmp/ 168.1.1.2(rw) , then run "exportfs -a" , but it pop the below messages , could suggest what is wrong on my system ? thx
_______________
exportfs: No 'sync' or 'async' option specified for export "168.1.1.2:/tmp".
Assuming default behaviour ('sync').
NOTE: this default has changed from previous versions

Take out the trailing slash

change /tmp/
to /tmp

Then you should be fine.

This isn't showing any errors. This is just stating that the method of accessing the disk wasn't listed, and that it is going to synchronously do any IO for the disk.

If you read 'man 8 mount', it states the two options, sync and async are just the opposite sides of the coin.

'exportfs' now assumes you want sync instead of async.

To get this message not to come up when you run 'exportfs -a', use an entry like:

/tmp/ 168.1.1.2(rw,sync)

in your /etc/exports file instead.

Hello!

It's not error it's just a worning.
As you see now the default is changed,
and the better for the feature also is do
like i do always write the default parameters because in some day it may be not the default.
Also you think you work with async but you get by default sync because in the past this was a default.
