Hi Marty,

Thanks for the fast reply!

Thanks, what setup do you have in the cloudstack interface? Can youprovide
a screenshot of the secondary storage page (under Infrastructure)?


I attached the screenshot.

Could you also try the following on another host (not the managementor
SSVM):
sudo -i
mkdir mounttest
sudo mount 10.244.18.55:/secondary mounttest
Can you write into the directory mounttest and see the files?

I tried mount from another host(10.244.18.122), it failed. Thefollowing is the output:

This host can ping the nfs server.

Hi Marty,

Here is the information:

[root@meng]#cat /etc/exports
/secondary *(rw,async,no_root_squash)
/primary   *(rw,async,no_root_squash)

[root@meng Downloads]# exportfs
/secondary      <world>
/primary        <world>

[root@meng Downloads]# exportfs -a

There is no output for exportfs -a.

Hi Meng,

I would first look at the management server and ignore the SSVMuntil you

are sure the NFS share is working.

Could you post the output of: exportfs -a and cat /etc/exports ?
I can then give more guidance.

Thanks,
Marty

The NFS server address listed above is actually the address ofssvm.

Could

someone tell me why the ssvm address is there instead of the nfsserver?

am using the management server as the nfs server, its ip is10.244.18.55
