I have a query.
I have a vfiler created on a specific vlan.say vlan100. I assign an IP address to the vfiler. Now, lets consider a scenerio.
I create 3 volumes. I add the first 2 volumes to the vfiler and then exports it to the necessary host. Assuming the host is in the same vlan , the host is able to mount the 2 volumes.
Now, coming back to the 3rd volume, I leave out the 3rd volume in vfiler0 and export it to the same host (the host is in vlan101). Will the host be able to see the 3rd volume exported from vfiler0?
Thanks in advance.
Just to be clear, if you want to mount an export from vfiler0 you have to use vfiler0s' IP, and if you want to mount an export from vfilerx you should use vfilerxs' IP, right? It doesn't matter if vfiler0 and vfilerx IPs are on the same VLAN as long as the IPs are different.
If you have the same directory exported on vfiler0 and vfilerx you can mount it with both vfilers' IPs.
Thanks for the response.
Just wanted to be specific on my query. My vfilerx's IP is in virtual interface( vif-100)
My host's IP is in the same vlan(vlan 100) range.
1> My host is able to mount the resources from vfilerx
2> Will the same host be able to mount the 3rd volume(which is outside vfilerx) on vfiler0 ?
In a nutshell, my query is, If the vif interface (vif-100) is a configuration from both physical filer side and vfiler side as well, where a resource if exported from the physcal filer can be mounted on the host?
Yes. You can mount vfiler0:/vol/volname and vfilerx:/vol/volname ... the targets are different IPs. vFiler0 is fully functional as are additional vFilers created. Most customers put all data in vFilers if they use vFilers, but still mount the root volume in vFiler0 for example.
It can be confusing... especially with the default options nfs.export.auto-update on setting... vfiler0 will create an export for every volume even if owned by a vfiler. When owned by a vFiler, vfiler0 can't take mounts to the volume since the vfiler handles the mounts. So your exports file may have entries that aren't used. Most new vfiler users also have to remember that each vfiler has its own root volume so you modify exports in the vfiler root/etc.
Thats right Scott,
Lets say my nfs.export.auto-update is set to off. In that case will the volume exported from vfiler0 to a host be mountable from the host? Considering the host has the IP from vlan 100 only? from storage, I add another IP to vif-100 as an alias. The host would try to mount the volume with the alias IP as the target IP.
