Multistore and VIFs

[nsitps1976]

Is it possible to aggregate all Ethernet interfaces on a controller into a static multimode VIF and have this VIF be partitioned across multiple vFilers?

I thought I read somewhere that you could only assign physical interfaces to vFilers? – I want all vFilers to be able to utilise the entire aggregate bandwidth of a VIF which includes 4 Ethernet interfaces, I do not want to limit each vFiler to one Ethernet interface.

Correct. With 7.x you will need a 4th vlan since you can't assign an ip to the base vif when you create vlans in that vif. When you upgrade to 8.x you probably would keep the same config (why have a more disruptive change)..but will then be able to assign an ip to the base vif.

Thanks

Are there any guidelines on what the size of the vfiler /etc volume should be? - Can't find any info on this.

[scottgelb]

It can be as small as 20MB.. The min vol size.. But I usually size at 10GB..

Most things long to vfiler0.. However if you mirror to/from a vfiler directly or enable cifs auditing, then /etc will grow in the vfiler.. So size monitor it.. If all mirror/vault is from vfiler0 it won't log to the vfiler.

10GB isn't a lot and works almost every time..

Excellent, thanks.. Another question if you don't mind (this is going to be a long thread, hopefully it will help others though) - If I leave a vlan in the default-ipspace and then assign an ip to this vlan can I then access vfiler0 on this vlan? - I am sure this is correct but want to be sure.

[scottgelb]

The vlan in the default ipspace can be used for vfiler0 as long as that ip is not bound/assigned to a vfiler. We can use ip aliases to assign additional ips so that vfilers in the default ipspace and and vfiler0 can share the vlan interface, but with different ip addresses.

Hi Scott

I am having some issues adding an alias to an interface which is already assigned to a vfiler.

If I try:

ifconfig if-name alias 10.176.131.12 netmask 255.255.255.0

I get:

ifconfig: can't assign address to if-name, no vfiler in this interface's ipspace (ips-131) has this address

And if I try:

vfiler run vfilersp setup -e if-name:10.176.131.12:255.255.255.0

I get:

Can't bind IP address 10.176.131.12. Either this IP address belongs to other vfiler or it is not configured to vfiler: vfilersp

[scottgelb]

Ifconfig and setup -e will do the same binding.. But I don't like setup since it whacks several etc files (saves to bak) but still needs fixing after.. Exports, resolv.conf nsswitch.conf, hosts.equiv, etc..

What I think has happened is you don't have the ip added to the vfiler yet. "vfiler add vfilername -i 10.176.131.12" then do the ifconfig.. It has to be added to thje vfiler first.. You will see the ip "unconfigured" in vfiler status -a then the ifconfig (or setup -e which isn't a good alternative) will bind it to the vfiler and it will show configured.

Using your guides I have tried to avoid the setup command, this was my last resort prior to asking you.

I did assign the ip to the vlan interface during vfiler creation,, I can also see this using vfiler status -a

[scottgelb]

Is it configured? Is the vfiler in the same ipspace as that interface? It has to be something simple..

It is listed with the name of the interface at the end, it does not mention configured or unconfigured.

The interface is in the same ip space as the vfiler and the ip address was assigned to the interface during vfiler creation.

I can email you the exact output?

[scottgelb]

Sure.. I can look later..

ifconfig -a

vfiler status -a vfilername

ipspace list

You can also try vfiler remove and vfiler add to try to reset.. If it doesn't show unconfigured it might be working.

is "vfiler add vfilername -i x.x.x.x" the same as an alias? - if I use this command then the new IP is listed as unconfigured????

[scottgelb]

Yes.. Vfiler add -i for any ip no matter what is bound to later.. Can be a vif, a vlan, an alias, or to an interface (e0a).. Then ifconfig after to configure and it binds automatically.

Hi Scott

I have introduced a 2nd vlan / subnet into an ipspace - I have a default route for the ipspace which corresponds to the1st vlan, can I add a default route for the 2nd vlan??? If not what are my options??

Thanks

[scottgelb]

There can only be 1 default route per ipspace/routing table..but add a network (or host..but more likely network) route.. Both manually and to vfiler0's /etc/rc with "vfiler run vfilername route add net x.x.x.x x.x.x.x 1"

I wanted the 2nd subnet to be able to route out of the vlan, however thinking about it again I don't need this as I can snapmirror / mgmt access into the vfiler on the 1st vlan.

thanks for the quick response

Should I be able to create SAN datastores with VSC 2.1 connected to a vfiler?

Surely not as the volume has to be created within vfiler0 and then assigned to vfilerX?

Anyway, I gave it a go but receive the error "No datastore types are available".

[scottgelb]

For iSCSI you should be able to directly provision to a vfiler with vsc.  NFS does require vfiler0 permissions to add nfs datastores to a vfiler with vsc.   Roger did a really nice preso on this with screen shots...I don't see a place to upload a file here but will try to find it...used to be here before the upgrade to communities.

[nsitps1976]

Ok, thanks.

I did try the "vol create" command within the vvfiler context, howerver, the create command was not listed?? This is why I thought vsc would not be able to provision datastores. This is an iscsi environment.

[scottgelb]

You can't create a volume in a vfiler...vfiler0 only task.. but VSC authenticates to both vfiler0 and the vfiler.
