Multistore failover

I'm trying to wrap my head around vfiler configs in HA pairs. I've fount bits and pieces in various docs but haven't found a comprehensive guide.

Exactly how does a vfiler failover between nodes? What do I need to make this work? Could someone provide example rc files?

Here is where I'm at:

FilerA has several vlans on vif0: 101, 102 103 104

FilerB has the same vlans defined

FilerA has several vfilers with ipspaces:

vfA1, ipspace ip-vfA1 vif0-101 10.0.0.1/24

vfA2, ipspace ip-vfA2 vif0-102 10.0.2.1/24

FilerB has several vfilers with ipspaces:

vfB1, ipspace ip-vfB1 vif0-103 10.0.0.1/8

vfB2, ipspace ip-vfB2 vif0-104 10.0.3.1/24

All ipspaces on both filers with same interfaces

The ifconfig lines in the rc files specify the partner interfaces, e.g.

on FilerA.:ifconfig vif0-102 10.0.2.1 netmask 255.255.255.0 partner vif0-102

on FilerB: ifconfig vif0-102 10.0.2.4 netmask 255.255.255.0 partner vif0-102

The owning filer's rc file has the default route for each vfiler specified with a vfiler run and a default route for default-ipspace.

When I failover, the interfaces don't work on the vfilers. I see this on the console of the takeover filer:

Mon Apr  4 17:35:38 GMT [FilerB: net.ifconfig.noPartner:error]: ifconfig: 'vif0-102' cannot be configured: Address does not match any partner interface.

Does the partner need an ip assigned to it's interface (on the same subnet as the primary)? I tried this but it didn't work:

FilerB> ifconfig vif0-102 10.0.2.4 netmask 255.255.255..0
ifconfig: can't assign address to vif0-102, no vfiler in this interface's ipspace (ip-vfA2) has this address

So it looks like the rc file ifconfigs won't work the way I have them on the partners.

If I try to configure a shared interface in System Manager on the partner, it insists on an ip but fails because there is no vfiler on the partner in that ipspace. Everything in the default-ipspace works fine.

That should work.. Test a failover.

For a partner only interface no host entry needed. Can you email me full rc and hosts from both nodes? And ifconfig -a, vFiler status -a and Ipspace list

Scott,

How can I email it to you directly?

I performed a takeover again from the other filer,

then I check the status of the vfiler.

vfiler1 running

ipspace: zylab_ipspace

IP address: 192.168.45.130

it is saying unconfigured.

If the interface is unconfigured I would check the messages file for what happened on the ifconfig and where it failed.

Scott,

I think what happened is, I should have run

ifconfig NET1-345 partner NET-345

on the partner filer. I put it in RC but I did not run it. See below it does not show the partner.

NET1-345: flags=0x230c862<BROADCAST,RUNNING,MULTICAST,TCPCKSUM> mtu 1500

ether 02:a0:98:1a:84:7e (Enabled interface groups)

That is it. No partner configured on it.

Scott,

I finally got it to work. It looks like it wanted me to first failover the partner filer to the primary (vfiler owner) filer. Then I perform a giveback. then this time I let the partner filer takeover the primary filer. This time it worked. I guess it has something to do with the rc on the filer not reloaded yet? What do you think?

What is the command to reload the RC? so that I won’t have to perform a takeover/giveback just to refresh reload the rc

you can run source /etc/rc to source the file and run all the commands...but in this case when you have been troubleshooting the takeover/giveback is what I would do.

Here is my vlan create statements

vlan create NET1 350 348

vlan create NET1 345

345 is for the vfiler. Is that a problem that I have two separate vlan create statement?
