WebGUI crash vhen adding 9TB multipath FC

[giox069]

I'm using FreeNAS-8.2.0-BETA3-x64, connected to a Dell/EMC AX100 SAN via 2 fiber channel qlogic cards (multipath). The AX100 has a single LUN, 9TB.

It's a fresh installation of freenas, not an upgrade.

When I choose "View Multipaths" i get the error "Sorry, an error occured"

When I click on "Volume Manager" in the Web Interface, I get the following error:

I'm totally unable to initialize/use my disks :(

Here is the output from gmultipath:

Can you paste the output of:

# sysctl -b kern.geom.confxml

and

# gmultipath status

Thanks

[giox069]

Attached you will find 1561_001.xml with the output of sysctl -b kern.geom.confxml

Note that disk component names have changed from da0,da1 to da0,da2 (we reinstalled all freenas and change a fiber connection).

Here is the output of gmultipath status and gmultipath list

[root@freenas] ~# gmultipath status

          Name  Status  Components
multipath/disk1     N/A  da0
                         da2

I've committed a patch that will resolve this issue, it will be available in the next beta as well as the nightly builds. We'll keep this ticket open until you run an image with the new code.

Hello, just pinging, did you get a chance to try BETA4?

[giox069]

Installed BETA4 and the web gui no longer crashed, we now can see our LUNs.
This ticket can be closed.

We had some problems with setting up the multipath now (we see 4 for separate disks... da0 to da3), but this is no more related to this ticket.
And... unfortunately I cannot longer do testing on this hardware configuration, because the SAN and the fiber adapters have been moved to another server :(

Thank you
