Gareth Hastings's questions

Does anyone know if this SAN when configured to run on Fabric A of a Dell M1000e should be able to work on either A1 or A2?

I have one configured along with Force 10 - MXL 10/40 switches in Fabric A. These switches are not configured as a stack but as two separate switches.

During testing if I shutdown the port the SAN is connected to on A1 it just becomes unreachable. It doesn't fail over to A2 at all.

If I fail over the SAN controller it still doesn't use A2.

The switch shows the port as up but it has no MAC addresses registered with it.

I have looked through lots of the product documentation but this information is not clearly explained in any of them.

Dell support were also unable to answer my question and said that as we didn't configure the switches in their recommended fashion (stacked) they couldn't help us.

I've recently setup NGINX and had to implement various redirects to manage pages from our older websites that were still returning hits in Google (and other various linked pages).

Some of these links we have to redirect to explicit locations but the rest should just be redirected to the root directory /.

I have been asked to redirect any 404, 500 and 501 pages back to the root directory. I thought this would be fairly easy to achieve using the error_page directive. My server block contains the following

error_page 404 500 501 = @redir;

location @redir
{
    rewrite .* / redirect;
}

In my log files I see the following when I request random non existant files

x.x.x.x - - [02/Mar/2012:11:25:42 +0000] "GET /fgfg.jpg HTTP/1.1" 500 799 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.46 Safari/535.11"

This now brings up two questions:

1. Why is this returning a 500 error rather than a 404?
2. Why isn't the 500 redirecting as that's being handled by the error_page section??

Here is the whole server block

server
{
    listen       x.x.x.x:80;
    server_name  www.blah.com;

    access_log  /var/www/www.blah.com/log/access.log;
    error_log   /var/www/www.blah.com/log/error.log;

    root /var/www/www.blah.com/public;
    passenger_enabled on;

    error_page 404 500 501 = @redir;

    location @redir
    {
        rewrite .* / redirect;
    }

    location ~* "/Managed Services"
    {
        rewrite .* /managed_services permanent;
    }

    location ~* /solutions_arch.asp
    {
        rewrite .* /arch permanent;
    }

    location ~* .*\.(php|asp)$
    {
        rewrite .* / permanent;
    }
}

Any ideas?

I have a strange issue that appears to have started recently.

When I copy a large file (Approx 6GB) from my laptop to one of our older fileservers the server runs out of memory after a few seconds.

This has only started recently, maybe since patch Tuesday although I can't be sure.

This server is a Windows 2000 sp4 machine, its a Dell 2950 with 1GB ram (Note: I am sure this server had more than 1GB!, I can't physically check until the end of the day when I can power it down), 3GHz Xeon proc, 4 x 250Gb 7.5k RPM SATA drives in raid 10 and a 1 Gigabit NIC connected to a 1GB port on an intel managed switch.

(Apparently I can't post images so a link will have to do)

As soon as I stop the copy the memory instantly frees up:

I've removed the antivirus which made had no impact. I've changed the "File and Print Sharing for Microsoft Networks" options to balanced.

We have another server, Windows 2000 SP4 with 2GB Ram, 2.8Ghz Intel Quad Core, 6 x 300Gb 15k SAS in raid 10.

When I copy the same 6GB file here the amount of available memory doesn't change.

Is there anything else I can look at while the server is running? As it's in use and not really affected by small file copies I can't reboot it just yet.

Here is a screen shot of some perfmon counters I had open just as the server runs out of memory.
