Hmmm. I've checked 
ftp://download.nvidia.com/XFree86/Linux-x86_64/304.60/README/xconfigoptions.html,
 
but not really found anything that seems to be related to this. Also, 
the problem is not really making the monitor the primary, but rather to 
make sure it stays enabled. In a sense, it is a "disabled primary" once 
I log in.

That would be an issue related to the "EDID" monitor info, I suppose. 
But in my case, the monitor is recognised just fine, it's just that it's 
switched off in the driver's internal config. Or that's what it looks 
like, anyway.

does it happen with a different user account?
since it happens on login it might be something in ~/.nvidia-settings-rc ?

Good question. I was quite convinced that it did, but I can't have 
tested properly, because when I log into another account now, I find 
that everything is OK. That's a bit embarrassing...

> since it happens on login it might be something in ~/.nvidia-settings-rc ?
It's not ~/.nvidia-settings-rc, though, as I get this problem even after 
copying the file from a different user (without this problem) or when 
just removing it (and other accounts work just fine without one.) Weird...

 I don't have your problem, but another one.

 I want my second monitor to be above the internal monitor by default.

 I solved that by adding

Option "TwinViewOrientation" "Above"

 to the Device section of the xorg.conf file.

 Maybe you can google "xorg.conf twinview" and find the option to
 insert into xorg.conf that makes your external monitor the primary?

Found it! It turns out that it's actually the GNOME desktop resolution 
handling that's doing this, i.e. the setting stored in 
/desktop/gnome/screen/default/0 under "gconf". The problem went away 
after I simply opened Preferences->Screen Resolution, and confirmed the 
current setting of 3600x1200 by pressing Apply - after re-enabling the 
screen. Not sure what the "stored" setting originally was. I'm quite 
sure I haven't touched it in a long time, though, so *something* related 
to its handling must have changed after an upgrade. Also, all entries 
but 3600x1200 (which is the max total display area with both screens) in 
the config tool correspond to pixel counts that may be displayed on the 
laptop screen, and selecting any of them will disable the external monitor.

[CentOS] Raid 5 Q

2012-11-16 Thread Phil Savoie
I have a raid 5 built on an opensuse box that I just reinstalled Centos 
6.3 on.  Is it possible to rebuild the raid 5 array non-destructively?

I have googled on this and have found using mdadm --scan --assemble 
.  Will this do it?  I sure wouldn't want to lose my 
data on the array if possible.

thank you,

Phil

It could be possible, but I think I would rather try to back it up with some
sort of recovery system first... If the data is VERY critical, I would clone
the drives with DD first just to make sure...

Thank you for your reply.  What I did ewas the following:

mdadm --detail --scan > /etc/mdadm.conf

and thhis thankfully recreated /dev/md0 and was able to add the entry 
into the fstab mount the device and see all my data as I left it.

Big whew!!

That's another way to do it - because that should overide 
the setting in the php.ini file.

Seen this before on openSUSE. If you put a disc in the drive, the errors stop

[CentOS] iSCSI Question

2012-11-16 Thread Steven Crothers
Hey everyone,

Is anybody aware of a /true/ active/active multi-head and multi-target
clustered iSCSI daemon?

IE:

Server 1:
Hostname: host1.test.com
IP Address: 10.0.0.1

Server 2:
Hostname: host2.test.com
IP Address: 10.0.0.2

Then they would utilize a CLVM disk between them, let's call that VG "disk"
and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and
so on.

That would essentially make both host1 and host2 identical iSCSI targets.
So I could hook up 30 servers to each LUN on each host1 and host2 (assuming
those block devices had a cluster aware filesystem on them).

However, what I wan't to accomplish is true active/active MPIO utilizing
the dm driver to combine LUN 1 from both host1 and host2 as a single
/dev/dm-0 device in active/active mode.

This would allow me to multipath across multiple fabrics, develop true high
availability and increase my throughput significantly.

Any idea of an iscsi tgtd that supports this? As far as I can tell, none do
(that I can find). I know some proprietary vendors have this type of
functionality, which may or may not be using iSCSI code (but that's a whole
set of arguments for later..).

Ultimately, my goal is this.

I want to take my existing Ceph cluster, expose a handful of RBDs from it
to two iSCSI heads running C6 or RHEL6 or what have you, so I can use my
inexpensive storage built on Linux -- for my Windows 2008 machines.

Thoughts?

There's a reason that those proprietary vendors are able to charge big
$$$ for this functionality.
