GNOME System Monitory says no mem consumed by ZFS??

Hi, I'm guessing there is probably a simple answer to this but Google and I haven't found it.
With OpenSolaris svn_111b, the GNOME System Monitor would show almost all memory consumed. (By ZFS cache...a good thing.)
With Solaris Express svn_151a, System Monitor shows <1gb (out of 16gb) consumed.
Would I be correct in assuming that ZFS cache is no longer counted in the System Monitor, but ZFS is still using almost all available memory (hopefully)?
The reason for concern is that with svn_111b, I was getting a reliable 90 MB/s transfer over SMB (with Solaris as Samba server), without even jumbo frames. But now, on the same server and network config but with a clean install of svn_151a and minimal tweaking, I'm getting terrible performance at about 3 to 10 MB/s.
(I've posted the performance problem specifically as a separate post, so as not to double-post I don't want to dwell on that here - this is just about the System Monitor / ZFS cache question.)
Thanks!!

Type of data and access:
- Mostly large media files (DNG photos, large photoshop project files, high bitrate 1080p video, 32-bit/96khz audio, etc.)
- Plenty of small "office" data files too, but of secondary importance.
- Low usage. Typically accessed by one CIFS/SMB client - and one application - at a time. Needs throughput, not IOPS.

[Solved]gnome-system-tools You are not allowed access to sys config

I did a FTP install of i686 Arch Linux on a friend's machine. I could not get gnome-system-tools to work, keep getting:
The configuration could not be loaded
You are not allowed access to the system configuration
So, I tried gnome-system-tools on an i686 Arch install on my machine, and gnome-system-tools worked. Then I did a pacman -Syu and fully updated the system. The updates included udev which now prints how long udev events took on boot up. After the updates, gnome-system-tools no longer works. Same symptoms as the new install.
Both machines have stbd in the /etc/rc.conf DAEMONS line. Both the user and root in both machines are part of the stb-admin group. Using gksu or launching as root in a terminal window results in the same problem. The problem seems to be in system-tools-backends which works in conjuntion with dbus as I get this error:
(time-admin:7607): Liboobs-WARNING **: There was an unknown error communicating with the backends:
Process /usr/share/system-tools-backends-2.0/scripts/SystemToolsBackends.pl exited with status 127
gnome-system-tools and system-tools-backends are part of the community group, so as far as I know, writing a bug report is out. Both gnome-system-tools and system-tools-backends are out of date in community. system-tools-backends is version 2.4.1 and the current version is 2.6.0. I tried using makepkg to compile the new 2.6.0 version of system-tools-backends but it fails saying it needs dbus >= 1.1.2 but version of dbus is 1.0.2. So it appears that dbus is out of date also. That is a far as I got.
I know this has been a problem in the past, but I got it working until this latest update.
Anyone got any ideas on this?

When I went to rebuild system-tools-backends, I had decided I needed to try and build the latest version of it, which didn't work as stated above. By this time the lateness of the hour, and the current frustration level caused me to quit for the night and write this thread. I am fairly sure I did NOT rebuild the current system-tools-backends.
Anyway, deleting gnome-system-tools and system-tools-backends, then rebuilding the current version of both gnome-system-tools and system-tools-backends fixed the problem. Be sure to follow the post installation comments from system-tools-backends.
I wrote a bug report in the AUR.

I've had the same problem with my users-admin and users-time... I've tried all the fixes from most of these posts... except for that string of code that someone wrote in this post: http://bbs.archlinux.org/viewtopic.php?id=42910
for file in `pacman -Ql gnome-system-tools | grep desktop | cut -d" " -f2`; do cat $file | sudo sed 's/$^Exec=$$.*-admin$/\1gksudo \2/g' | sudo tee temp.desktop.tmp; sudo mv temp.desktop.tmp $file; done
I wasn't sure what this string actually would do, so I haven't tried it yet. I figured there would be an easier way of fixing this problem. Like a simple edit in the SystemToolsBackends.pl file.....
any help would be cool.

Hi dip_kinu,
I apologize, I'm a bit unclear on exactly what device you are trying to set up and what is happening when you try to do so. If you are having issues remembering your Apple ID, or feel like you may have set up multiple Apple ID's, you may find the following page helpful:

Download the current GarageBand version to a computer's iTunes library, go to the device, sign into the iTunes App Store with the Apple ID used to do that, and try downloading it from the list of previous purchases. If that doesn't work and you don't already have a copy of a compatible version, you can't.

Yes i am hoping staff here will look into things, even if i can not get the speeds back what i previously had for near 6 months it would be nice to know why i can not and why the download has dropped by around 10Mb and why my upload is now inconsistant.
Ironically the post concerned got edited because i actually posted the full rather silly reply the Indian call centre made babbling on about down rates rather than the uprate i queried with them.
Bit of a shambles really no real way on BTs web site to contact anyone with regards to broadband issues.
The form which you kindly suggested and i appreciated your help ended up in the hands of someone who either did not bother to read the query or just had such a poor grasp of English they did not understand the query.
Pretty pathetic really when BT are the largest telco in the UK. I think ill be taking my broadband business elsewhere regardless at the end of my 18 month contract, while im sure staff here are wonderful and may even yet help me, i do not particularly want to go through the almost like pulling teeth pain of getting any future issue looked at.
They are great at quickly fixing voice line problems and have a great test on their site. Broadband side of things and support for that though seems a shambles.

I have a problem, from system test says: Error 4mem/61/400000000:0x8444fb98, I know how you can solve. Thanks

If you have Apple Care for that computer, give them a call: Apple's Customer Support - in the US, (800) 767-2775
If you're not sure how to handle the situation, consider walking your MB into the nearest Apple Store and asking someone there to take a look, etc.
Good luck in any case.

I download a driver from the site but the Mac would not open it. This system has an ATI Radeon HD 2600 XT 256 MB graphics card. What do I need to do. Do I need a new Card?

I've had very little trouble in two years. And now I do like Windows 7 but also eager for the RC.
I've been using the latest Nvidia. There is a method to the madness of how to uninstall/delete and install graphics drivers, or madness in the method. The W7 drivers are easier.
Nope. Something else. More sensitive to disk errors. You aren't running a program to boost fans. Something.
And some AV software is more prone to causing trouble. But all you need is a good AV/malware program, and even Norton AV 2009 is acceptable, or Avast or one of the others.

System Profile says LCD

I have a mid-2009 MCP 13". It is supposed to have an LED monitor (and judging by the brightness and battery life, it must have one), but the System Profiler says that it has an LCD monitor. Does anyone know why this might be? I'm running 10.7.
On a separate note, does anyone know the contrast ratio of that display?
Thank you!

LCD is "liquid crystal display" and that describes the layer that contains the acutal pixels. LCD displays nust have some technology for backlighting the pixel matrix for viewing. Older displays used something call cold fluorescent backlighting. Somewhere before the Unibody MBPs were inroduced, the backlighting was changed to LEDs or "light-emitting diodes" to reduce temps and offer better lighting with lower power demands.
So LCD and LED refer to two different parts of the total display assembly. Yours is perfectly normal.

[Gnome3] Is gnome-system-monitor supposed to work?

Upgraded to Gnome 3.0.

Is this normal? Am I missing a library?
I have the following lib installed:
- testing/gtkmm 2.24.0-1
- testing/gtkmm3 3.0.0-1

Gnome-system-monitor mislabels root partition

Since the recent Gnome 2.30.2 upgrades the other day, Gnome System Monitor has oddly started mislabeling my root partition in the "file systems" tab. Every other partition is labeled as "/dev/sda2," "/dev/sda5," etc. But my root partition is labeled "/dev/disk/by-uuid/42d32269-85ca-4567-a3ha-71hj8e0f7838." So the mode of labeling is not consistent, using one type of label for every partition and another type just for my root partition.
The problem with this is that the columns are automatically resized to fit the entire length of the uuid label, pushing information I want to see off screen and forcing me to scroll over to see it or resize the window or or resize the column every time, etc..
I see that the gnome-system-monitor package is still at 2.28.1, so it wasn't upgraded. What could cause this? It's an annoying bug and was not a problem before I did the 2.30.2 upgrades yesterday. I also notice that the Gnome Disk Utility and Gparted do not do this; they label my root partition /dev/sda1.

gnome-system-monitor uses libgnomesu for this. It's a library that does the same things as sudo does.
