I have 4 drives. Two identical pairs. Each pair does something different and serves a different purpose to my system. Can I set up two RAID 1 arrays?
500gb/500gb = Raid 1
250gb/250gb = Raid 1
Can I do this with Ubuntu's software raid?
I have a server that has one drive with Ubuntu already loaded on it. I would like add another drive and then create a mirrored RAID between the two.
View 4 Replies View RelatedI was wondering what is the proper way to setup a hardware based mirrored raid. I have two 2TB drives and a nvidia based raid on the motherboard. I used the nvidia raid manager to setup a Mirrored array consisting of those two drives. The total shows as 1.81TB array.
I boot into OpenSuSe 11.3 and in the partitioner I see two drives (dev/sda and dev/sdb each 1.82TB) listed instead of a single RAID drive. Am I doing something incorrectly that two drives show up instead of the array? Does something need to be enabled?
I've installed Debian Squeeze twice using CD1. First time with a high-speed internet connection using a mirror, 2nd time without. With a mirror, much more is installed, and clearly a much more complete installation. What packages would I install to make a basic CD install more like a mirrored install? Is there a list on the CD somewhere?

One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:

I often use dvdbackup to mirror dvd's to my harddrive. I used to use k3b to burn them to disks. The problem is I no longer use kde, and I realy hate installing kde apps these days, since they seem totaly bloated. Brassero isn't smart enough to take a directory with a dvd's file structure mirrored into it, and burn this as a video dvd. Is there a way to convert such a directory into an iso from the command line so brassero can handle it?

View 5 Replies View RelatedI have 2 drives mirrored via windows software raid and I plan to toss the drives into an Ubuntu server soon where they will also be mirrored. The server will have another drive for booting. What is the best way to get these mirrored drives into ext format while preserving my data? I plan to use software raid in Ubuntu as well. My only idea is to format a 3rd drive as ext and copy all the files over, seems inefficient though.
View 1 Replies View RelatedI have an internal hard drive split between Windows 7 and Fedora 12. The Fedora 12 install exists on a LVM which presents a bit of a challenge when trying to mirror the drive. I was trying to use gparted but it doesn't have support for LVM. I discovered g4l, which does a bit-by-bit copy and ran a full disk copy using that from the 500 GB internal to a 500 GB external. Inspecting it with gparted, the copy LOOKS like it went correctly.
However, when I disconnect the internal and attempt to boot to the external (specifically in the BIOS), it's unable to boot to it. It instructs me to insert bootable media and try again. Has something gone wrong with the copy? It SEEMS like g4l finished faster than it should have given the copy rate it was operating at (I had figured out when it should finish up), but the screen saver had been on and when I came back it was back at the menu, so I don't know if it got to 100% or ended prematurely? There were certainly no error messages...

I am trying to setup Dual monitors with individual (non-mirrored) desktops. AMDCCCLE will only identify the monitor I want to use as primary as number 2 and the monitor I want to use as secondary as number 1 - I have tasksbars, awm, desktop items configured to use the first screen and the second screen is clear for media use. The choice seems to be determined by what output port on my graphic card.. whatever monitor is attached to the HDMI port is called 1. xrandr can only identify the 2nd monitor - the first monitor is unknown I've attached my xorg.conf

I have been searching for an answer to this, and have come up dry.
I have an HP OfficeJet Pro 8500 a909a. It was working fine until recently. Now when I go to print duplex, the second page is mirrored vertically and rotated wrong.
I suspect that a recent update to HPLIP has caused this, but there may be something else in play with the GS utilities also. The problem is that I have no idea about how to fix this. I was hoping an update would show up and a simple "yum -y update) would fix things. That still has not happened.
I am a student and would like to save paper, at least with my draft copies, but this makes duplex printing impossible.

When I reboot my computer, my iptables sets itself to a policy of dropping everything, adds a bunch of rules, and a bunch of extra chains, to the effect that (due to everything being set to drop) I can't do anything. I know how to fix this from the terminal to the extent of just clearing most of it and changing the policies back. However, what I don't know is how to make it stay that way. I have a file with the iptables rules I want, so every time I start up I just run iptables-restore, but I don't want to have to do this every time, particularly since others use this computer who do not have admin privileges.
I've tried changing /etc/network/interfaces with the added code pre-up iptables-restore < (etc) But that never does anything, or if it does it just makes stuff work even less. I've tried changing init.d before based on similar info elsewhere, still no luck. I don't know how to get it to stick, and I don't know why it is defaulting to the rules it is, other than that I used a firewall app a while ago and afterwards this was the result, for which I uninstalled that app after no success using it to reverse the damage.

In light of my previous achievement in wireless networking, I've decided to create a larger issue for myself to solve. Which hopefully I can get some help with. Because my system is totally kisspoped up, for those of you who get what that means. I was trying to install GRUB via the .txz package and it created a mirrored image of the /boot folder. Which for some reason contained the / folder. Which in turn held /boot and all the other folders / is expected to contain.
Now, trying to remove the extra /boot folder proved difficult, but once I finally was able to figure it out, I remembered I could removepkg and that would probably mend the situation. However, I was already 20-something percent through moving the files to trash. Now when I checked /, /boot was gone from there. Along with various other folders. SO! Apparently the /tmp/boot folder created was in reality the /boot folder, albeit in the wrong place and having the wrong contents. Somehow, one folder existed as two different versions of itself at the same point in time. Much as a Time Lord might. Deleting one made the other vanish with it.
Good news:I removed it via Thunar and it should be in the root user's trash /home and some other folders had yet to be trashed when I hit cancel, so I can still use some things Bad news:I never ran X as root, so I don't know if it HAS a trash folder I can only use things already started up because the binaries are gone, but the configuration files in /home are still there (although /usr/bin remains)
Ideally, there would be a big UNDO button somewhere in this long row of function keys. Reasonably, there should be some kind of restoration tool. Realistically, I think I'm going to have to reinstall the system, which wasn't easy in the first place due to my faulty disc bay which detects discs at will.

I don't start a network connection when my machine boots FC11 64 bit. When I start the connection and the Firefox browser, I always find that Firefox has set itself to work offline. I use File->work offline and uncheck that box. This fixes the problem, but only till the next reboot. Even if I exit Firefox "in an orderly manner", the next time it will have set itself to work offline.
I had this problem in previous Fedora versions. I read about two solutions on the web. One was to write a script that removed a file called extensions.cache before Firefox ran. The other was to type about:config in the address bar of Firefox, acknowledge the warning message, and use the right mouse button to togglethe value ofoolkit.networkmanager.disable from "false" to "true".Are either of these good solutions? What exactly does "network manager" do? I think of it as the gui under System->Administration->Network, but it must be more.
When I installed Slackware, I deselected a few software sets like KDE and TCL, but now I would like to install KDE (btw, what is TCL for? Is it something important that I should have installed, or is it something like "if you don't know, you don't need it"?). What would be the best way to install the KDE software set and even have a menu to deselect a few packages I know I won't use?produces a list of kde packages (including the kde language packages), but I don't know if that's everything in the kde set. It seems like it's not, since it's transcending the software set boundaries to provide options for the internationalization packages, too.

Two part question:
1. what tools are recommended for designing web pages?
2. What tool sets are recommended for maintaining them?
I suspect that the first question really addresses the second rather than the literal question because of the source of the request. Here's the environment. A small church wants to post and maintain a website. Various non-tech persons will be responsible for maintaining much of
the content of the site. This tells me that they want/need a site that contains the necessary content maintenance tools within the site itself, not a tool on the individual desktops with the only real need for the design/dev tools being for initial construction of the site and a GOOD book on site design to guide construction of the site in the first place.
