[opensuse] Software RAID with existing drive
by Brandon Carl 08 Jul '07

08 Jul '07

Hello, I recently installed a IDE RAID card (Syba Ultra ATA IDE card SILO680) in my linux box and mirrored one of my drives (250Gb) to another 250Gb drive. When this was done, I tried to boot into openSUSE 10.2 and it kept stalling at "waiting for /dev/hda1 to appear." I then decided to just try and boot from my original hard drive, and it stalled on "opensuse hangs runaway loop modprobe binfmt-ffff." I thought that was very odd, so I took out the RAID card and tried to just boot from my one hdd, and it worked, thankfully. Now I am wondering if there is a software alternative to RAID 1 that i can use with my existing hard drive. I have about 100Gb of irreplaceable data under the "/home/spleeyah/" directory, which is on a seperate partition from the "/" directory. I would like to be able to just copy this drive over to the other one and then set it up as a RAID 1 configuration, but I cannot find any information about how to set this up using Yast or any other tools. I found this tutorial: http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html but when I try to find "raidtools" in my software management, it doesn't show up. This is an internet installation with my repository set as: ftp://mirrors.kernel.org/opensuse/distribution/10.2/repo/oss/. Can anyone help me? -Brandon Carl Spleeyah(a)spleeyah.com www.spleeyah.com -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

I changed it to md10 because somehow I accidentally deleted /dev/md0, /dev/md1, and /dev/md2, probably in an attempt to unmount them, lol. I couldn't find a way to create them again, so I just decided to use md10 and md11. I can't imagine this would affect anything, however. /etc/mdadm.conf does not exist on either drive. >> After this I reboot my computer and choose the "Boot from Hard Drive >> A" and then when I try to mount the /dev/md10 as /mnt it says: "cannot >> read superblock".

[opensuse] GRUB Hard Disk Error
by Hugo Garcia 08 Jul '07

08 Jul '07

Hi Working on a Toshiba Qosmio g10. The machine is a dual boot system. It used to have Mandriva 2005 on it. We decided to install SuSE 10.2 on it. We wiped out the old partition and reformatted it, installed SuSE and when we reboot then we get the 'GRUB Hard Disk Error". If we boot off the SuSE DVD then we get the correct menu for selecting SuSE or Windows and both OS with boot properly. We rummaged through the opensuse.org site and kind of figured out that we might need to reinstall the stage 1 Grub component. We have fiddled around with the options with no progess. Any help will be appreciated. thanks -H -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] Problems with Printers and SuSe 10.2
by Robert Smits 08 Jul '07

08 Jul '07

I've just spent three very unproductive hours wrestling with a couple of printers on my SuSe 10.2 desktop. (I've had both printers - a Brother HL-5140 and an HP-1220c connected via USB cables for a without any problem. Both printers print fine to Windows, and the Brother works fine for Linux. The HP-1220c prints a line or two of garbage and spits out the page, repeating on subsequent pages). In 10.1 I did find it easier to configure my printers through CUPS than through YAST, but in 10.2 I can't get CUPS to enter a password at all. I did manage to get the following dialog when I tried to enter a password: BobsDesktop:~ # lppasswd -a rsmits greetings4950 Usage: lppasswd [-g groupname] [username] lppasswd [-g groupname] -a [username] lppasswd [-g groupname] -x [username] BobsDesktop:~ # lppasswd -g sys -a rsmits Enter password: Enter password again: BobsDesktop:~ # BobsDesktop:~ # As root I can access cupsd.conf and edit it, but don't know what to change and the password.md5 file is empty. I've tried everything I can think of to get CUPS to behave with no avail, and that includes switching from USB to Parallel ports, on both printers (one at a time) - it just will not let me add a password - even one for root. YAST isn't any better. I can get the Brother Printer going but it's only mono, and I need my 1220C for large colour pictures. It worked just fine in 10.1. In Yast, I've checked and they're both using different USB ports - and right now I even have the 1220C connected to a parallel port. I haven't got enough hair left to tear any out, but I feel like it. As far as I can tell 10.2 just won't let me print to my 1220C.

[opensuse] 32 bit sigc++2 for 10.1 64bit?
by Michael Fischer 08 Jul '07

08 Jul '07

Yes, its a skype problem. Of course, it fires up just fine on my 32 bit machine at work, but I have a new 64bit machine at home, and despite installing all the 64 bit libraries, skype isn't happy about that library. Google searching seems to indicate that getting the 32bit version of the lib will fix matters up, but I can't seem to persuade YAST to install the 32bit versions. Can't seem to figure out (feels dumb) where to find a 10.1 rpm of the libs online either. Suggestions?

[opensuse] a good small font for developing with gvim?
by Zhang Weiwu 07 Jul '07

07 Jul '07

Dear list I had been developing by open xterm, maximize it, run vim in it. The benefit is it happen to be more than 160 columns wide, allow me to split vertically to edit two related programs each at 80-column width. It has 3 problems: I. sometimes vim in xterm stop responding suddenly, and never coming back, reason unknown; II. my color schema doesn't work because xterm support limited number of colors III. I prefer gvim for its menu. I'd like to select a small font for gvim so that I can maximize vim window and use two 80-column window inside of it without xterm. That way I need a font at 6 pixel wide. I cannot found such a font. in xfontsel I select 6 for pxlsz and only two fonts are available: "clean" and "fixed", both are two small to be readable at 6 pixel (then what font xterm is using that is readable even at 6 pixel??) and both are not selectable in gvim's choose font dialog. Can someone recommend me a 6-pixel-wide readable font (like the one used by default in xterm) and usable in gvim? Thanks in advance! P.S. maybe the best solution is to run at 1280 px wide screen with 8-pixel font, which is 160 column wide, but yet what I need is 161 column wide because there is one column used as separator:( -- Zhang Weiwu Real Softservice http://www.realss.com +86 592 2091112 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org
