Re: [Bug 97655] Re: dmraid45 target please
I don't want or have windows installed. My original intent was to install Ubuntu with LinuxMCE on a raid 5 configuration. I tried using software raid but had issues on setting it up in the Ubuntu setup. When I choose create md devices it says I only have 1 raid partition when it needs a minumum of 3. That's why I headed down the dmraid path. So you are telling me it can be done as long as it's only a linux machine? That is great news. I guess I will try again this evening when I get home from work. On 5/10/07, Chad Bernier [EMAIL PROTECTED] wrote: Yea i figured something like a HTPC might have space limitations. Lesley, unfortunately, the only way to do what you described involves giving up Windows. I have assumed you want windows along with Ubuntu on your PC, because you are using dmraid. If you won't be installing windows, you don't need fake raid at all. you can use software raid already built into linux. That will allow you to set up a raid 0 and raid 5 on the same array, pretty cool :) -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a direct subscriber of the bug. -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 97655] Re: dmraid45 target please
That's good to know. I was about to pull my hair out. I am building a HTPC machine and wanted raid 5 for redundancy. Looks like I will have to use raid 0 and backup the important stuff on a regular basis. Again, thank you for the info.

I hope someone picks up my other bugs, because my raid set won't activate properly. lesley, It sounds like you want to BOOT off your raid5. That isn't going to happen, not anytime soon. I hope you can get it working as a data drive though. To be able to boot of raid5, first the initrd needs to be fixed to include dmraid in it and whatnot. After that's done though, grub still needs to be patched. I might be wrong, but I am under the impression that Grub cannot boot off a raid5 array, although it will work on a raid0. I hope I'm wrong about that, and full raid5 support can be added to gutsy, and will be included in FC7. -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a direct subscriber of the bug. -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 97655] Re: dmraid45 target please
Yeah. The case only holds 3 drives and currently I have 3 500 GB drives installed. Is there a way to raid partitions on each drive? Such as Raid 0 for the root and /home for the raid5 across the 3 drives? On 5/10/07, Chad Bernier [EMAIL PROTECTED] wrote: Lesley, I'm not sure if you can get the boot to work or not, but that isn't your only option. You could simple use an additional Hard drive to boot from, and keep all your data on the raid5 array. That's what I'm attempting to do with this computer as it simplifies the installation of any OS. You won't have redundancy on your OS, but do you really need that? You can just set up a cron job or something to automatically backup your boot drive to the array anyways. The downside is you'll need to get another drive and have room in your case for it. I don't know if that's a deal breaker for you. -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a direct subscriber of the bug. -- dmraid45 target please https://bugs.launchpad.net/bugs/97655 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 97655] Re: dmraid45 target please
Going through the install it didn't detect the raid 5. I manually ran dmraid -ay and received the same error about the raid45 kernel. Do I need to insmod or modprobe in order for it to work?

As you can see, I am having the same issues. I am working from the Ubuntu 7.04 Live CD. I have worked on this for a week and I am about to pull my hair out. Thomas Bitterman, have you finished the Live CD with raid45 support? I don't care if it's a DVD iso. I am desperate at this point and I don't want to give up.
