shire Posted June 23, 2010 Share Posted June 23, 2010 Hi! Does anyone know if unRAID can be installed on this machine? A friend says, that is doesn't support the "USB-Boot" feature. Bye. Link to comment
WeeboTech Posted June 23, 2010 Share Posted June 23, 2010 You can boot unRAID from devices other then USB, you will still need the USB Flashkey to be accessible and mountable after unRAID comes up. There have been posts of booting from floppy kicker, Local IDE hard drive. It's possible to boot from cd too (with a bit of set up). A CF adapter in an IDE port also works. This is only for the initial boot of bzimage and bzroot. Once unraid comes up, it will try to mount the USB flash (it should see this without issue). it's a fairly modern machine, I'm surprised it does not support USB boot. In any case, if I got it free (or really really cheap) I'm sure I could get it to boot unRAID. It would just take a bit of work and an alternate boot device. Link to comment
Joe L. Posted June 23, 2010 Share Posted June 23, 2010 Hi! Does anyone know if unRAID can be installed on this machine? A friend says, that is doesn't support the "USB-Boot" feature. Bye. Doesn't really matter, you can boot off of a floppy disk, or off of a small partition on a hard disk that is not part of the array, or, you can boot off of a compact-flash card mounted in an compact-flash-to-IDE adapter. I'm using a CF-to-IDE adapter on a Dual Xeon Intel server board I'm playing with to boot from, since the USB port was only a 1.0 speed and I was unable to get it to boot any of the flash drives I had, even the smallest of them. The compact-flash drive looks to the BIOS as a small IDE disk. I made a small FAT partition on the CF card to hold the bzroot and bzimage files. I used "grub" as the boot loader and installed it on the MBR of the CF card. Once booted, the USB drive is mounted as normal since it has the volume label of UNRAID. My CF card has a boot directory with the stage1 and stage2 grub files along with the menu.lst file. It has as its contents something like this: timeout 15 default 0 fallback 1 title unMENU CF tower2 @ hda1 root (hd0,0) kernel /bzimage initrd /bzroot title unMENU previous version @ hda1 root (hd0,0) kernel /bzimage.old initrd /bzroot.old title ubuntu @ hdb MBR root (hd1) chainloader +1 I then just select the CF flash card as the boot device in the BIOS. I have a full ubuntu OS on a hard disk on the same board. I can use the grub menu to boot into it if I desire, or boot into the old version of unRAID (if I rename the old bzroot and bzimage to bzroot.old and bzimage.old) You will need a USB port for the flash drive though if you plan on having more than 3 disks, since the license key must reside on it. This thread describes my Intel Server board http://lime-technology.com/forum/index.php?topic=6482.msg63023#msg63023 and the clues I was given to configure "grub" on it. http://lime-technology.com/forum/index.php?topic=6482.msg64496#msg64496 Joe L.
