How To Install Openfiler From Usb. Tagged install openfiler from usb, install openfiler usb. Is it possible to install OpenFiler from a USB flash drive? Put the fun back into computing. Use Linux, BSD. Random Distribution. KRUDKRUD was a Linux Distribution which tracks Red Hat Linux. It was updated every month, and.

This was something I’ve wanted to do this for a while now. Basically, I’m trying to cut back on the number hard disk drives in my environment.

If therefore decided to install Openfiler on a USB memory stick instead of another hard drive. I could then run 4 750GB SATA drives in RAID10 and leave the Openfiler OS to run on the USB stick.

As most servers can boot from USB, I didn’t expect any issues with installing and booting Openfiler from USB. However, Openfiler doesn’t load the USB storage drivers when it boots by default. You’ll have to tweak the initrd image in order to boot from USB. I recommend you use a 2GB or 4GB memory stick.

Although Openfiler can install in less that 1GB, you still want to leave some free space for logs and swap space. I used the SanDisk Cruzer Micro 4GB as it's a small device (physically) and it's made out of metal and not plastic and should be a little more durable. However, this memory stick also has a plastic sleeve covering the memory stick, which I removed in order to keep the memory stick as cool as possible inside my server. The server I've used is the HP ProLiant ML115 G5. This server has a USB port located on the motherboard which is perfect! As the USB memory stick will be located inside the server, it won't be be dangling on the outside where it can be 'removed' by 'accident'. You know what people are like;-) 1.

Power on the server and boot from the Openfiler 2.3 installation CD. At the Openfiler Boot Menu, type linux expert and press enter.

You have to parse the “expert command” or else the Openfiler installer will not display the USB flash memory as available storage to install Openfiler to. When the installer has loaded, follow the screens until you get to decided whether to manually or automatically partition the drives. For normal installations automatic partitioning should be OK, however, as we will have to do some post install work on the kernel and the fact that we are only installing Openfiler on a 2GB or 4GB volume, we'll need more control over partition device numbers (/dev/sda1,2,3, etc) as well as partition sizes. I’ve therefore created my partitions manually as follows. The reason for making /var/log a separate partition is because the log files can grow to large sizes. Making the /var/log mount point its own partition, protects the / partition from running out of space by growing log files in /var/log 5. Continue with installing Openfiler. As this is now installing on a USB 2.0 device, this may take a while longer than normal to complete.

Mine took a good 50 minutes to install. Once the installation has completed, keep the installation CD in the CD drive and reboot the server, this time booting from the Openfiler CD-ROM again and not from the newly installed Openfiler on the USB stick. If at this point you boot from the USB stick, the Kernel will not load USB storage drivers and won’t therefore be able to mount the root partition.

This will result in a kernel panic. When the server boots from the Openfiler CD, you will again be presented with the boot menu. This time, type: linux rescue 8. When asked to start the network system, choose “ No” 9. At the rescue menu, choose “Skip” 10. At the prompt, create a new directory called system, and mount the root filesystem (/dev/sda3) to that directory mkdir –p /mnt/system mount /dev/sda3 /mnt/system 11.

Now, mount the boot partition to /mnt/system/boot mount /dev/sda1 /mnt/system/boot 12. Change the system root to /mnt/system. This allows you to work from /mnt/system as if it was the root filesystem chroot /mnt/system 13. Now, extract the initrd image in /tmp cp /boot/initrd-2.6* /tmp/initrd.gz && gunzip /tmp/initrd.gz 14. Create a new directory where we can extract the initrd files to and work on them mkdir /tmp/tmp-initrd cd /tmp/tmp-initrd 15. Extract the initrd files to the /tmp/tmp-initrd directory cpio –i /boot/usb-initrd.img cd /boot/grub vi grub.conf Find the line that contains the old initrd file and change the file name to usb-initrd.img Save the grub.conf file and exit. To reboot, type 'exit' twice.

The server should reboot and should now be able to mount /dev/sdb3when it boots from the USB stick. Hello Rynardt Spies Thank You for this post. It is helping me lot. I am trying to install OpenFiler in a usb stick in order to be able to install 4 500Gb hd and creat Raid 5. Unfortunately I am not good with Linux operating systems and during your Step, precisely on 17th step, I as not able to find lib/modules/kernel/drivers. There is not kernel directory in my installation neither drivers.

How can I copy the necessary drivers to /tmp/tmp-initrd/lib/? I am waiting your answer. Thank you in advance. Regards Sergio Sa.

Do a search for “mount –t proc /proc /proc” and add the following underneath this line. We want to load these USB and storage modules before any other modules that’s why these entries need to be at the top of the file.
