Installing OpenFiler on a USB Flash Disk
A few days ago I was searching the internet for good articles on installing OpenFiler onto a USB Flash disk for my home NAS storage and I found this article written by “Rynardt Spies” on his site http://www.virtualvcp.com/home and apart from a few issues it was excellent!
I had no issues with steps 1 to 15, the remaining steps have been updated with my experiences.
Step 16: Now we need to edit the init file under /tmp/tmp-initrd/. I like to use vi as my text editor. So, here we go.
- Type “cd /tmp/tmp-initrd/”
- Type “vi init”
- Press “i” to enter Insert Mode
- Using arrow keys find the line with insmod /lib/sd_mod.ko
- Enter the following lines after it
- insmod /lib/rs_mod.ko
- insmod /lib/ehci-hcd.ko
- insmod /lib/uhci-hcd.ko
- sleep 5 echo “Loading USB Storage Drivers”
- insmod /lib/usb-storage.ko
- sleep 10
- Save the file and quit vi:
- Press “ESCAPE” to exit insert mode.
- Type “:wq” to save and exit.
Step 17:
Now we have configured the init script to load some modules when the kernel boots, however, we now need to copy the actual module files to /lib/ directory.
- Browse to drivers directory, Type cd /lib/modules/
Note the next directory will depend on your OpenFiler build version
- Browse to the next sub directory
- Type cd /%Your-Version%/kernel/drivers
- Copy new modules
- Type “cp usb/storage/usb-storage.ko /tmp/tmp-initrd/lib/”
- Type “cp usb/host/ehci-hcd.ko /tmp/tmp-initrd/lib/cp usb/host/uhci-hcd.ko /tmp/tmp-initrd/lib/”
- Type “cp scsi/sr_mod.ko /tmp/tmp-initrd/lib/”
Step 18:
Now we need to pack it all in a .img file and place it in /boot/. We then need to tell grub (the boot loader) where to find it.
- Type “cd /tmp/tmp-initrd”
-
Type “find . cpio –c –o gzip -9 > /boot/usb-initrd.img” - Type “cd /boot/grub”
- Type “vi grub.conf”
- Press “i” to enter Insert Mode, find the line that contains the old initrd file and change the file name to usb-initrd.img
- Press “ESCAPE” to exit Insert Mode and type “:wq” to 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.
Hope this helps.
