How-to: use USB CD-ROM & software RAID1 on Oleg WL500gp

http://wl500g.info/showthread.php?t=15550

Hi Everybody, I'm using Oleg's 1.9.2.7-10 firmware for 3 months now (on a WL500gp) - thanks Oleg - and it is really great, it works just perfectly ! Since I do not have a desktop PC at my home - I only use a notebook - I really wanted to create a redundant way for storage and because I'm using Xbox for media playing I wanted an external DVD reader to be attached to my router so I can access all my DVD's through samba from my xbox. To achieve this I recompiled Oleg's firmware to include SCSI emulation for IDE/ATAPI CDROM & to include RAID support in the kernel. If you don't want to recompile the kernel yourself these are the steps to achieve both functionalities: CD-ROM: 1. insmod cdrom.o 2. insmod isofs.o 3. insmod sr_mod.o (it might be that the order is not this one, I'm writing this from my head) at this time your cd device will appear under /dev/scsi/... RAID1: 1. insmod md.o 2. insmod raid1.o after this you can create your RAID1 soft array using mdadm. LVM is not needed. Note1: Because the 2.4 kernel contains a bug in md.c you need to replace this file with the correct one (this is described here: http://wl500g.info/showthread.php?p=100925 and it works perfectly when you recompile the kernel) If you need help with this, just contact me. PS. (offtopic) I've a USB hub with 6 USB ports attached to one of the USB ports on the router. This has 2 hard disks linked in a RAID1 array + the DVD reader. This works as intended - no special drivers were needed to support this. The second USB port on the router has attached a 6 in 1 card reader with a 4GByte CF Microdrive. This works as a charm as well

I'm trying to make a raid1 on the asus 500gp and I've saw your thread. But I cannot find the md.o and the raid1.o on modules.tar.gz file you attached. I also have a linux noobie question here should I put the files to make the insmod command see them? Should there be a etc/modules.conf file to make them load on the next boot? If you have a quick how-to would be lovely...Thanks.

(that is 28MBit / sec)[br] So if you have a connection speed higher than this, it will not be fully used for sure.
