efs fs module

I tried this questions to some people, but I was suggested to post here.

I would like do a clean install of IRIX on an Indy, but the Indy does not have a CDROM. I have a linux box, running RedHat 5.1, with a CDROM located on the same network and was wondering if there is a way to mount the install CDs on the linux box so that the Indy can read it. What I've read is that there is a read-only efs module floating around, but I can not find anywhere to download it. The only other reference was efsmod 0.6, but it said that it is not usable on 2.1.x kernels of linux. Any help would be appreciated.

After a re-install of IRIX is completed, I could help by doing a linux load on it, but I'm a newbie to the SGI/IRIX world, and may need a little help.

thankyou,
chad

I think I was one of those people; sorry for not responding earlier. (Insert generic whiny excuse about travelling and mail backlog and stuff.)

The state of the EFS code in the linus CVS tree is this:
- prior to the most recent kernel merge (to 2.1.131), the code in fs/efs was able to mount and read EFS partitions, provided that they did not involve indirect extents. Symlinks and stuff all worked, although building as a module did not.
- once I merged to 2.1.131 (and then checked in the EFS code), I started to see very odd behaviour; specifically, the inode-mode checks for directory/file/socket/etc. were failing in ``impossible'' ways. I can post more about that later, but if you've got an EFS partition handy, just build with -DDEBUG_EFS and try to mount it. You'll see the error message in question. On the bright side, module-loading works well.
- I have efslook code here as well, and was in the process of comparing its indirect-extent algorithm to my own when I did the 2.1.131 merge of my code, so maybe once I get past that inode-mode problem I can finish it up? Oh, to dream.

Hope that helps answer your question.

Chad,

Can't make any gurantees but..... Do you have any SCSI cdrom drives laying around? They don't all work, but some do. That would be the easiest fix, if it works. If you need any help with the IRIX load, I can help you off line. Besides, us Chads need to stick together.

Regards,
Chad
