Supermount and kernel 2.6

Message

alexraasch · Post by **alexraasch** » Tue Feb 03, 2004 10:45 pm

Hi, I have the 2.6 kernel running and want to use supermount for my cd-drive. I have tried compiling it in the kernel as well as compiling it as a module.
Here is what I have in /etc/fstab:

none /mnt/cdrom supermount fs=iso9660:udf,dev=/dev/cdrom,--, 0 0

On every boot I get a segmentation fault when it comes to mounting the local filesystems. The systems runs stable however and I can mount the drive manually (which is not what I want of course).

Can anyone help?

i had supermount as a module, ( rememeber /etc/modules.autoload.d/kernel-2.6 for modules for 2.6 kernels ) , i used the following lines in /etc/fstab, don't know if this helps, all worked for me till i changed to -mm sources, they don't come with supermount, strange they used to

# following lines for supermount
none /mnt/dvd1 supermount dev=/dev/dvd,fs=auto,tray_lock=always,user,nosuid 0 0
none /mnt/cdr supermount dev=/dev/scsi/host0/bus0/target0/lun0/cd,tray_lock=always,user,nosuid 0 0
none /mnt/dvd supermount dev=/dev/ide/host0/bus1/target0/lun0/cd,tray_lock=always,user,nosuid 0 0
none /mnt/floppy supermount dev=/dev/fd0,user,nosuid 0 0

You did install the patch right? The thing that comes with the kernel is not the same thing. It just looks like it. Fooled me too.

There is a whole thread in Documentation, Tips and tricks that gives details on how to make it work. I followed it and it worked fine, until I had to go back to my older 2.6 kernel. Now I have to patch again. Crap.

Let me get this correct...

To use supermount on 2.6.1, you have to follow the patch like in the Doc Tips and Tricks thread?

And the patch that you download works with 2.6.1? I've been having lots of trouble with the whole Genkernel 3.0.1 "beta" thing (finially went back to Genkernel 1.

and don't want to mess the whole thing up AGAIN.

That is what I had to do. I had the same thoughts you did. This

Code: Select all

  │ │                     < > Kernel automounter support                                                     │ │
  │ │                     <*> Kernel automounter version 4 support (also supports v3)                        │ │

is not the same thing as supermount. I thought the same thing, but when I applied the patch, it was obvious even to me, once I saw it.

That patch is not that bad. I had trouble in the past with patches, never would put it in, but that one went right in.

That is how I had to do mine. Maybe some other guru will come along and correct me.

Just so you will know, I had to go back to a older version of kernel and it was compiled with the automounter thing. I forgot and left the fstab with the supermount lines. It informed me that supermount was not supported and that some file systems were not mounted.

Now I got to do the patch again too.

Hope that helps or some guru will correct me if I'm wrong.

Actually supermount has (and prolly will have) issues.
Handling such a thing in kernelspace is not that easy/stable/secure.
I had some good expierience with submount and subfs.
Try it, you'll like it

Forgot the link, try freshmeat.

I did have buggy problems with supermount in Mandrake 9.1, on occasion. It would not want to unmount the darn thing. I would have to reboot. I did not have that problem with it in Gnetoo though. It may have been a newer version of supermount too.

I'll search around for that too though. I like trying different things to see which works best for me.

I used to have that problem (the segfaults at boottime) also, this was with some previous versions of the gentoo-dev-sources (I think it was up until 2.6.1). These versions had version 2.0.3 of the supermount patch included, upgrading to 2.0.3a fixed the problem for me. Perhaps the origional poster is running an older version of the gentoo sources which still has this buggy version of the supermount patch?

Newer versions of the supermount patch are here : http://supermount-ng.sourceforge.net/

Link update!

Submount sound promising, will try it out later.
