Question "fs type supermount not supported by kernel"


hi all, i really hope you will be able to help me. i have compiled 2.6.8.1 kernel on my mdk10off machine and have one problem during bootup, massage is: "fs type supermount not supported by kernel". what can i do? by google i went to http://mandrakeusers.org/lofiversion...hp/t15597.html ; and near end one person says something about "magicdev" thing, what is this? new name to supermount (or somthing that has replaced supermount?). i have this magicdev, rpm -q magicdev gives me: magicdev-1.1.5-6mdk. do i have to remove this beast [on site i told upper about this guy asks hot to turn this magicdev thing on, isn't the point to turn it off not on?].

The problem you have is that you're running
Mandrake. Mandrake and stock-kernels is a
bad idea, try to get a kernel 2.6.8 from the cooker
rather than rolling your own.


Cheers,

ok, got it, but isn't there really any way to have own compiled kernel on mandrake? it is really faster.

You could ask on the MDK-list which patch they
use to get "supermount" functionality.

I don't know how safe it would be to modify fstab
to get your new (own) kernel to work, a mate of
mine for instance broke CD-burning in MDK 8 that way...


Cheers,
Tink

An alternative to supermount is submount. Unlike supermount submount can be compiled as a module so you don't have to patch your kernel. I have used them both (supermount and submount) and I think submount has supermount beat "hands down".

I use stock kernels with mandrake, but then I use it because I don't like supermount and because supermount generally is what locks mandrake up at regular intervals. mdk 10 runs very nice with a stock kernel and no supermount... (KDE does good mounting anyway, so it's redundent)

BTW the stock 2.6.8.1 kernel will break cd burning. You need to bypass a couple of lines of code to remove the new security features til everything catches up.

you can do

supermount - i disable

to disable supermount and change the fstab if that's what you mean? Not sure which kernel we are talking about. I'll assume 2.6.8.1

The 2.6.8.1 kernel just stops k3b from working... and cdrecord I think, though it may still run as root... I couldn't get anything working. To fix it I had to comment out a couple of lines of code and recompile... Not sure if it affects all systems or not, but it did mine. Doesn't seem to do any damage to the drive tho, just won't recognize the drive as a burner, just a rom...

in the file drivers/block/scsi_ioctl.c you have to comment out lines 196 and 197 and recompile it. so it looks like:

/* if (verify_command(file, cmd))
return -EPERM;
*/

And then I could burn again. I think there may be a 'better' patch maybe, but I'm holding out for the next kernel

Just a warming. It's near midnight here is Australia and it's been a long day and I could be talking total cr*p... Or at least somewhat less that acurately...

yes, i am talking about 2.6.8.1; you're right, as a normal user i am not able to burn any cd but as root it works (hey, this is quite a good protection before someone not to waste my cds ), so this is a little problem for me.
and thanks you all guys for helping me with my problem in this topic
