Pass it as an option on your floppy entry in fstab as in:

using stock gentoo-dev-sources (should I be using supermount-ng, perhaps instead?) version 2.6.1

I have a 128MB Attache` USB memory stick. Works fine, I can mount it etc.

When I use it with supermount with the following /etc/fstab entry:
none /mnt/stick supermount fs=vfat,dev=/dev/sda1 0 0
.... it also works.. until I unplug it.

After unplugging it, /dev/sda1 no longer exists, nor does /dev/sda for that matter.
Plugging it back in gives me the following in dmesg:

not sure, but try adding "sync" to your options in fstab.

usb devices have a write delay, so if you yank it out, it won't have actually finished writing the data.

it's safer to manually unmount, so then linux can finish writing and you can remove it saefly (like stopping the device under windows)

but this then stops it from being automounted next time I believe.

for kitchen:

The real problem is that supermount is designed to work with removable media devices not removable devices. When you insert/remove a memory stick the kernel treats that like adding a hard drive to the system--it loads the module for the device and will try to remove the module after you eject the device. If you try to run a device like this with supermount, the supermount driver will prevent the kernel from removing the driver properly (supermount will appear to the kernel to be using the device since the device is actually in supermount's control), so it won't work properly the next time you insert it. For these types of devices you would be better off making them automount in the fstab and setting the sync option (or call sync manually before you eject it) to ensure the data is actually written to the device before ejecting.

When trying to access a supermounted device I always get "No such device". I don't know how come. Supermount is loaded as a module. My fstab line looks like this:

Do you need to add "hdc=ide-scsi" to your bootloader maybe? You may need to add that for it to work.

Worth a try.

Later

Koen,

you could try the following:

no worries.. hmm.. u can try emerging "eject" and typing that.

I have actually never used supermount, so I'm not sure how things are supposed to eject.

I assume you press the eject button and it will auto unmount and eject.. but I have never actually tried.. I do everything manually

Make sure you don't have anything in the directory when you try to eject. If a console is in /mnt/cdrom/anywhere, it will not unmount because you are in there. If you have Konqueror open and have went into the CD files, you may have to close Konqueror to get it to unmount. It sort of keeps those files open in case you go back I guess.

That is the same problem I had in Mandrake. You go in and then leave the CD, but it still thinks you are in there. If you close Konqueror or type in cd / it will then eject.

That is my experience anyway. May want to try it.

edit: somebody beat me till I can type. <sighs> :roll:

Got it working, but only by setting fs=iso9660. Might be worth adding this option to the guide.

I'm using gentoo-dev-sources-2.6.1-r1 if that helps anyone work out what's causing auto to fail for some of us.

I just wanted to add my "thumbs up" to all the people who have put valuable information in this thread (and especially to the original poster of course!!)

I successfully installed supermount on my system in 10 minutes, and I like that.

Such howtos are really much help for noobs like me!

Thanks!

Ditto to the supportive comments of several others who gave an unconditional thumbs-up to the originator and contributors of/to this thread.

I first installed Gentoo and began playing with it in April '02; for some reason I could never get devfs to work and properly identify/enable my removeable-media devices (obviously the problem was me and not devfs, but that didn't matter when I couldn't figure out how to get it working). So I would always fall back on SuSE. After a while I'd come back to Gentoo and tackle it again but run into the same problem. With supermount everything works, and I don't even have to jump through any hoops!

Thank you!

hmm... in follow up...

supermount works well on the cdrom... love it.

tried it on the 6 in 1 USB card reader and it worked at first but then didnt work... further investigation revealed that the problem had nothing to do with supermount really. It seems that devfs isnt getting updated everytime the flash disks are inserted. In other words, sometimes i stick it in and /dev/sda1 pops up and i can mount it and life is good. Other times I insert it and nothing pops up. Same with the second slot (/dev/sdb1) this has nothing to do with supermount really but does anyone know what might be causing this or have any suggetions?

hotplug is in charge of that kind of thing (I think...)

Is it installed/running at startup (rc-update show)

Arrgh! Supermount was working great with gnome: icons even installed on desktop and worked. So I installed kde (because I like its configurability), and I can't get it working now. I could always go back to using gnome, I guess, but ....

Anybody else have a similar experience? or able to point me in a direction that may help me fix it?

Please tell me how to format floppies when supermount is ON?
