Very Computer

Sorry if this is in the wrong group or is mentioned in a faq or howto, but I
am very new to Linux, I'm very experienced in dos/windows but prefer to use
OS/2 for most of my work.

The problem of the day is that I wish to be able change the CD that is mounted
under the directory "cdrom", also I would like to be able to mount floppies.
If I umount /cdrom then I can eject the CD and change it (NEC4xi on AHA1542cf).
After inserting a different CD I try to mount it using

mount /dev/scd0 /cdrom
or
mount -t iso9660 -ro /dev/scd0 /cdrom

I get something like unable to create lock file, and something about file mtab~,
sorry I can't be more precise but I'm at work at the moment.

When I try to mount a floppy using

mount /dev/fd0 /adrive

I get /adrive is not a mount point, or something close.

Can anyone help me please, as I say I am very new to Linux/Unix so plain language
please.
Also is there a Howto or Faq that would be good for someone moving from dos/OS/2

TIA

- the mountpoint (/cdrom /mnt /floppy ,....) that you want to
use must be present ('mkdir /cdrom ' as root to create /cdrom
mountpoint) when you try to mount

- when you want to umount a drive NOBODY must be in its
mountpoint (if you are for example in /cdrom/dir1 you must cd
out of there and all the users logged in mustn't be into
/cdrom)

-configure /etc/fstab for your needs to mantain your filesystem
 (man fstab gives you a lot of informations about it)

I found a lot of infos,tips reading Linux Gazette ,a FREE
magazine online on Internet (sorry I haven't with me the
address; to find it look for 'linux gazette' using NET SEARCH
button with Netscape)

I have s matsushita/panasonic Sound Blaster CD and this is how I mount it:
mount -t iso9660 -r /dev/cdrom /cdrom

This should work for you also, I think.

I'm sure that someone else will respond to this also, so stay tuned...

/dev/hda3        swap        swap        defaults
/dev/hda2        /           ext2        defaults

/dev/hd1a3       /hd1a3      ext2        defaults
                 ^^^^^^this is a bad name for this, but it
                       is just there to take up space, until
                       I actually start using this partition.
/dev/cdrom       /cdrom      iso9660     ro,user,async,noauto
/dev/fd0         /dos/a      msdos       rw,user,async,noauto
/dev/fd1         /dos/b      msdos       rw,user,async,noauto
/dev/fd0         /floppy/0   ext2        rw,user,async,noauto
/dev/fd1         /floppy/1   ext2        rw,user,async,noauto
none             /proc       proc        defaults

for me /dev/cdrom is a link to /dev/hd1b, which is  where the
cdrom drive is attached. To mount to the cdrom I simply:

mount /cdrom

To mount a floppy:

mount /dos/a
or
mount /dos/b
or
mount /floppy/0
or
mount /floppy/1

depending on the drive and file system type.
The "rw,user,async,noauto" is read/write,group user - so that non-root
can mount,async,noauto prevents attempt to mount on boot-up with
mount -a. Each of those mount points /cdrom /dos/a /dos/b /floppy/0 and
floppy/1 must exist as empty directories in order to mount a device
on them.

I get the problem with mtab~ after a failed mount, due to doing
something wrong. I then have to go in and delete /etc/mtab~ so
that I can mount. I don't know if this is proper, but that is
the only way I could find to mount a device at that point.
