Hi

Ive jsut installed gentoo. In all my excietment i didnt realease that my flash disk, or either of my two cd drives are not on my gnome desktop.

I used a stage 2 install. used genkernel and have hotplug enabled.

When i boot it says "hotplugging usb devices"
Code:

# mount /dev/cdrom /mnt/cdrom

mounts my 1st cdrom drive

Whe i try to mount my second:
Code:

jammin # mount /dev/cdroms /mnt/cdrom
mount: you must specify the filesystem type



Contents of /mnt/
Code:

root@tux jammin # /mnt/
cdrom   floppy


My usb drive will be sda, i think, but i cant mount it.

Also how do i get these to be permentaly mounted and for the icons to appear on my desktop?

(me n00b)

Thanks

hi,

all the automount and semiautomatic mounts are located in the file /etc/fstab. by adding a line there for each of your devices (but do NOT change the already existing entries for your harddrive(s)) you can either mount filesystems at boot or with the "mount" command followed by the mount point (e.g. /mnt/cdrom).

first off, make a backup of /etc/fstab somewhere outside of your harddrives (floppy preferably) so you can revert to it if there are any errors with fstab. if there are errors in fstab, your computer might not boot.

if you have all the needed kernel modules for USB mass storage, your USB drives should be named /dev/sdXY where X is a letter starting at "a" and Y is a number starting at "1". usually this means your first USB drive is /dev/sda1.

create a mount point in /mnt (e.g. /mnt/usbdrive) and add this line to your fstab file (changing the /dev/sda1 to point to your USB drive):

Code:
/dev/sda1 /mnt/usbdrive vfat noauto,users 0 0


now you should be able to mount the drive with the command:

Code:
mount /mnt/usbdrive


your second cdrom-drive should be located at /dev/cdroms/cdrom1, if it's there, you can just copy the line in fstab for your first (cdrom0) cdrom. just be sure to create another mount point (the folder in /mnt), each filesystem needs its own mountpoint.

so to sum up, you mount devices by:

- creating a mount point in /mnt
- finding the device name under /dev
- creating an entry in /etc/fstab
- either mount it manually with the "mount" command or have it automount at boot

hope it helps!

the 'you must specify the filesystem type' message appeared because you didnt specify the filesystem. To mount a device not in your fstab that doesnt use iso9660 (the default), you need to use something like:
Code:
mount -t vfat /dev/sda1 /mnt/usb

Where -t vfat is the filesystem type.
fyi, heres my fstab:
Code:
/dev/hda2      /boot      ext3      noauto,noatime      1 2
/dev/hda4      /      reiser4      noatime         0 1
/dev/hda3      none      swap      sw         0 0
/dev/cdrom      /mnt/cdrom   iso9660      users,noauto,ro      0 0
/dev/hda1      /mnt/windows   ntfs      ro         0 0
/dev/mapper/encrypt   /mnt/encrypt   ext3      noauto         0 0
/dev/usbstick1      /mnt/floppy   vfat      noauto,users      0 0
/dev/usbstick2      /mnt/usb   vfat      noauto,users      0 0
192.168.0.9:/usr/portage/distfiles   /usr/portage/distfiles   nfs   rw,nolock,rsize=1024,soft,timeo=75,retrans=1   0 0
