[gentoo-user] gnome-volume-manager

[Iain Buchanan]

Hi,

due to the recent discussions about automounting usb drives, I thought
I'd try gnome-volume-manager again.  I compiled it, started dbus and
hald, started gnome-volume-manager, restarted gnome (just in case), but
when I plug in a drive I get (in /var/log/messages):


Feb  7 10:31:08 orpheus FAT: utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!
Feb  7 10:31:08 orpheus Unable to load NLS charset utf8
Feb  7 10:31:08 orpheus FAT: IO charset utf8 not found

hmmm, why can't it find utf8?

thanks,

Make sure you have the utf8 charset compiled into your kernel - in my 
menuconfig it's File Systems -> Native Language Support -> NLS UTF8  
(the bottommost option).  Also under File Systems, you can change the 
default code page and IO charset for vfat filesystems, which should 
remove the warning.

HTH.

any suggestions for these last two?  I don't really have much of an

I left them as is, and compiled nsl_utf8 as a module (so I don't have to
restart).  When I load the module and plug in the
drive, /var/log/messages now shows:

Feb  7 22:07:18 orpheus FAT: utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!

but the drive still mounts...

Depends on your location and what NLS you normally use.  I'm in North 
America, so I use the ISO 8859-1 charset and code page 437, both for 
Western European language support.  If you don't intend to use your 
computer in any language other than English, those are probably fine.

This is a warning, not an error.  You can use Unicode on vfat 
filesystems, but it's not recommended as vfat is not usually used in a 
case sensitive context.

So what do I do if I don't want it to be case sensitive?  If I don't
load nls_utf8, then I can't access the drive... But to access the drive
I need nls_utf8...

hmmm....

 From man mount:

Mount options for fat
       (Note: fat is not a separate filesystem, but a common part of the 
msdos, umsdos and vfat filesystems.)
<snip>
       codepage=value
              Sets  the  codepage for converting to shortname characters 
on FAT and VFAT filesystems. By default,
              codepage 437 is used.
<snip>
       iocharset=value
              Character set to use for converting between 8 bit 
characters and 16  bit  Unicode  characters.  The
              default is iso8859-1.  Long filenames are stored on disk 
in Unicode format.


Try compiling the nls_iso8859-1 module, and mount the drive using that 
iocharset.  The man page notwithstanding, the default CP and iocharset 
can both be changed in the kernel config.

If that doesn't work, then I've misunderstood the error/warning, and you 
need to look at the 'utf8' option for vfat in man mount.

Re: [gentoo-user] gnome-volume-manager

[Iain Buchanan]

OK, I finally got some more time to spend on this, and I'll give all
info again, just in case anyone can help.

gnome-volume-manager kind-of works!  When I insert a usb storage drive,
I get this message in /var/log/messages:

[Attached scsi disk blah...]
Feb  9 14:48:31 orpheus FAT: utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!
Feb  9 14:48:31 orpheus Unable to load NLS charset utf8
Feb  9 14:48:31 orpheus FAT: IO charset utf8 not found

But when I mount the drive manually:
sudo mount /dev/sdd1 /mnt/tmp
or
sudo mount -o codepage=437,iocharset=iso8859-1 /dev/sdd1 /mnt/tmp/

it mounts fine, gnome-volume-manager detects that I've mounted it and
opens a window in the "root" folder of the drive (/mnt/tmp).

So why doesn't it do it automatically?  I tried building the module
nls_utf8.  When I load the module and plug in the
drive, /var/log/messages now shows:

Feb  7 22:07:18 orpheus FAT: utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!

but the drive still mounts...

This doesn't seem to be the right way to go, as I can mount the drive
_without_ nls_utf8, but gnome-volume-manager can't...

thanks for any comments!

Not sure.. is UTF8 compiled in? I don't get this warning at all.

$grep -i utf /usr/src/linux/.config
CONFIG_NLS_DEFAULT="utf8"
CONFIG_NLS_UTF8=y

$egrep -i '(437|8859)' /usr/src/linux/.config
CONFIG_FAT_DEFAULT_CODEPAGE=437
CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"
CONFIG_NLS_CODEPAGE_437=y

hmmm, my options are different slightly:

> CONFIG_NLS_DEFAULT="utf8"
> CONFIG_NLS_UTF8=y

CONFIG_NLS_DEFAULT="iso8859-1"
# CONFIG_NLS_UTF8 is not set

> CONFIG_FAT_DEFAULT_CODEPAGE=437
> CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"
> CONFIG_NLS_CODEPAGE_437=y
> CONFIG_NLS_ISO8859_1=y

same as mine.

let me try that and see...

So GVM is trying to force it to utf8.  I would try two things:

1) I'm not familiar with GVM at all, but see if there's an option 
somewhere to make it *not* mount vfat partitions as Unicode.

2) Failing that, make gvm USE -unicode -utf8.

HTH.

I *think* gvm uses fstab to override defaults.
You can try to add an entry for your usb device to /etc/fstab
 
/dev/sdd1	/gvm/mountpoint	vfat	noauto,user,codepage=437,iocharset=iso8859-1	0

could do, but I have multiple drives (media readers, external hd's, etc)
so I can't do this for all of them, especially when I plug them in
random orders.  And I don't want to play with udev (just yet :)

udev is great for this.
As an example I'll try to go through the config for my usbstick.
With my thanks to http://www.reactivated.net/writing_udev_rules.html for the 
great guide, here comes the cliffnote version :)
My usbstick comes up as /dev/sdc

# udevinfo -a -p $(udevinfo -q path -n /dev/sdc)
<snipped>
  looking at device '/devices/pci0000:00/0000:00:02.1/usb1/1-9':
    ID=="1-9"
    BUS=="usb"
    DRIVER=="usb"
    SYSFS{configuration}=="Storage"
    SYSFS{serial}=="ABCD12345678"
    SYSFS{product}=="2.0 Card Driver"
    SYSFS{manufacturer}=="Singim"
    SYSFS{maxchild}=="0"
    SYSFS{version}==" 2.00"
    SYSFS{devnum}=="5"
    SYSFS{speed}=="480"
    SYSFS{bMaxPacketSize0}=="64"
    SYSFS{bNumConfigurations}=="1"
    SYSFS{bDeviceProtocol}=="00"
    SYSFS{bDeviceSubClass}=="00"
    SYSFS{bDeviceClass}=="00"
    SYSFS{bcdDevice}=="014f"
    SYSFS{idProduct}=="2005"
    SYSFS{idVendor}=="0dda"
    SYSFS{bMaxPower}=="500mA"
    SYSFS{bmAttributes}=="80"
    SYSFS{bConfigurationValue}=="1"
    SYSFS{bNumInterfaces}==" 1"

I've removed some device entries returned by udevinfo, but this is the device 
entry that is usefull for what I want. It gives us information on how I can 
let udev recognize the usbstick.

    BUS=="usb"
    SYSFS{serial}=="ABCD12345678"
    SYSFS{product}=="2.0 Card Driver"
    SYSFS{manufacturer}=="Singim"

These are the keys I'll use to match the usbstick, udevinfo already formatted 
them for use in udev rules.
Note: You cannot mix keys from different device entries!
I've chosen the device entry /devices/pci0000:00/0000:00:02.1/usb1/1-9, so I 
can only use keys from that device in the rule. 

The only exception are global keys, KERNEL (the kernel device name) is a 
global which can be used with all device entries. The usbstick came up 
as /dev/sdc, so I can use this in for the KERNEL key.

KERNEL=="sd*"

This will match sda2, sdb, sdc1 etc. so it doesn't matter in when the usbstick 
is inserted or how many partitions are on it. Now I should have enough keys 
to distinct the usbstick from other devices, I only need to name it.

NAME="%k"
%k is replaced with the kernel device name (sd*)
Note: I'm using = for assignment instead of == for matching

And now the most important part, a symlink with a fixed name so even us humans 
can recognize the usbstick. Now I will always be able to access the usbstick 
on the same location, the symlink will always point to the device file of my 
usbstick.

SYMLINK="singim%n"
%n is replaced with the partitionnumber of the drive
It creates a symlink to the value in NAME

Now I have all the data to complete the rule, the keys are seperated with a 
comma ',' 
Note: this goes on 1 line !!!
# cat /etc/udev/rules.d/10-local.rules
KERNEL=="sd*",   BUS=="usb ",SYSFS{serial}=="ABCD12345678 
",SYSFS{manufacturer}=="Singim",SYSFS{product}=="2.0Card Driver", NAME="%k", 
SYMLINK="singim%n"

After you've added/changed a rule run udevstart to let the changes take effect
# udevstart

If the device didn't show up you probably made a mistake in the udev rule

# ls -l /dev/singim*
lrwxrwxrwx 1 root root 3 feb 10 01:39 /dev/singim -> sdc
lrwxrwxrwx 1 root root 4 feb 10 01:39 /dev/singim1 -> sdc1

Done!
No matter what, my usbstick can always be accessed through /dev/singim

Note: http://www.reactivated.net mentions something about GVM not being able 
to use symlinks, in that case you could swap the NAME and SYMLINK values.
NAME="singim%n", SYMLINK="%k"

Good luck :-)

I know, but look at the length of your udev howto - It doesn't compare
to gvm, which should do it as simply as emerge then plug-in.  Especially
if I'm setting up multiple machines, for any arbitrary usb-disk - what
then? udev rules can't help me.

thanks anyway :)

hey, can you tail /var/log/messages for me when you plug in a drive, and
tell me if you see:

Feb 10 14:26:38 orpheus FAT: utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!

I just recompiled my kernel like yours, above, and I still get this
message (but at least g-v-m auto mounts the drive :)
