 |
|
Ever seen anything like this? | Code: | IPSN-JOHNGRAH2 ~ $ mkfs.vfat /dev/fd0
mkfs.vfat 3.0.9 (31 Jan 2010)
IPSN-JOHNGRAH2 ~ $ mount /mnt/floppy
IPSN-JOHNGRAH2 ~ $ mount | grep floppy
IPSN-JOHNGRAH2 ~ $ umount /mnt/floppy/
umount: /mnt/floppy is not mounted (according to mtab)
IPSN-JOHNGRAH2 ~ $ expand -t4 /etc/fstab | grep floppy
/dev/fd0 /mnt/floppy auto noauto,user,noexec,shortname=lower 0 0
IPSN-JOHNGRAH2 ~ $ uname -r
2.6.38-reiser4-r6
IPSN-JOHNGRAH2 ~ $ ls -d /dev/fd*
/dev/fd /dev/fd0u1120 /dev/fd0u1680 /dev/fd0u1760 /dev/fd0u360 /dev/fd0u820
/dev/fd0 /dev/fd0u1440 /dev/fd0u1722 /dev/fd0u1840 /dev/fd0u720 /dev/fd0u830
/dev/fd0u1040 /dev/fd0u1600 /dev/fd0u1743 /dev/fd0u1920 /dev/fd0u800
IPSN-JOHNGRAH2 ~ $ |
There's no error message to sink my teeth into. An older kernel I have lying around (2.6.27) behaves normally.

Shouldn't that be | Code: | | mount /dev/fd0 /mnt/floppy |
? |

If it's listed in your fstab you only have to specify the device or mountpoint and mount knows what to do.

never seen that...
What defaults does the other kernel use? cat /proc/mounts | grep floppy
once the floppy is mounted?

Well, the /etc/fstab is the same, 'cause the root filesystem is the same. I'll check & report back.

Anecdotal: Several weeks ago while using floppies on a pentium 3, I had a very similar issue. I found that if I edited /etc/fstab to:
| Code: |
/dev/fd0u1440 /mnt/floppy auto noauto,users 0 0
|
It would mount the floppies. For some reason mount just couldn't guess the format size. After an update ( for baselayout2 and openrc),
the above stopped working. I haven't test with /dev/fd0, since I hardly ever use the floppy drive.
I hope that might point you in right direction. |

That actually worked. I thought I had tried that before but I apparently had not. Thanks.

It looks like I am having this problem with the mounting of the floppy silently failing if I start the KDE environment. My floppy cannot mount after I start KDE (it silently fails), even after I log out of KDE back into the shell.
I tried the rw option under options in /etc/fstab but it didn't seem to help either:
| Code: | | /dev/fd0 /mnt/floppy auto noauto,user,rw 0 0 |
Note that mounting the floppy works in the shell until I start KDE. It will not work again even after I log out of KDE (will silently fail), until I reboot the system.
Any ideas? |

| Posted: Wed Apr 11, 2012 8:27 am Post subject: udisks command works but mount command does not |
|
|
| Code: | $ uname -a
Linux gateway9300 3.2.1-gentoo-r2 #8 SMP Tue Apr 10 22:14:05 BST 2012 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux |
My machine's internal floppy drive isn't mounting either. Entry in /etc/fstab look OK:
| Code: | | /dev/fd0 /mnt/floppy auto rw,noauto,user,sync 0 0 |
The device is definitely present, and I'm in the floppy group:
| Code: | $ ls /dev/fd*
/dev/fd0
/dev/fd:
0 1 2 3
$ ls -la /dev/fd0
brw-rw---- 1 root floppy 2, 0 Apr 11 08:23 /dev/fd0
$ groups
lp wheel floppy cron audio cdrom video cdrw usb users portage |
When I try to mount the floppy it does not mount correctly:
| Code: | $ umount /dev/fd0
umount: /dev/fd0 is not mounted (according to mtab)
$ mount /mnt/floppy/
$ ls /mnt/floppy/
$ cp ~/test_file_1.txt /mnt/floppy/
cp: cannot create regular file `/mnt/floppy/test_file_1.txt': Permission denied
$ su
Password:
# cp ./test_file_1.txt /mnt/floppy/
# ls /mnt/floppy/
test_file_1.txt
# umount /dev/fd0
umount: /dev/fd0: not mounted
# exit
exit
$ ls /mnt/floppy/
test_file_1.txt
$ cp ~/test_file_2.txt /mnt/floppy
cp: cannot create regular file `/mnt/floppy/test_file_2.txt': Permission denied
$ |
Yet udisks command mounts the floppy without any trouble:
| Code: | $ udisks --mount /dev/fd0
Mounted /org/freedesktop/UDisks/devices/fd0 at /mnt/floppy
$ cp ~/test_file_2.txt /mnt/floppy
$ ls /mnt/floppy/
test_file_2.txt
$ rm /mnt/floppy/*
$ ls /mnt/floppy/
$ udisks --unmount /dev/fd0
$ ls /mnt/floppy/
test_file_1.txt
$ |

|

Thought it best to make a new post, rather than edit my previous post, in case posters here had already read my previous one.
Apparently this is a known bug in udisks: see freedesktop.org Bugzilla Bug 30283 - regression: udisks-daemon keeps forcibly unmounting floppies and Ubuntu Bugzilla Bug Report No. 441835.
As per Comment #344 in that Ubuntu bug report, I edited the following section in /lib/udev/rules.d/80-udisks.rules and replaced the "1" with "0", then rebooted:
| Code: | ##############################################################################################################
# PC floppy drives
#
KERNEL=="fd*", ENV{ID_DRIVE_FLOPPY}="1"
# USB floppy drives
#
SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="08", ATTRS{bInterfaceSubClass}=="04", ENV{ID_DRIVE_FLOPPY}="1"
# ATA Zip drives
#
ENV{ID_VENDOR}=="*IOMEGA*", ENV{ID_MODEL}=="*ZIP*", ENV{ID_DRIVE_FLOPPY_ZIP}="1"
############################################################################################################## |
It didn't solve the problem in my case, so, as a work-around, I have created two desktop configuration files with floppy disk icons on my Desktop: one named Mount_floppy to run the command udisks --mount /dev/fd0 and the other named Unmount_floppy to run the command udisks --unmount /dev/fd0. That is better than nothing but it is frustrating that this bug has been left unfixed for two years. OK, the 720/1440 KB floppy drive has been obsolete for several years now, but there must still be in use quite a few legacy machines with internal floppy drives, especially in back offices.
