 |
|
Hey,
Problem: mount shows me, that the filesystem is mounted for user but only root has rights not the normal user.
I mount an usb-stick. The Filesystem is ext3. I write regular for udev: /etc/udev/rules.d/33-usb.rules
| Code: | KERNEL=="sdc2", ATTR{size}=="23592960", SYMLINK+="usb-sdc2-stick",
MODE="0666", GROUP="users"
ACTION=="add", RUN+="/bin/mount -t auto -o rw,user,users /dev/usb-sdc2-stick
/media/usb-sdc2"
ACTION=="remove", RUN+="/bin/umount /media/usb-sdc2" |
The Symling "/dev/usb-sdc2-stick" is create:
/dev/ls -hasl usb-sdc2* => | Code: | | 0 lrwxrwxrwx 1 root root 4 23. Aug 19:19 usb-sdc2-stick -> sdc2 |
mount -l | grep sdc2 =>
| Code: | | /dev/sdc2 on /media/usb-sdc2 type ext3 (rw,noexec,nosuid,nodev,user)) |
shows me, that the device is mounted with "rw" but the user can't create folders or files.
Thanks for help!

Try passing an additional option for mount. Udev rule looks like:
| Code: | ACTION=="add", RUN+="/bin/mount -t auto -o rw,user,users,umask=0 /dev/usb-sdc2-stick
/media/usb-sdc2" |

Hey,
nothing is mount. | Quote: | | mount -l | grep /dev/sdc2 |
is empty.

Hey,
I delete "user,users"(contradictory) and add one line (3rd). I hope this is a neat solution ! ?
| Code: | KERNEL=="sdc2", ATTR{size}=="23592960", SYMLINK+="usb-sdc2-stick", MODE="0666", GROUP="users"
ACTION=="add", RUN+="/bin/mount -t auto -o rw /dev/usb-sdc2-stick /media/usb-sdc2"
ACTIOM=="add", RUN+="/bin/chown -R lovelytux: /media/usb-sdc2"
ACTION=="remove", RUN+="/bin/umount /media/usb-sdc2" |
Thanks for help! lovelytux |

That will not work as hoped, because umount must be performed before removal. Remove that useless rule.
It's sensible to use the flush option, to be confident that writes have been performed, e.g.:
| Code: | | ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},flush,utf8,gid=100,umask=002" |
