[solved] how to prevent my sdb1 from being double mounted

Hiya friends :)

i recently migrated my /home directory from /dev/sda2 which is mounted as '/' to /dev/sdb1 which is now mounted at '/home' (previously /media/sdb1)

the weird thing is that it seems to be double mounted now (the usbhd entry)

anyone know why this happened and what to do against it?

Thanks
Arien

Re: [solved] how to prevent my sdb1 from being double mounted

Do you have a udev rule (from the wiki, say) that mounts sd* drives to /media/usbhd-sd*?

Re: [solved] how to prevent my sdb1 from being double mounted

You running KDE? I know it has a manual setting to mount removable devices whenever they are detected...

Re: [solved] how to prevent my sdb1 from being double mounted

yeah you were right, I got a mount rule there. I think I added it in order so that usb sticks are properly mounted. Hmm any way other than just deletring the rule?

KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"

# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"

# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"

# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask\
=002"

# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%\
k /media/%E{dir_name}"

# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media\
/%E{dir_name}"

# Exit
LABEL="media_by_label_auto_mount_end"

don't delete it!

just change the rule so it doesn't match sda or sdb:

# make this
KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"

# into this
KERNEL!="sd[c-z][0-9]", GOTO="media_by_label_auto_mount_end"
