USB Automount Thunar-Udisks-GVFS

I use Archlinux on a few of my desktop machines. I use XFCE and am for the most part satisfied. The one problem that I have with XFCe is thunar-volman and the fact that one cannot pass mount options to the devices that you mount via the GUI. Even when I set the device up for automount through thunar-volman I cannot find a place to pass my command line options. It seems that thunar-volman uses a combination of gvfs and udisks to mount the disks. To fix this I tried a number of solutions autofs was my first try and for the most part seemed to work. The only problem is that it was not interacting with udisks or gvfs really. I may have been able to pass some options to the autofs mount command and get it to interact with gvfs but I did not explore that option. After quite a few people telling me that autofs was buggy and outdated anyways (I was having problems too) I decided to see if I could get thunar-volman to mount right.

I could not do it and instead of messing about with thunar-volman any more I decided just to have devmon taken out of the archlinux aur to do the automount work for me. It automounts, and I think that it was passing the options that I wanted. The instructions for using devmon are here: https://wiki.archlinux.org/index.php/Udev#Automounting_UDisks_Wrappers and the devmon site is here http://igurublog.wordpress.com/downloads/script-devmon/

I stopped playing with devmon because it did not look like it was passing the --mount-options that I wanted.

So screw everything above. I used a combinition of udev and udisks to automount the sticks and pass the async command.

How I did It: Mount under /media; use partition label if present

The following udev rule set automatically mounts devices/partitions that are represented by /dev/sd* (USB drives, external hard drives and sometimes SD cards). If a partition label is available, it mounts the device to /media/<label> and otherwise to /media/usbhd-sd* (ex: /media/usbhd-sdb1):

/etc/udev/rules.d/11-media-by-label-auto-mount.rules
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"

The above file needs whatever options you would like to add to it.

This is my file:

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

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

I think I put one to many asyncs but at the moment...whatever.

You need to restart udevd with:

udevadm control --reload-rules


Resources:

Office 2007

Install

(10.25.11)

This works great:

From forum post: https://bbs.archlinux.org/viewtopic.php?id=86436

Note: You should never run wine commands as root. Run it as your user.

...to get office 2007 working for me I installed bin32-wine, winetricks and then ran:

$ WINEARCH=win32 WINEPREFIX=~/win32 winecfg
and set windows to xp and then ran:
Note: See winetricks section below!!!
$ WINEPREFIX=~/win32 winetricks msxml3  gdiplus riched20 riched30 vcrun2005sp1 allfonts
$ WINEPREFIX=~/win32 wine setup.exe
and then to actually use any of the executables you must cd to the directory. IE:
$ cd ~/win32/drive_c/Program Files/Microsoft Office/Office12
$ WINEPREFIX=~/win32 wine ./EXCEL.EXE

You could set WINEPREFIX in your bash_profile, or make 32bit wine your default (then you only have to do WINEARCH=win32 winecfg). Anyway the two main problems I had were accidentally emulating 64bit (I know Wine Is Not Emulation) windows instead of 32 bit. Also I found that the programs hang if I didn't cd into the directory, probably because the dlls are linked with the local directory. Anyway everything works this way.

Note: I did not have to run via command or script like the guy does though. To execute the software I could just open it from the applicaiton menu.

Office 2k7 SP2

Download from: http://www.microsoft.com/download/en/confirmation.aspx?id=5

Install with:

WINEPREFIX=~/win32 wine office2007sp2-kb953195-fullfile-en-us.exe

Winetricks

The droid font downloader in winetricks is broken. The url is part of the google git project atm. Either the maintainer of winetricks will update or kernel.org will change. I just chose to remove the droid font install from the winetricks script. I think you could create a .netrc file with password information in it but I did not test it or do it this way.

If you visit: http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob_plain;f=data/fonts/ and generate a password in a webbrowser then put it in ~/.netrc , then run the script without comments...might work.

This is what I did:

sudo nano -w /usr/bin/winetricks

USB Device Automount

autofs works but is buggy and outdated.

cpu usage

I am having problem with Firefox and high CPU usage. Lets fix this. I have a feeling it is the flash plugin.

dstat -cdnpmgs --top-bio --top-cpu

Installing with Intel Fake Raid (MDADM)

https://wiki.archlinux.org/index.php/Beginners'_guide#Preparation

at the time: 2015.09.01 iso

All I have done so far was get dhcp running, passwd root, and enabled sshd as I am installing over the network.

On to install:

Looks like it loaded mdadm [1]

ls /dev/md
imsm0  ZERO_0

Lets see more:


# mdadm --detail-platform
      Platform : Intel(R) Matrix Storage Manager
       Version : 5.6.2.1002
   RAID Levels : raid0 raid1 raid10 raid5
   Chunk Sizes : 4k 8k 16k 32k 64k 128k
   2TB volumes : not supported
     2TB disks : not supported
     Max Disks : 4
   Max Volumes : 2 per array, 4 per controller
I/O Controller : /sys/devices/pci0000:00/0000:00:1f.2 (SATA)

Read the next paragraph first please.

mdadm should locate the array and create /dev/md/* entries. If it doesn't do this automatically:

mdadm --assemble --scan

I did not find anything here so lets assemble the array inside the container:

mdadm -I /dev/md/imsm0
cat /proc/mdstat

I saw that the array was in auto-read-only and wondered what the heck was going on so I looked[2] and found that when created, before the first write, that just how they are.

ls -l /dev/md/

So, I bumbled through above, to be honest with you, I do not think any of it matters except possible the command with the -I[3] in it. I do not think that even that matters because it looks like after looking at dmesg the array was found and assembled/reconized at boot. The intel raid utility must have wrote the meta data and such. But just in case I was wrong, I left the above.

SO IT LOOKS LIKE YOU CAN START HERE:

 mdadm --detail --scan
parted /dev/md/ZERO_O

ZERO_0 is my named array inside the imsm0 container[4] so hmm:

fdisk -l /dev/md/ZERO_0

Lets get to partitioning...they say not to partition entire arrays and instead create partitions and assemble them separately but I am not going to do that with intel fake raid.

MBR Install

Doing MBR because my bios does not support EFI, I ran into trouble with HYBRID/GPT, and my disks are only 20GB.

parted /dev/md/ZERO_0
mklabel msdos
mkpart primary ext4 1MiB 100MiB
set 1 boot on
mkpart primary ext4 100MiB 16.5GiB
mkpart primary linux-swap 16.5GiB 100%

Just to see changes:

fdisk -l /dev/md/ZERO_0

Create Filesystem/swap/activate swap

mkfs.ext4 /dev/md/ZERO_0p1
mkfs.ext4 /dev/md/ZERO_0p2
mkswap /dev/md/ZERO_0p3
swapon /dev/md/ZERO_0p3
mount /dev/md/ZERO_0p2 /mnt
mkdir -p /mnt/boot
mount /dev/md/ZERO_0p1 /mnt/boot/
nano /etc/pacman.conf

Uncomment multilib on x64

pacstrap -i /mnt base base-devel
genfstab -U /mnt > /mnt/etc/fstab
cat /mnt/etc/fstab
nano /mnt/etc/fstab

replace UUIDs with:

/dev/md/ZERO_0p1
/dev/md/ZERO_0p2
/dev/md/ZERO_0p3
mdadm --detail --scan >> /mnt/etc/mdadm.conf

Chroot in for config

arch-chroot /mnt /bin/bash
nano /etc/locale.gen

en_US.UTF-8 UTF-8

nano /etc/locale.conf

LANG=en_US.UTF-8

tzselect
ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime

work on some grub stuff

pacman -Sv grub
nano /etc/default/grub 
  • Uncomment GRUB_DISABLE_LINUX_UUID=true
#IGNORE LINE HAS TO DO WITH OLD GRUB *Add mdraid to GRUB_PRELOAD_MODULES
#IGNORE LINE HAS TO DO WITH OLD GRUB GRUB_PRELOAD_MODULES="part_gpt part_msdos mdraid"

Lets finish

Raid Stuff

cat /etc/mdadm.conf
nano /etc/mkinitcpio.conf

Add mdadm_udev to HOOKS=

HOOKS="base udev autodetect modconf block mdadm_udev filesystems keyboard fsck"

Add /sbin/mdmon to BINARIES[5]

BINARIES="/sbin/mdmon"

Regenerate it!

mkinitcpio -p linux
grub-install --recheck /dev/md/ZERO_0
grub-mkconfig -o /boot/grub/grub.cfg
cat /boot/grub/grub.cfg
echo your-hostname > /etc/hostname
nano /etc/hosts
systemctl enable dhcpcd@enp13s0.service
exit
umount -R /mnt
reboot

Remove Disk

HYBRID MBR/GPT

In the end I did not do this, I could not get it to work because I did not have my raid array as bootable so I messed alot up trying to fix something that was not broken. I am keeping this here because I may try it again someday. For now I am doing the MBR method because my disks are only 20GB anyways.

So you have a few options here. I am not using large disks here but I am going with the MBR/GPT hybrid because, well, because. You could do I would think GPT, MBR, or MBR Hybrid.[6]

gdisk /dev/md/ZERO_0

Example from archlinux wiki:

# gdisk /dev/sdX
o  # create new empty GUID partition table
n  # partition 1 [enter], from beginning [enter], to 100GiB [+100GiB], linux fs type [enter]
n  # partition 2 [enter], from beginning [enter], to 108GiB [+8GiB],   linux swap    [8200]
n  # partition 3 [enter], from beginning [enter],           [+1MiB],   linux fs type [enter]
r  # recovery/transformation menu
h  # make hybrid mbr
3  # add partition 3 to hybrid mbr
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): N
Enter an MBR hex code (default 83): [enter]
Set the bootable flag? (Y/N): Y
Unused partition space(s) found. Use one to protect more partitions? (Y/N): N
w  # write table to disk and exit
 v
This will give you total disk size....

  1. DO NOT READ THISSo above, gdisk has an option to add the right flag [0xEF02] to a partition so the bios will find it but someone stated that gdisk lies or was broken. Anyways, I did not do it at first and my system failed to boot. Instead of using the Gdisk way [7] I used parted[8] because I did not read anything about that.
