Conky not displaying lua graph of used space on second hard drive

I am running Conky 1.10 on my laptop. I am adapting the "ConkyBar" configuration by N00by4Ever, located here: http://n00by4ever.deviantart.com/art/Co … 5#comments, to my laptop. It has been a fun and long learning experience for me. However, I have run into a brick wall. I have 2 hard drives, an SSD and a standard drive in 2 separate Conky instances. I can get the percentage used via a lua graph for my SSD instance, but I am having an issue getting it to display the data for the standard drive.

Here is the conky configuration file for the standard drive:

conky.config = {
-- ------------------------- Windows Settings
	own_window = true,
	own_window_type = 'normal',
	own_window_transparent = false,
	own_window_hints = 'undecorated,sticky,below,skip_taskbar,skip_pager',
	own_window_argb_visual = true,
	own_window_argb_value = 0,

	double_buffer = true,
	background = true,

-- ------------------------- Position
	alignment = 'bottom_left',

	minimum_width = 313,
	minimum_height = 165,
	maximum_width = 313,
	gap_x = 1227,
	gap_y = 150,

-- ------------------------- Font
	use_xft = true,
	xftalpha = 0.8,
	override_utf8_locale = true,

	draw_shades = true,
	default_shade_color = 'black',

	draw_borders = false,
	draw_outline = false,

	font = 'Monofur:bold:size=8',

-- ------------------------- Color
	default_color = 'DCDCDC',

--------------------------- OTHER
	update_interval = 1,

	lua_load = '~/.conky/ConkyBar/lua/files_ring2.lua',
	lua_draw_hook_pre = 'main',
};

conky.text = [[
${voffset 25}${GOTO 50}${font}File System
${GOTO 50}${font}HDD: ${font Monofur:size=8}${fs_used /media/Mascha}${GOTO 200}${font}Temp: ${font Monofur:size=8}${exec sudo hddtemp /dev/sdb1 | awk '{print $NF}'}

${image ~/.conky/ConkyBar/img/files2.png -p 0,15}
]];

Here is the lua config file used for the graph:

Re: Conky not displaying lua graph of used space on second hard drive

Hi,

provided that you have changed paths are right

...
	lua_load = '~/.conky/ConkyBar/lua/files_ring2.lua',
	lua_draw_hook_pre = 'main',
};

conky.text = [[
${voffset 25}${GOTO 50}${font}File System
${GOTO 50}${font}HDD: ${font Monofur:size=8}${fs_used /media/Mascha}${GOTO 200}${font}Temp: ${font Monofur:size=8}${exec sudo hddtemp /dev/sdb1 | awk '{print $NF}'}
${voffset 75}
${GOTO 50}${font}Read: ${font Monofur:size=8}${diskio_read /media/Mascha}${GOTO 200}${font}Write: ${font Monofur:size=8}${diskio_write /media/Mascha}
${image ~/.conky/ConkyBar/img/files2.png -p 0,15}
]]; 

the LUA script contains only the syntax of a HDD

You also have on line 22

name='fs_used_perc /media/Mascha',            arg='',                  max_value=100,

entered here, which is wrong.
It would here

... arg='/media/Mascha',  ...

be entered. So you need not even this sprain
do with the temperature in the conkyrc.

Hopefully you understand my English.

Re: Conky not displaying lua graph of used space on second hard drive

Is /media/Mascha your SDD drive and recognized as /dev/sdb? Is that where you installed the OS or are you using it for data?

Somewhere in your configuration below "conky.text = [[" you will need a call to the partitions on your other drive, something like:

${fs_used /}

Need to know your partition layout - in a terminal:

lsblk

and post the results.

Re: Conky not displaying lua graph of used space on second hard drive

Is /media/Mascha your SDD drive and recognized as /dev/sdb? Is that where you installed the OS or are you using it for data?

${fs_used /}

and post the results.

Thank you for the reply. /media/Mascha is my secondary hard drive that I have automounted via an fstab edit. Here is the partition layout:

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 238.5G  0 disk 
├─sda1   8:1    0   512M  0 part /boot/efi
├─sda2   8:2    0   222G  0 part /
└─sda3   8:3    0    16G  0 part [SWAP]
sdb      8:16   0 698.7G  0 disk 
└─sdb1   8:17   0 698.7G  0 part /media/Mascha
sr0     11:0    1  1024M  0 rom 

sda is my SSD. It seems that my config file for my SSD works fine. If you would, can I also post the config file for the SSD, and have you check it out as well? I am learning more about the "inside" of Linux. I appreciate your willingness to help me out. Thank you again. For reference, here is what the conky config looks like running at this time:

Re: Conky not displaying lua graph of used space on second hard drive

the conky config? Yes, post that - people that are using lua rings will need that one read and make recommendations. Looks like you will need to create a conky config file for your root ( / ) partition on sda2 - for example:

${fs_used /} ${hddtemp /dev/sda}

That should be a straight forward substitution for "/media/Mascha" in the conkyrc.

Then it looks like the "files_ring2.lua" file will need to edited to draw the rings for /  - I don't use lua rings at all so I can't help you there.
