So this is what that displays. And I really don’t understand why it is taking up so much space because it worked previously. I don’t know what to remove to give more space?

[sdetweil]

@tkaauf32 thats only of your home folder… usually not a problem

notice I had /

du -a / 2>/dev/null | sort -n -r | head -n 10

[tkaauf32]

Okay so after typing correctly (my apologies, im not very savvy in this)

@tkaauf32 change head -n 10 to -n 20

[tkaauf32]

I hope you can decipher this haha

@tkaauf32 need with head -n 20, to give more lines of output

/opt/Wolfram is taking a bit of space

[tkaauf32]

@sdetweil I pasted the wrong image. Thanks for your patience with me

@tkaauf32 its not the logs… not even showing in the top 20.

that /opt/Wolfram is taking 16.7 % or disk space (1146764/6846289)
/usr/lib & share is taking 53%
I would guess that your memory card is too small…

what size is it?
what did u add last?

[tkaauf32]

@sdetweil I guess I need to delete the wolfram. I’m using an 8GB but I have’t manually changed anything so I’m surprised that it doesn’t work anymore. Maybe the logs put it over the edge.

[sdetweil]

@tkaauf32 logs are pretty small… do the du /var/logs | sort | head thing, just on the logs folder…

[tkaauf32]

@sdetweil Permission denied. Also tried it with /logs and /log. /log says “is a directory” and the latter says permission denied

[sdetweil]

@tkaauf32 sorry, typo

 du  /var/log 2>/dev/null

may need sudo

sudo du  /var/log 2>/dev/null

[tkaauf32]

@sdetweil

[sdetweil]

@tkaauf32 so, all the space is used IN the /var/log folder itself, not subfolders…

but 13040 is a tiny 0.1% WAY below the critical threshold… (if u are over 80% used, you are in trouble)

o

I don’t know what that means haha

the du command dumps out blocks used, and does it by folder.

in the last screenshot, there are 13040 blocks used for the entire /var/log subtree
there are 6846289 blocks of space on the memory card disk volume… so, divide

(13040*100) by 6846289 to get the percentage used = 0.19046815%

in system design, if u ever got over 80% used of the total capacity (memory, cpu, disk space), the system is in danger of failure ‘soon’… (I am a long time (45 yrs) computer system solution designer)

[tkaauf32]

@sdetweil I’m just curious how you think it went over 80% total capacity? Will this continue to happen over time? Or should i just buy a 16gig SD and it will likely solve the issue?

[sdetweil]

@tkaauf32 the bigger disk will help…

the Wolfram stuff is eating a lot of space.,

but I don’t see anything else really large taking a lot of space… MagicMirror is only taking about 10%
home folder is under 15%
