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%

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)

o

I don’t know what that means haha

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

 du  /var/log 2>/dev/null

may need sudo

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

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?

/opt/Wolfram is taking a bit of space

notice I had /

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

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?

the du thing above should give u a clue where…

/dev/root                30358348    6863684   22210168  24% /

i don’t know why now vs before… you would have to find the next newest log file and scan thru it to try to determine what (if anything) important is going on
here is my list of files in /var/log

alternatives.log  btmp             dpkg.log        lightdm        syslog       user.log
apt               daemon.log       faillog         messages       syslog.1     user.log.1
auth.log          daemon.log.1     fontconfig.log  messages.1     syslog.2.gz  wtmp
auth.log.1        daemon.log.2.gz  kern.log        messages.2.gz  syslog.3.gz  Xorg.0.log
auth.log.2.gz     daemon.log.3.gz  kern.log.1      messages.3.gz  syslog.4.gz  Xorg.0.log.old
auth.log.3.gz     debug            kern.log.2.gz   mongodb        syslog.5.gz
boot.log          debug.1          kern.log.3.gz   motion         syslog.6.gz
bootstrap.log     debug.2.gz       lastlog         private        syslog.7.gz

no helper for module is ok, if the module doesn’t have helper… but u may be out of space

review /var/log for dusplicates of log files

syslog.n (these are old, probably ok to delete)
and syslog

etc

this might give u an idea where space is used

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

note that this starts at the root… I have a remote volume attached so it searches that too… ugh
and it only shows the top 10… head -n 10, u can up that number… but mostly bet its the logs
