Are there some maps that are using a lot of space that i can remove without having problem,,
Or a better solution..

[Egregius]

ssh to it
cd /
du -h -d 1
"du -h -d 1" will show you the actual size of the folders.
Go in to the biggest folders and rerun the command until you find out what's eating your drive.

mmm you think i am smart .....
Only this screendumps are almost my max ,,

4.0G ./var

Why is /var so large? Maybe it's time to clean up some garbage there.

/var contains all logging. Check there what is using your disk

[Egregius]

well,
cd /var
sudo du -h -d 1

/var contains so much more than logging.
Recently I had same issue on one of my RPI's wich had a 2GB card. Appeared that all old kernels where still on the card...

Not when you still want to use the system afterwards.
So have you checked the subdirectories for large files. I would first check /log, /backups and /tmp

[Derik]

Just the first big ones?

Can i remove the older versions???
The only backup i wil give a lot of money is my Domoticz DB...
When my OS stock, i set a new os on my sd...

[jvdz]

Seems you aren't running the logrotate utility that normally would clean and compress logfiles to ensure they don't grow to that size.
EDIT: Looks like it was working till 25 January last year as there are compressed versions of auth.log

Jos

Ok
I did change nothing. [ i think ]
Just flash the sd and run domoticz on it...[ runs 2-3 years ]

Can i remove this log files..? [ in all the years i did not use this stuff ]
And the DPKG.Status old versions?
And the alternative and apt.extend. xx old versions?

[jvdz]

Why worry about the few Kb's of the DPKG? The issue seems to be the log files not being cleared.
You can find quite some hits on Google on this question around deleting auth.log, but think you really should fix the logrotate so the system won't fill up again over time.

Hero's....

And proud @ myself...

[Egregius]

I would run these commands:

sudo truncate -s 0 *.log -> empty all logfiles without deleting them and thus preserving ownership and permissions.
sudo rm *.gz -> remove all old compressed logfiles. This can also be done in /var/backups

Don't know what those btmp files are occupying 200MB, should google that to see if it's safe to remove/empty them.

Also, try to find out why logrotate doesn't run anymore, then that handles it automatically for you.
In the config files of logrotate you can specify how many .gz files are kept.

Code: Select all

linaro@cubie:~$ cd /var/log
linaro@cubie:/var/log$ sudo truncate -s0 auth.log
linaro@cubie:/var/log$ sudo truncate -s0 syslog
linaro@cubie:/var/log$ sudo truncate -s0 daemon.log
linaro@cubie:/var/log$ sudo truncate -s0 kern.log

And a few others:

Code: Select all

linaro@cubie:/var/log$ sudo truncate -s0 btmp.1					
linaro@cubie:/var/log$ sudo truncate -s0 btmp					
linaro@cubie:/var/log$ sudo truncate -s0 message					
linaro@cubie:/var/log$ sudo truncate -s0 messages					
linaro@cubie:/var/log$ sudo truncate -s0 auth.log.1					
linaro@cubie:/var/log$ sudo truncate -s0 debug					
linaro@cubie:/var/log$ sudo truncate -s0 messages.1					
linaro@cubie:/var/log$ sudo truncate -s0 kern.log.1					
linaro@cubie:/var/log$ sudo truncate -s0 syslog.1					
linaro@cubie:/var/log$ sudo truncate -s0 lastlog					
linaro@cubie:/var/log$ sudo truncate -s0 dpkg.log.1					
linaro@cubie:/var/log$ sudo truncate -s0 auth.log

also the tool 'ncdu' is helpfull, it is a graphical 'du' application

Seems a nice tool, thanks.

But not available on OS X and Synology so I searched some more and came up with these commands:

find biggest folders

Code: Select all

perl -e'%h=map{/.\s/;99**(ord$&&7)-$`,$_}`sudo du -h -d 1`;die@h{sort%h}'

find biggest folders and subfolders

Code: Select all

perl -e'%h=map{/.\s/;99**(ord$&&7)-$`,$_}`sudo du -h`;die@h{sort%h}'

Almost the same can be done with piping the du command to sort. This command will display all sizes in MB so not good for small files:
1 level:

Code: Select all

sudo du -BM -d 1| sort -n

With subfolders:

Code: Select all

sudo du -BM | sort -n
