[Solved] Strange vailable memory indication

thafener · Jan 6, 2015, 4:43 AM

Hi @all

Have a strange memory on my pfsense box running 2.1.5 RELEASE that the dashboard says that 92% of 104 GByte HDD
are in use ( see attachment )

I have read other post regarding this and tried the command```
du -d 1 / | sort -n -r


9998261 /
2831344 /var
921336 /usr
86724 /kernels
33988 /cf
28852 /client-export
28140 /boot
18316 /etc
14372 /lib
5888 /sbin
5356 /home
3344 /tmp
1716 /bin
452 /libexec
184 /root
68 /dist
40 /conf.default
5 /dev
4 /tank
4 /scripts
4 /rescue
4 /proc
4 /mnt
4 /media
4 /.snap

This seems to be OK but why is the indication that different or do I have a serious HDD problem ?
What could I do to troubleshoot this ?

Thx in advance

The attachment was missing. What is the exact error?

Check the disk usage as mentioned here also:
https://doc.pfsense.org/index.php/Filesystem_Full_/_Out_of_Inode_Errors

Thx jimp

I have read this thread and sorry for the missing attachment, it is on now. Problem is that there
is a big difference in the available free space shown in the dashboard and in the commandline output
I have posted.

cheers thafener

That is what the document I linked explains how to find. The space must be in use somewhere. Check "df -hi" and "du -h" (don't sort the output)

It's also possible that the filesystem is corrupt or needs a check.

If you create an empty file /root/force_fsck and then reboot it will force a disk check during the boot process.

Happy New Year to you all

The out put of df -hi shows this

Filesystem     Size    Used   Avail Capacity iused ifree %iused  Mounted on
/dev/ad0s1a    104G     91G    4.8G    95%     38k   14M    0%   /
devfs          1.0k    1.0k      0B   100%       0     0  100%   /dev
/dev/md0       3.6M     72k    3.3M     2%      39   727    5%   /var/run
/dev/md10      488M    6.0k    449M     0%       3   64k    0%   /var/tmp/havpRAM
devfs          1.0k    1.0k      0B   100%       0     0  100%   /var/dhcpd/dev

The output of the second command shows nothing extraordinary big, output is too big
to post here unfortunately.

So I will do the Filesystem Check during one of the next nights an in case this
does not work I am going to buy a new HDD.

By the way I am using a Intel SSD, may this be a Issue ?

Kind regards

Hi jimp

Thank you very much for your help and the useful hint, the Filesystem Check did the trick.
The filesystem shows 90% free again.

Kind regards
