/dev/md1 100% full

Hi All,

Need your help to fix MBL 3TB NAS drive. I am able to stream movies and songs to TV and even on laptop perfectly but today when i tried to login via /UI/login i couldnt login even when my password was correct.

Later i tried to search all the thread about the issue and than logged in using putty through ssh and was able to login with root user. I later tried to change password of admin user but i was not able to do. Further invesigating i discovered that my /dev/md1  is 100% full. Below are my file system 

XXXXXX:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md1 1.9G 1.9G 0 100% /
tmpfs 50M 0 50M 0% /lib/init/rw
udev 10M 6.7M 3.4M 67% /dev
tmpfs 50M 0 50M 0% /dev/shm
tmpfs 50M 9.9M 41M 20% /tmp
ramlog-tmpfs 20M 4.4M 16M 22% /var/log
/dev/sda4 2.8T 611G 2.2T 22% /DataVolume

I have already moved file daemon.log and daemon.log.1 to /DataVolume and still the /dev/md1 is 100% full. :frowning:

I also edited dynamicconfig.ini_safe as below


I did not restart the nas drive but i did try to login again and still not accepting my admin password through /UI/login

I remember i did upgrade the firmware in the month of december.

What would be the rootcause of this issue and how should i get the /UI/Login working back to normal like before.

If i do a reset of my hard disk will i loose any data?

Please help


You can try pressing the reset button on the back size for 4 seconds and that will not delete your files. 

I did try to reset my NAS drive but still the file system shows 100% full for /dev/md1

You need to find out which folder is eating up all your space. Run these commands in PuTTY and it will give you a list from smallest to largest and compare to mine. If something is way off, browse that folder in WinSCP and see if there are any odd files in that folder

I have the same issue. Any ideas how to fix it?

Uhm, did you read the post right before yours?

Hi Tony,

I found a folder /var/www/Software which contains smartware, user manual, etc. Do you think I can just took them out?



I can’t imagine what anything would be doing in there…

My /var/www/Software folder is empty.

I would guess it’s safe to remove…

Great! I don’t know why but there are smartwares, user manual and the date of the folder is 1970!. Weird.

Yea… I just noticed this.  My original Smartware share was actually empty.  I think it was used for backups by the WD software so I just removed the share but I see the files in my /var/www/Software as well.  Interestingly enough the Windows setup installers are missing. lol.  I’m going to delete them sicne they are probably not needed. :stuck_out_tongue:
