Hello kkm,

Welcome to forums, error itself is self explanatory, check your current path by doing pwd command and check it's file system seems it is 100% filled now, you may need to either increase its capacity or clean OLD junk log or un-necessary files(be careful before deleting any files though make sure you are NOT deleting anything important).

Thanks,
R. Singh

Hello kkm,

You haven't mentioned which O.S you are using? In case you are on *NIX system you could use uname -a command to check O.S complete details. Then you could check your file system's complete details by df command which tells how much capacity system is having. For clearing the file you should NEVER delete your actual/working data/Binaries you should only delete junk or log files(it depends on your software where they store it, I am not sure about it since you haven't mentioned any details).

You could use command:
Code:
find your_file_system_which_has_issues  -type f -size +500M

Above will give you all the files which are more than 500 MB size then you could take decision which ones are junk files(but again fair warning be very careful on *NIX systems we DO NOT have recycle bin so be very careful before deleting anything too). Also you could hit THANKS button at left of each post to anyone if you feel post is useful to you too, cheers and enjoy learning.

NOTE: I have used 500M in find command you could change size too in that command in case you DO NOT see any 500 MB size file in your system.


Thanks,
R. Singh

Hello kkm,

I could see / is 100% filled. You could use command:

Code:
find / -type f -size +20M

You could change the size of files in command and then you could check with your mates which things could be deleted(again DO NOT delete anything out of the box of Binaries), that you folks have to decide which things should be removed(look for app logs etc if they are not getting cleaned).

Thanks,
R. Singh
